I checked my battery compartment last night and inspite of my best efforts of soaking EVERYTHING in heavy baking soda solution, modifying the battery caps with the one piece cap and vent tube, and coating EVERYTHING with a GENEROUS coating of corrosion preservative spray after carefully cleaning and repainting everything in the battery compartment that needed it; my transmission oil cooler radiator and battery hold down hardware, as well as positive battery cable terminal were HEAVILY corroded; especially the trans. oil cooler radiator. What a poor design! And man was I PO'd!!!! I decided I was going to find a sealed AGM type battery that fit or make one fit! I had a VERY informative talk with Larry at Batterystuff dot com. and below is the battery that he located for me and is shipping me for $139 including shipping. I will follow up with a post as to how this battery fits as well as its performance. With 600 cold cranking amps; it should be more than adequate to start my 4410 and FINALLY do away with the corrosion caused by the inevitable release of hydrogen sulfide into the battery compartment and radiator area.

Wow. I would have thought for sure that the vent cap with tube would fix that. I'll have to check out my 4310 to see if it's doing the same thing. ....

You would be VERY wise to do so. I am surprised that my trans. oil cooler radiator is not leaking oil. The corrosion was pretty bad. I will eventually have to replace it because of the corrosion as once the acid starts eating it; the corrosion and deterioration is nearly impossible to stop. My hopes are that the heavy baking soda solution I applied will neutralize that acid corrosion. I think what made the corrosion so much worse was the very humid summer air. It does not take much hydrogen sulfide to cause a problem if water vapor is available. ....

I'm surprised you even took that risk of letting a standard battery stay put
I had a terminal that was corroding and the hold down bars, that was more than enough for me to get an Optima (51 series) -

I did the same treatment to my 4300 but still have the junk battery in. I had searched but found nothing that would fit yet although 1 company assured me they had a sealed one coming in that size. My Amish neighbor is a sort of battery store for the Amish and he gets me any normal batteries for about half price. He just gave me a deep cycle that matched the 4300 battery dimensions exactly, just does not have the same mount lugs or terminals. I do not know yet if it will crank enough but free and sealed are both nice words. If it does not work I will see about the one you found. ....

Joe, I have wanted to change to a sealed battery since day one. The 421,4310, and 4410 take a BCI Group 22NF battery which has the terminal polarity reversed and a funky size battery. The Optima 51R was just the right size but does not come with the battery hold down lugs on the bottom battery wall sides. Makes for a difficult modification to make a battery hold down work in that space. If the picture and specs I have interpreted correctly; this battery will hopefully fit just right and have an extra 100 cold cranking amps over the OEM battery as well as being sealed. ....

The 22NF is an odd size as the plates are smaller than the standard 6". The battery you found may be the only sealed unit sold. The price reflects the rarity. I checked the Deka guide as they make a large selection of AGM and gell batteries.
One option would be to go to a low gassing Ca based battery. The discription is in the Deka guide.
If it is any consilation the JD 750 and JD 955 have the same problem. Placing the battery over the front axel and next to the hot radiator is not a good idea for a battery. ....

I figured there was a reason why you couldnt do it -

I'm glad you are now able to do so, and the damage is repairable...what a nightmare waiting to happen

I wonder why this is considered only a JD problem (or is it?) when MANY tractors even older ones have a similar setup. Is there some difference?

For example at work we have two early 90's Ford (1720+1920) and each have well over 5000 hours and regular old vented batteries with no special precautions and they sit right in front of radiator...no problems.

My speculation would be that in the 4000 Ten series tractors; the battery is mounted directly up against and in contact with the transmission oil cooler radiator. The engine radiator is directly behind the oil cooler. The radiator fan draw a large volume of air through this area and the hydrogen sulfide gets draw directly into the oil cooler while still in a vapor state and condenses on the oil cooler surface. If the battery was located just a bit further away from the radiator area or down below is out of the air stream being drawn into the radiator; I think the problem would be greatly lessened if not eliminated. Any way you cut it; a very poorly thought out design on John Deere's part in my opinion. I think they could have at least applied a technical service bulletin that encased the battery in a vapor proof box or better yet, installed sealed batteries and replaced any damaged oil coolers or battery compartment components for customers with this issue. ....

