What Battery Does a John Deere 1025R Use?
The John Deere 1025R uses a 12V BCI Group 22NF battery with 500 cold cranking amps.
The clean replacement target is Group 22NF, 12V, 500 CCA, 45 Ah. A higher CCA battery can work if it physically fits the tray and the terminals line up correctly.
Do not blindly buy a generic lawn mower battery. The 1025R is a diesel compact tractor, so CCA, battery size, and terminal fit matter.
