The shop doesn't have power, so the x750 has been sitting without a battery tender since November.

Got two Polaris 550 ATV's out there as well, and have been running them here and there.

Went out Saturday to start my ATV...click-click-click...

Grabbed key for wife's ATV...click...click...click...

No worries, the JD will start up...

Battery dead as a door-nail : (

Threw it on the charger for a couple of hours...still no dice.

Question: Is this a John Deere proprietary battery?

Battery recommendations?

Yes, will have power in the shed this spring and battery tender already ordered for ATV's and the JD...

I had the same problem couple years ago on my JD345 battery.
So, you need to head out on Pawnee Road (Hwy 36) down to Omaha to Tractor Supply and get a new Excide Group 51 battery. They have on sale for about $51.00 core exchange.

Yep says it on the battery.

Group size 51
Cold cranking 500amps

Quick online search shows anywhere from 50 to 300 per battery. Its a fairly common auto battery from any auto parts store for around 100. I prefer AGM style batteries but that's a personal preference.

I know you are planning of putting power out there but those cheap solar battery maintainers you can get at harbor freight work really well at keeping unused batteries happy in a cold shed.

Three to five years and the little Yanmar's love to shake the battery to death......Vibration is hard on batteries and few things vibrate like the 3 cylinder Yanmar in rubber motor mounts.:laugh::lol:

I would properly charge the battery at about 20 amps for a few hours and then load test it, just to be sure. Chances are if the battery is defective, it won't even take the charge so make sure you are using an automatic battery charger or keep an eye on it.

Harbor Fright sells their Battery Load Testers for $19.99 and EVERYONE should have one in their toolbox. Not only does it load test the battery, but when hooked up to a running vehicle, it also tests the alternator output, etc. Very handy tool to own.

It will also save a lot of time when electrical gremlins come calling on equipment because often, they are a dead cell in the battery. Can't tell you how many times people have told me "It's tests 12 volts with a volt meter so it's got to be something else," wrong. Many batteries test 12 volts when they aren't under a load. Put them under a load and watch the difference. Make sure it has either a rocker switch or similar to actually put the battery under load. Oh, what a difference it makes................

Also very helpful for testing alternator output and to make sure the voltage regulator is functioning. The diagnostics it provides for $20 makes this a must have tool for anyone who owns a vehicle with a 12 volt charging system and battery.

O'Reilly automotive sells a very good group 51 battery for about $100. It's what I replaced the battery in my 455 with and its a good battery.

My storage building doesn't have power either. I've been using a Deltran 10W Solar Battery tender on my compact tractor for years. It works great. I have it sticking in the window of my building. They make a 15W but it is too long to fit in my window.

Yes, the 'BCI Group Size' reference on the battery is the industry standard battery 'model'. This 'group' defines the physical size, terminal type and placement and, generally, the cold-cranking amps for a battery (though I've seen CCA vary within a group). OP should be able to search any battery manufacturer to find a suitable replacement. Deere is just good at hiding the standard info and labeling things with their own part numbers so people go back to the dealer to find replacements.

While you're doing the battery replacement make sure to check out your battery cables to see if the terminals/clamps are still firmly attached to the cable. See X758 Battery Cable Came Apart