Just a heads up for anyone considering ordering the battery I posted a link to above. The battery came in late yesterday and is the correct size dimensionally but for some odd reason did not have the hold down lugs on the sides of the battery as shown in the picture. I am working with the owner of Battery Stuff dot come work exchange this battery for one with the lugs. When I get it in and install it; I will post some feedback. In the mean time, I would suggest holdig off ordering this battery until they figure out what the problem is and ensure the batteries shipped have the hold down lugs. ....

Randy, I checked the battery compartment on my 4310 this morning and there isn't the slightest trace of corrosion or moisture. The dust on top of the battery and around the cap is as dry as a bone. Are you sure your machine isn't overcharging? Maybe the vented battery cap I have fits better than the one you are using. ....

Looks like that will be a good battery for your cause as it is suitable for in cab mounting for car audio. If cost is not an issue I would look at gel cell batteries. half the size with just as much power and can be mounted in any position. ....

Randy; You know me the SD. Attached is battery with a little more CCA's and a slimmer profile. There is a hold down case for it also. This would provide you with some clearance between the battery and the cooler. They say it is compatible with the 22NF. ....

Peters, thanks for the link. I will look into this. In the mean time, I am working on exchanging or returning the battery I currently have. If I can exchange this battery for a version that has the hold down lugs as shown in the link picture; it will be a perfect fit and match. ....

I checked back with MK who is the manufacturer of this battery and they tell me that the picture of the battery shown is out of date and incorrect. These batteries DO NOT come with the hold down lugs on the sides as shown in the picture. I am going to see if I can get a steel hold down bracket fabricated that I can put across the battery top and runs down the sides about an inch or two short of the OEM battery hold down nut plates. Hopefully this will allow me to use the OEM bolts and nut plates to secure the battery in place. ....

Because of this thread I also checked my battery and oil cooler location. I saw two 1 inch square areas that were white on the oil cooler but no corrosion yet. I blew the white off with compressed air and hosed it off with water. After 400 hours I don't see much, if any, damage due to the battery. I wonder if there are certain environmental conditions here that make a difference. ....

Perhaps one reason I have had more corrosion problems may be that I live and use my tractor in a fairly hot climate during the summer. Most times I am using it, the temps were over 90 degrees. The combination of the heat and hot oil in the oil cooler may have caused the battery to outgas more than normal.

If you had any corrosion on your oil cooler, I strongly recommend that you treat this area with a heavy baking soda solution. I used a tooth brush to scrub the baking soda solution in good until I got no more fizzing. I then sprayed baking soda solution over all of the components in the battery compartment to prevent any further corrosion. ....

The hold down at the bottom, PC680, of the link I sent allows you to mount in any direction. Is there nothing to mount it to on the 4010s? I know I could mount to the front of the compartment on the 955. ....

It's a standard 22NF battery. Cars have used that size too. Unfortunately it's not popular enough to warrant an AGM battery manufacturer to tool up for 'em. I wrote Deere a year ago asking them to get Optima to make a 22NF battery for their use. They acted interested in the problem at the time but nothing has come from it. ....

The 22NF is a standard BCI battery size but rare even in the normal range. It has plates that are less than 6" wide. They are a special run on any battery line. Let me do a little more hunting I thought maybe we had a solution with the even smaller AGM battery with carrying block.
Maybe I will give a call to East Penn. I know they have the 22NF cases and their AGM and gell lines are rather flexible. I know a couple of friends there are antique tractor restorers. We should have a more friendly ear than Optima. ....

