Questions about this item

Which Sigma Power Systems 12V 35Ah battery fits my John Deere SST 18?

This single 12 V 35 Ah sealed lead‑acid unit is built as a direct replacement for the John Deere SST 18; verify your existing battery shows 12 V and 35 Ah before ordering.

What does the 35 Ah rating deliver in the mower?

The 35 ampere‑hour capacity supplies enough stored energy for typical cutting sessions on the SST 18, with runtime determined by the mower’s actual current draw.

What terminal type does the battery use and what does it limit?

It uses FP‑type terminals, so you must reuse your existing cables and connectors; the terminal style dictates which lugs can be bolted on.
