What Battery Does a John Deere 3032E Use?
The John Deere 3032E uses a 12V BCI Group 26R battery with 540 cold cranking amps.
The clean replacement target is Group 26R, 12V, 540 CCA. A higher CCA battery can work if it physically fits, but the safe factory-style answer is 540 CCA.
The “R” in 26R matters. It means the terminal layout is reversed. Match the terminal orientation before buying, or the cables may not reach cleanly.

Use Group 26R, not regular 26 unless terminal layout matches
Check battery tray size before buying an oversized battery
Clean cable ends before installing the new battery
Tighten the hold-down clamp so vibration does not kill the battery early
If the new battery keeps going flat, test the alternator and parasitic drain