The battery is installed now. A friend fabricated a battery hold down strap out of 1" wide x 1/8" thick strap iron. The strap basically run from about 3" from the bottom sides of the battery across the top and is heavily wrapped in "100 mph tape" to prevent the iron strap from shorting out the battery. I am going to add a piece of radiator hose or similar hose which has been split down the middle as added insurance. The iron strap has tabs or "ears" that are belt at right angle so the strap portion running down the sides of the battery and the tabs are drilled out and slightly elongated to allow the OEM battery hold down bolt to be utilized. I will get some pics posted and post a follow up to let everyone who is interested know how this mod works out. The battery starts the engine a bit easier than the OEM battery but after nearly 4 years, I think the Strong Box OEM battery is getting tired. Hopefully this will eliminate the outgassing & corrosion problem for good! ....

Randy, I've lost track. Which battery did you end up going with? I'm really surprised that the vented cap didn't work for you. Maybe yours didn't seal as well as mine. At this point I'm not looking for a solution but when my JD battery dies it will be replaced with an AGM. ....

Yet another update. To address any potential loosening of the hold down strap bolts; I am installing Ny-loc nuts or lock nuts on the bolts by threading the lock nuts down on the bolt thread portion extending out of the nut plats in the battery deck panel. This should prevent any possibility of the bolts loosening and seems to be a straight forward and reliable fix. ....

Randy, could you post a picture of your mounting strap so I could duplicate? I checked my 4200 today and have a little corrosion and some rust on the battery tray and I think the battery is original (2000) so it's time to change it. Also, did you consider a magnum tie wrap run over the battery top and through the bolt holes? Just a thought. ....

By "magnum" I meant a big ol' tie wrap. I've seen some that are 3 feet long and 1/2 inch thick with a tensile strength of 250 pounds or more. If you ran one through the existing bolt holes and ran another one through a drilled hole on each side of the battery I don't think it would be affected by battery acid and would hold just about anything securely.

Just a thought. ....

Another victim of the dreaded acid death of my oil cooler.

Started leaking last week, I tore it down and found the leak. Right side directly behind the battery. Tried the epoxy patch. Nope...

So off to the JD parts man. 160 bucks later along with a gallon of Hy guard.

Sometimes I think these engineers are also employed at Ford. Man do they lay some stuff out in the stupidest ways.

Well it finally happened. My strongbox from 2001 finally STB. It was about to start and then nothing. we tested it and it only had 7 cranking amps. charger says bad cell or something. Now my tractor is looking like a killer bee, no lights, no grill and 2 rubber straps holding in a battery that does not fit. It is an old lawnmower battery from a John Deere 400 I parted out on ebay and the only one I could find in a pinch with the terminals on the right sides. So is there a consensus on just the right replacement or has it still not been created. The one on the link chief posted looks right, but does it really exist or just the one he settled for. I had hoped my luck would last until one was available as a bolt in. ....

Ken, I believe it is probably NOT a sealed battery. It is maintenance free - but does have 2 caps across the cells that could be removed but are not meant to be removed (they are not screw caps). The the guy at the JD dealer told me it was sealed but I am not sure he knew what he was talking about. In any event - I have not had any problems with corrosion yet, I think that the climate here must have something to do with it. ....

I replaced mine with a Optima 34/78 marine battery. I have a winch and jumper cables that I run off of the studs. I removed the stock battery stop and welded a new stop back a little bit closer to the radiator. I used a piece of 1" angle iron across the top of the battery with 9" bolts to hold it down. Two years now with no corrosion or movement. Starts in all temps, -25 anyways. Runs the winch very well. Good thread. Thanks.
Edit: I have a sync-reverser tractor so I dont have a cooler, just a radiator. I had enough room to do this, With a cooler you may not. ....

Has anyone tried the Stronbox ST battery ? It appears to be a spiral cell,gel cell ?

StrongBox™ Silver Technology (ST) batteries



John Deere is pleased to offer StrongBox ST batteries. They deliver the same superior features as other John Deere StrongBox batteries, plus:

· Patented silver technology alloy construction is field proven to resist corrosion and provide longer service life in high-heat operating conditions.

