Quick answer
Most John Deere lawn tractors, including the 100 Series (D, E, S, L, LA models) and the X300/X500 Series, use a 12V Group U1 battery. Our top pick is the UPLUS U1 360CCA AGM: sealed, maintenance-free and listed for John Deere. Before you order, look at your old battery and match the terminal positions (polarity) and height so the cables and hold-down still fit. John Deere dealers also stock genuine batteries.
A John Deere tractor battery only needs to crank the engine and run the PTO clutch and lights, so a good U1 AGM battery is plenty. Bigger V-twins and cold climates benefit from higher cold cranking amps (CCA). Most failures come from winter discharge, so a maintainer makes any battery last longer.

How to replace a John Deere riding mower battery
Step 1: Get to the battery
On most 100 Series tractors the battery is under the hood, in front of the engine. On many X300/X500 models it’s also under the hood. Turn the key off and remove it.
Step 2: Disconnect it
Disconnect the negative (–) cable first, then the positive (+). Remove the hold-down and lift the battery out.
Step 3: Fit the new battery
Set it in with the terminals facing the same way as before. Connect the positive first, then the negative. Tighten the bolts, refit the hold-down and add a little dielectric grease to the terminals.
Frequently asked questions
What size battery does a John Deere D130 take?
A 12V Group U1. Match the polarity and height of the original, or check the operator’s manual or John Deere’s parts lookup.
How many CCA does my John Deere need?
Most single-cylinder 100 Series tractors are fine with 200–300 CCA. V-twins and cold climates benefit from 300+.
Why does my John Deere battery keep dying?
Check for a key left on, a faulty charging system (it should read about 13–14.5V at full throttle), or a parasitic drain. Use a maintainer over winter.
