This battery fits the listed APC models requiring a standard 12V 7AH SLA pack. Buyers needing a different voltage, higher capacity, or lithium chemistry should look at other options. It is not intended for automotive starting applications or deep-cycle solar storage systems.

90% gas recombination extends service life

Questions about this item

How long will the 12 V 7 Ah rating actually run my UPS?

The 12 V 7 Ah capacity supplies the ampere-hours the APC ES500, ES550 or LS500 expects, so runtime matches the original RBC110 or RBC2 specification for typical desktop loads.

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

It uses the standard F2 faston tabs required by the APC ES500, ES550 and LS500 chassis, which caps the connection to the UPS's internal wiring harness.

Will the case dimensions fit the APC ES500 battery compartment?

Yes, the sealed AGM case is built to the same footprint as the OEM RBC110 and RBC2 packs, so it slides into the ES500, ES550 or LS500 tray without modification.
