12 Volt Battery Replacement

[Hugenpoet]

As mentioned, any auto parts or battery store can match up your battery. It would hurt to get the biggest battery with the most CCA that will fit in your battery case. Having top and side posts would be a plus. I deal with a store called Battery World, their prices are lower than the auto parts stores because that's all they sell.

Thanks

Hugenpoet - your owners manual will tell you. Your M7040 will take the same battery as mine - Group 31. I replaced mine last fall with a unit having 1050 CCA.
I was going to get an Optima AGM until I saw the price - WOW.

Thanks

One of the best things I've done to my tractor. I was fed up when my second group 51R (an Interstate) took a dump. The change gave me 800 CCAs and was pretty straight forward. I'd do it again in a heartbeat.

Ductape, I also have a B3030HSDC and live in NH. My battery is getting tired and I'm wondering what sort of modifications are required to fit a 34R battery in a space intended for a 51R. Would you be willing to snap a few photos of your setup or provide some additional written detail?

For reference, I've attached images of the stock setup. The end portion of the exposed tape measure is about the depth of a 34R as compared to the stock 51R.

We have had good success with our tractor batteries getting them from Tractor Supply. If there is a problem, (we even put a hole in one) they replaced it, no questions asked!

You can always try CAT Premium High Output Batteries.
CAT PHO batteries exceed industry standards in all five of the following stringent tests:
100 hour vibration test
72 hour deep discharge/recharge cycle test
30 day complete discharge test
Heavy-duty life cycle test
Cold soak test

Vibration and heat are two of the biggest killers of batteries. You may find something here that fits. No affiliation to CAT, just worked in the heavy electrical industry for 30 years.

A Odyssey AGM battery will be my choice when it comes time to replace my battery. Good for all of the stated reasons, shock, vibration, heat, cold etc. AGMs are just much better batteries for vehicles of all types, tractors included. If it's good enough for an A1 Abrams tank, it's good enough for my stuff.

While they are good, they are expensive, and sometimes paying double or more for a battery doesn't go down very well. Each to their own, I have had a few different AGM's before, and many other brands as well as CAT.

Unless Cat has changed their battery warranty policy lately, it was 5 year full replacement no pro-rated cost like so many have.

While they were great warranties, they have changed, Agricultural use 18mth replacement, +18mth prorata, car use 2 yr replacement, +4 year prorata.

Still good batteries, not sure how they compare on price in the US. Like all batteries, there will always be a dud one, and you may get it!
Just another option if you are interested, and you may or may not find something that suits, size wise, anyway!
EDIT: Just had a look, nothing small enough or similar to a group 51 there, will suit some other tractors though.

The one thing that AGM batteries can not tolerate is over charging. A flooded cell battery can tolerate over charging longer with a steady supply of distilled water to top up the cells.