· Efficient radial pattern provides faster high-voltage starts.

· Full-perimeter frame rails provide increased durability and longer service life.

· Positive cast grid design with increased internal grid wire diameter improves corrosion resistance and increases durability.

· Large lug width and weight provide increased durability and longer service life.

I show a TY25877 as the replacement part for the original, and am wondering if this new battery would be a better replacement instead of trying to rig a different size battery.

Good find! That is a new battery line they did not have when I purchased my replacement battery. According to the Deere battery line chart, this battery is an exact fit. The question in my mind is whether is is a sealed battery? The Deere info. states it is a "maintenance free" battery. Surely it must be a BIG improvement over the previous Strong Box battery. I will do some research on this and see what I can find out. If this is indeed a sealed battery; then this should definitely fix the out gassing corrosion problem. Thanks for posting that info.! ....

I have put about 75 hours of mowing and brush cutting on this battery and so far no evidence of corrosion and it starts the tractor with ease. All that was required was fabricating the battery hold down strap bracket.

My understand of the above Silver Technology Strong Box battery is that it is NOT a sealed battery and will still vent hydrogen sulfide into the radiator. NOT a desirable characteristic. ....

Not sure if this is a possibility or not but as I was going thru the Cabelas catalog I came across their battery section. They sell a group 22 AGM battery with the following dimensions...

Group 22, Cranking Amps 850, CCA 670, Reserve 95 Min, Weight 38.5 Lbs., (L"XW"XH") 9.37 X 5.5 X 9.25.

The write up on this battery is...

The next generation of lead-acid batteries, our revolutionary Advanced Anglers series uses a separator similar to fiberglass to hold the electrolyte in place. This physical bond between the separator fibers, the lead plates and the container completely eliminates leaks and makes these some of the most vibration- and impact-resistant marine batteries on the market. These completely maintenance-free 12-volt batteries also play double duty on the water, serving as either a cranking battery or a deep-cycle power source. In testing, this revolutionary design withstood over 400 drain/charge cycles, giving them a life span far surpassing conventional batteries. And they won't freeze, no matter what frigid conditions your boat endures during the off-season. Meets all EPA/OSHA marine requirements. FAA and DOT approved.

It is listed at $114.00 plus shipping. Just a thought if it will mount up.

These JD machines take a group 22NF, not group 22, which is what makes them hard to find. The 'F' indicates reversed terminals, which isn't so bad, but the 'N' indicates a narrower format than the group 22. It's really wedged in there. Group 22 and 24 were used in a bunch of cars, 22F and 24F in fewer, but 22NFs were hardly used in any. It's been 24 years since I sold batteries, so my memory might be a bit fuzzy, but I think this is all correct. ....

I don't disagree with you on what the BCI Group Size Chart says. I can only go back to the fact that Cabelas Group 22 battery is 9.37 inches long, 5.5 inches wide and 9.25 inches tall. Based on that, the Cabelas battery is just a hair shorter in length, the same size in width and 5/16 inch taller than the Group 22NF. It would fit in the space for a group 22NF battery as long as there is enough height clearance. Cabelas does not catagorize their battery as a 22NF or a 22F, they simply refer to it as a group 22.

It just might work. ....

kwschumm,

Go to the Cabelas home page, go to the Boating Section. Under Batteries and Chargers choose Marine Deep Cycle Batteries. Then choose Cabela's Advanced Angler AGM 22 Batteries and Power Packages. From there, choose Cabela's Advanced Angler AGM Batteries. The Group 22 is the first one on the list.

Frank,

Have you phyically removed the battery to look and see what is going on behind it? Everything looks A OK when I checked the area too until I decided to remove the battery to do some pressure washing. What a corrosion mess I found. If you haven't already, you may want to remove the battery and take a looksee.

Hopefully all is well when you pull the battery for a look. If by chance you do find some corrosion damage, spraying the entire area down with a hot water heavy solution of baking soda nutralizes the acid and stops the corrosion from progressing any further. Let is set for a day or so and then wash it off, clean up area with a wire brush and touch up paint. Looks as good as new. ....

