What Battery Does a Kubota L3130 Use?
The Kubota L3130 uses a 12V battery with a factory rating of 582 cold cranking amps and 133 minutes reserve capacity.
The common replacement is a Group 24 or 75D26R-style battery. The key is matching the physical size, terminal side, and cranking power.
Do not blindly buy Group 27. For the L3130, Group 24 / 24R / 75D26R-style replacements are the safer match.

Charging System Checks
Check battery voltage before blaming the starter
Look for about 12.6V on a fully charged battery
Running voltage should usually be around 13.8 to 14.5V
Slow cranking can be caused by dirty grounds
Weak charging can ruin a new battery
Battery Replacement Tips
Disconnect the negative terminal first
Reconnect the negative terminal last
Clean cable ends before installing the new battery
