I'm just curious. Does anybody know who makes John Deere OEM batteries?

It looks like Tudor in (India)- which is a subsidiary of Exide

Lead-Acid Battery Manufacturers and Brand Names List 2018

I've never heard of Tudor, but thanks for you reply!

I've been battery shopping this past week as mine died - looks to be original. Impossible to find a Group 45 battery anywhere which tells the cynic in me JD somehow has created a group unto itself for the sole purpose of selling their own product and discouraging the search for a non-OEM battery. Search the pn - TY25881 and you get Interstate MT-51 or I-45 !! Neither is available at my local dealer so I thought I'd try the Group 51 I removed from my Honda last year just because and replaced it with the comparable Interstate 51R. It's a 1/2" narrower than stock and identical in the other 2 measurements. The poles are reversed but the cables are such that they easily reach their proper pole. Fired right up and seems OK so far !! I was thinking I'd try and shoehorn say a Group 24 in there, but it appears too tight a fit !! Craig

Craig- have you tried to condition the old battery with a battery maintainer such as listed above by RaptorTerry?

On Edit--Have you checked with NAPA? They show a BCI 45

you are probably correct, JD has become the leader in screwing the consumer when buying their equipment, especially farming equipment with all their proprietary software and parts, but to be fair many large companies like GM have done the same thing to prevent anyone but the licensed dealer to work on the equipment..where you must go back to them to get repairs...the sign of the times, I have a 2013 825i and I will be looking to replace the battery this spring, I havent started looking yet for a replacement, but any battery with enough CCA and that will fit under the passenger seat should work fine..

Thanks Brad, I'll check out the NAPA suggestion. As for the "maintainers", I've got a box full of Schumacher units that seemed to work fine until the warranty period expired !! Funny how that works !! I was looking at batteries in Wally World the other day and saw a private label one that has turned to have some nice features for $20 so I bought one. So far, works fine (it better). I don't like W-M for a myriad of reasons, but it hurts to keep banging my head on Schumacher so why not. The "maintainer" Terry mentioned is a totally different piece of equipment that I'm thinking is overkill for my needs. My tractors are all 6V + ground and these little "maintainers" do the job when they don't break !! My riding JD mower is 18 years old - bought it new and to this day, I've never touched the battery !! Drive it into the shed in the Fall, stabilize the fuel and cover it !! Reverse it in the Spring and I'm good to go !! This all being said, I'm sure it dies this Spring, but it clearly owes me nothing at this point !! Thanks again, Craig

Please understand that a simple "maintainer" is a little different than a desulfurizing maintainer. A maintainer is not capable of removing the sulfur from the battery plates. I'm not saying a maintainer with a sulfur killer is the alpha and omega all for a battery, it's just more than a trickle charger. Make sure when comparing the 2 to understand they are not the same.

18 years for your mower battery? WOW! Impressive! I'd love to have an 18-year battery in each piece of equipment.

I'm up to 10 12-volt batteries and 2 6-volt.

I fully understand the basic maintainer is far from what Terry has to combat battery failure. Honestly, I never knew one existed like Terry has until this thread !! As for the mower battery, I try not to abuse it by stopping and starting frequently, but it sits covered for probably 6 months in an unheated pole barn in Winter and in that same bldg in Summer where temps often reach 100+ so go figure. Never been on a maintainer and never even disconnected for whatever reason. All this being said, I'll probably go out this Spring and end up replacing it !! How about a link to the product you use Terry ?? Thanks, Craig

Craig FWIW- I also have the same product RaptorTerry has referenced, actually two. One model that sits on my workbench that is capable of "conditioning/charging" multiple batteries at one time and a smaller unit that I use on my Gator and JD 3520. I have a couple leads coming off my battery Gator that I plug in when exceptionally cold (minus digits) also occasionally during the warmer months to "condition" the battery. These units are capable of 6 or 7 modes of conditioning the battery, impressive stuff !! Check them out.
