Compatible 12V battery pack for APC SU1000

This two-pack of 12V lead-acid cartridges is built to fit the APC SU1000 uninterruptible power supply. The batteries arrive new and are guaranteed to match the original equipment specifications. They provide a direct replacement when the UPS signals that its internal cells have reached end of life.

Steady voltage delivery during extended outages

Under sustained load the sealed lead-acid chemistry maintains a stable output without the voltage sag seen in short bursts. The design supports the UPS runtime needed to keep a server or network gear running through a prolonged power loss. Replacement restores the full backup duration the SU1000 was rated for.
