Compatible 12 V lead-acid pack for APC BK1250

This two-pack of PowerWarehouse 12 V lead-acid cartridges is built to fit the APC BK1250 uninterruptible power supply. Each unit is guaranteed 100 % compatible with the original equipment, giving server rooms and network closets a direct drop-in replacement. The pack restores runtime for critical loads without any wiring changes.

Sustained discharge keeps protected gear running

Under continuous load the batteries deliver steady voltage through the full discharge curve, avoiding the sharp drop-off seen in short-cycle tests. The 100 % compatibility claim means internal resistance matches the factory spec, so the UPS runtime calculator remains accurate during extended outages. A one-year replacement warranty backs the long-term reliability.

Questions about this item

How much heat does the 12 V lead-acid cartridge produce during continuous all-day operation?

The sealed 12 V lead-acid design generates minimal heat under normal float charge; it stays cool enough for closed UPS cabinets without extra ventilation.

What must I already own for the 2XRBC6SLA633 pack to work?

You need an APC BK1250 UPS that accepts cartridge #6; the two batteries slide straight into that unit with no extra cables or adapters.
