12 V lead-acid cartridge for APC NS3000RMT3U

This replacement battery cartridge fits the APC NS3000RMT3U uninterruptible power supply. It uses a 12 V lead-acid design and ships as a two-pack. The cartridge is built to match the original equipment specifications for direct installation.

Runtime depends on connected load

The NS3000RMT3U unit limits how long this battery can sustain power during an outage. Heavier loads reduce available runtime while lighter loads extend it. The cartridge itself does not set a fixed backup duration.