Just an FYI for those who have the 4010, 4100, 4110, 4115 these machines use a group 51 series battery - which is an easy replacment using an Optima sealed battery. dosent matter if its the "R" version or not(you would just turn the battery around). The newer 2305,2320,2520 use the 22NF (why they did that who knows). There is a chance the Group 51 will fit (from Optima). I will be experimenting with this I think this weekend on a 2520 - will post on results when finished. ....

What do you think of this battery? It's 60 AH but I can't
find the CCA, and it doesn't have the side lugs, but neither does the SVR battery now.

I'm definately going completely sealed. ....

majsmith,

I initially looked at gel cell batteries but they will not work (at least not designed to). Gel cell batteries are designed for deep cycle discharge use in marine and RV applications. They require a nonstandard charging format that is not compatable with the alternator charging system on our tractors. (at least this is what was explained to me when I inquired about buying one for my 4410) Lastly, if this gel cell battery is similar to the battery I looked at which was also 60 amp hour, it only provides 300 CCA which is well below the 500 CCA of the OEM battery. The battery I went with is the battery I provided the link to. It is rated at 600 CCA and it is still going strong. This battery showed the tie down lugs on the side of the battery in the picture but the battery that arrived had none. I found out that there are so few calls for the tie down lug applications that the manufacturer discontinued them. I had a friend fabricate a tie down strap that goes over the top of the battery but still uses the OEM hardware and provisions. I wrapped the steel 1 inch x 1/8 mild steel strap with a generous application of 100 mph tape to prevent the steel strap from shorting out the battery and it has worked well so far. I have put almost a 100 hours on it so far. The problem with the Optima 51R is the location of the battery terminals. They may be a bit out of reach from the OEM battery cables. You will have to measure and see what works for you. ....

Major Smith and Randy - I looked at the site MS found and they have the AGM also and it is a little cheaper. It does not give the CCA, but I am sure it will compare to a normal 22NF. We looked hard and long for one earlier and I could not find a NA supplier. I must have spent a couple of hours with no success. Hawker is a european battery manufacture as is SAFT so they are importing them and selling in the US. Good find major. ....

Eric, the battery you are linking too has even less CCA capacity. Only 280 cold cranking amps. This battery will not work in this application either. I wish it would because these AGM and Gel cell batteries last a lot longer but just don't have the grunt cranking capacity for our tractor application. I believe the battery I am linking to is the same battery your link it to, just a different retailer. I talked to their tech rep at great length and this battery that I originally linked to in this thread is the only battery that will work. You may be able to make an Optima battery work. They have the CCA capacity. ....

The CA and the CCA are different CA is at 32 F and CCA at 0F. The CA is about 390 for the average 22NF and 425 at the max. The highest CCA is the interstate at 390. Most are more like 300. Likely the interstate has thinner plates with less continuous power. CCA is limited by the plate size and the number of plates. All this is dictated by the size of the 22NF case. The gel batteries are about 350 CA and 245 CCA. I am not sure you will see much difference in actual use unless you are up north. Remember there is less self discharge in the VRLA. If you let the battery sit for a week it is likely the VRLA AGM will have more amps than the flooded battery.
I think the battery Major found is a Gruber not an East Penn. Seaching there are a lot more 22NF on the net than when we looked. Posted are the specs on another 2 22NF VRLA battery manufacturers. ....

Chief; As you suggested I did pull the battery out yesterday, and reall other than a bit of paint gone off the steel the battery sits on I did'nt find much wrong. I pulled the screen from in front of the radiator, blew some air thru it and the radiator itself and did'nt see any thing wrong. I have no idea whether my dad's old rule on batterys has had anything to do with it or not, but he allways everytime he changed oil in anything put a squirt of motor oil on the battery posts, so I still do that just as if he was still watching over my shoulder. Kind of a mess at times, but never any corrosion on anythiong. Been doing that since the 49 Hudson, so probably will keep doing it. Frank. ....

