Questions about this item

Does the APCRBC161-PW arrive as a single cartridge or are extra cables required?

The APCRBC161-PW is a complete sealed lead-acid cartridge measuring 11.50" L x 2.50" W x 4.25" H and weighing 11.1 lbs. It replaces Battery Cartridge #161 directly, so no additional cables or hardware are needed.

My UPS is a BR1350MS — is the APCRBC161-PW the correct replacement or should I choose a different capacity?

The APCRBC161-PW is listed as compatible with the BR1350MS, BR1350MS-TW, BN1500M2, BN1500M2-CA, BR1500M2-LM and BR1200SI. It replaces the OEM APCRBC161 cartridge used across all those models, so this is the correct single option.

What runtime can I expect from the 11 lb cartridge once installed in my BN1500M2?

The sealed lead-acid cartridge restores the original 18-month design life and factory runtime specifications for the BN1500M2. Actual minutes depend on the connected load, but the cartridge matches the OEM APCRBC161 capacity exactly.
