12 V 18 Ah UPS replacement battery

This 12 V 18 Ah battery replaces the APC CP20B12BP pack in compatible UPS units. It ships factory-fresh and ready for immediate installation. The single-unit design keeps the swap straightforward for IT staff or home-office users.

Practical limits of lead-acid UPS batteries

Runtime depends on the load connected to the UPS, so heavy server draw will deplete the 18 Ah capacity faster than light network gear. Lead-acid chemistry also loses capacity over time and in high-temperature environments. The battery weighs 15 kg, so plan for safe handling during replacement. Buyers needing longer runtime or lithium chemistry should look at higher-capacity or alternative-technology packs.

Questions about this item

Should I choose the 12V 18A version or a different capacity?

This unit is a single 12V 18A battery that replaces the APC CP20B12BP pack, so no other capacity is offered for this model.

What runtime will the 18Ah rating actually give my UPS?

The 18Ah rating matches the original APC CP20B12BP specification, restoring the factory runtime your UPS was designed to deliver.