I am going to post this again as the discussion seems to be heating up again. Unless I am missing something, this battery seems like it would fill the bill for an AGM battery with the dimentsions and cranking power needed for the JD CUTs.

I was going thru the Cabelas catalog I came across their battery section. They sell a group 22 AGM battery with the following dimensions...

Group 22, Cranking Amps 850, CCA 670, Reserve 95 Min, Weight 38.5 Lbs., (L"XW"XH") 9.37 X 5.5 X 9.25.

The write up on this battery is...

The next generation of lead-acid batteries, our revolutionary Advanced Anglers series uses a separator similar to fiberglass to hold the electrolyte in place. This physical bond between the separator fibers, the lead plates and the container completely eliminates leaks and makes these some of the most vibration- and impact-resistant marine batteries on the market. These completely maintenance-free 12-volt batteries also play double duty on the water, serving as either a cranking battery or a deep-cycle power source. In testing, this revolutionary design withstood over 400 drain/charge cycles, giving them a life span far surpassing conventional batteries. And they won't freeze, no matter what frigid conditions your boat endures during the off-season. Meets all EPA/OSHA marine requirements. FAA and DOT approved.

It is listed at $114.00 plus shipping. Just a thought if it will mount up.

My memory is rusty but the 22 is slightly bigger than a 22NF (I think the N is for NARROW) and the terminals are reversed. It's a tight fit so wider may not work, and you don't want the terminals too close to the radiator. It could work, too, but somebody would have to try one to see. ....

kwschumm, you are exactly right about standard group 22 being larget than std 22NF but when you look at the dimensions of the Cabelas battery you will see that it is the same width as the 22NF battery, the same length as the 22NF battery and just slightly taller than the 22NF battery. Granted, the terminals are not reversed like the standard Deere battery but I woul think turning the battery around will solve that. The Cabelas battery has threaded posts but that can be resolved with adapters from the local auto parts store.

From what I have found on my 4710, battery height is not an issue so this battery should work. It has enough power, it is compatible in size and it is advertised to work as a cranking battery as well as a deep cycle battery.

I have seen no issue with my current battery but when it is time to replace it, I think this will be my choice unless somethng better comes along.

Maybe my 4115 is different, but to me the least important number is the CCA.

I have no glow plugs to compromise the starting power and even in the coldest weather I doubt that I have ever used the starter for as long as a full second.

The point for me was to get a sealed gel cell that fit in the space provided. It has worked out very well.

The 4100 had glow plugs and the 4115 does not. One engine has direct injection and the other has indirect injection.

I just can't remember which one had what. ....

Ok..... I looked it up. The 4100 had indirect injection, glow plugs and quieter ignition.

The 4115 has direct injection, no plugs and noisier operation. ....

ALOHA! HAWAIIANBOB HERE; I JUST BOUGHT A NEW JD 115 A LAWN TRACTOR. THEY DELIVERED IT WITH A NEW BATTERY. I TOOK THE BATTERY OUT A SAW 2 SMALL SPECKS ON THE BATTERY HOLDER. I THINK THAT THIS WAS FROM AN ACID SPILL. I PUT A THICK PLACTIC BOTTOM PLATE DOWN AND THEN I GREASED THE WHOLE AREA WI GREASE, THEN I TURNED THE BATTERY UPSIDE DOWN TO CHECK FOR LEAKS, IT IS A SEALED BATTERY, NO LEAKS. THEN I PUT THE WHOLE BATTERY IN A HEAVY DUTY PLASTIC THICK BAG BEFORE I CONNECTED THE TERMALS. JUST IN CASE. ACID CAN CAUSE DAMAGE TO YOUR PAINT PLUS YOUR BATTERY WILL DISCHARGE LITTLE BY LITTLE IF NO PLASTIC IS UNDER THE BATTERY. ALOHA! HAWAIIANBOB ....
