  • Weight14
  • Compatible with Back-UPS NS 1250LCD models

Kit contents and purpose

This replacement battery kit supplies two fused 12V9A sealed lead-acid cells designed for the APC BN1250LCD UPS. It restores backup power for home-office workstations, networking gear and small server equipment that rely on this unit.

Upgrade path and timing

The kit replaces the original RBC109 pack when runtime has fallen below useful levels or when the UPS signals a battery fault. Swapping both cells at once avoids the imbalance that shortens the life of a single new battery paired with an aged one.

Build integration

The fused pair reuses the existing wiring harness so no soldering or crimping is required. Factory-fresh cells arrive ready to install with the included step-by-step instructions, freeing the UPS for immediate return to service.

Questions about this item

What physical space does the 12V9A battery kit occupy inside the BN1250LCD?

The kit contains two 12V9A sealed lead-acid batteries fused together and weighs 14 units, matching the original internal dimensions of the Back-UPS NS 1250LCD.

Which step do installers most often miss when fitting the replacement batteries?

Reusing the existing wiring harness is the critical step; the batteries arrive pre-fused, so the harness simply plugs into the same terminals without soldering or extra connectors.

When should the 12V9A batteries be swapped out again under normal use?

Typical sealed lead-acid cells in this UPS last three to five years; plan replacement when runtime drops noticeably or the unit signals a battery fault.
