Compatible UPS Battery Kit

The RefurbUPS kit provides a direct replacement cartridge for Tripp Lite BC400 uninterruptible power supply units. It contains one factory-fresh 12V 7A sealed lead-acid battery designed for high-rate discharge. Installation instructions are included so the swap can be completed without specialised tools.

Replacing Worn-Out Cartridges

This kit restores runtime when the original BC400 or RBC51 battery no longer holds a charge after years of service. The upgrade is worthwhile once self-tests report reduced capacity or the UPS emits low-battery alerts during brief outages. Users who need extended runtime beyond a single cartridge should consider higher-capacity alternatives.

Sustained Load Behaviour

Under continuous discharge the sealed lead-acid chemistry delivers steady voltage until the cells reach their cutoff point. The high-rate design limits voltage sag during the first minutes of an outage, giving connected equipment stable power. Performance declines gradually as the battery ages, so periodic self-tests remain the best indicator of remaining service life.
