Compatible UPS Replacement Kit

This kit supplies a single 12V 9A sealed lead-acid battery designed to fit the CyberPower CP800AVR unit. It restores backup runtime for home-office or small-business UPS systems that have lost capacity over time.

Direct swap for depleted cells

The cartridge matches the original form factor so it slides into the existing battery compartment without wiring changes. No extra cabling or mounting hardware is required, freeing the installer from sourcing separate connectors or trays.

Low self-discharge SLA chemistry

The high-rate discharge cell delivers steady voltage during outages while generating minimal heat in standby. Normal float charging keeps the pack cool and quiet, with no audible fan noise from the battery itself.

Questions about this item

How long will the 12 V 9 A battery sustain the CP800AVR UPS under full load?

Runtime depends on the connected load; the 12 V 9 Ah cell is rated for high-rate discharge but no specific backup-time figure is published for the CP800AVR at maximum capacity.

Does the sealed lead-acid cell generate noticeable heat or fan noise during continuous float charging?

The battery itself is silent and produces only modest warmth during float charge; any audible fan noise comes from the UPS enclosure, not from the replacement cartridge.

Which UPS models accept this cartridge without additional hardware?

The kit is built as a direct drop-in replacement for the CyberPower CP800AVR UPS; no extra cables, brackets or adapters are required.
