INVO INBA129 12V 9Ah Sealed Lead-Acid Battery

The larger of the two INVO cells in this batch: twelve volts, nine amp-hours, in the same sealed valve-regulated case that drops into a UPS or an alarm panel on spade terminals.

The extra two amp-hours over a 7Ah cell buy roughly a third more runtime on the same load, which is the difference between shutting a machine down cleanly and losing what was open. Check the voltage, the capacity and the terminal size on the battery you are replacing before ordering. One-year warranty.
