Compatible UPS Models

This replacement battery cartridge restores runtime to APC UPS units including BN1500M2, BN1500M2-CA, BP1050, BR1200SI, BR1350MS and BR1500M2-LM. It is built for owners of those specific models who need a direct swap without wiring changes. Buyers whose UPS uses a different cartridge number cannot use this part.

Sealed Lead Acid Operation

The cartridge uses a 12 volt sealed lead acid design rated at 9 amps. It weighs 12 pounds and measures 16.5 L x 7.3 W x 7.09 H inches inside the UPS chassis. The sealed construction prevents electrolyte leakage during normal operation and requires no fluid maintenance.

Pre Assembled Cartridge Format

The battery ships as a complete cartridge assembly rather than loose cells. This eliminates the need for assembly tools or terminal crimping during installation. The one year manufacture date stamp lets technicians verify freshness before deployment. Solar compatibility is listed in the specifications.

Questions about this item

How do I install the APCRBC161 cartridge and which step is commonly missed?

Power off the UPS, open the battery door, disconnect the old cartridge, insert the new APCRBC161, reconnect the terminals, close the door, then turn the UPS on and let it charge for at least eight hours before relying on backup power.

What maintenance or replacement will the APCRBC161 need later?

The sealed lead-acid cells last roughly three to five years; plan to replace the cartridge again when runtime drops noticeably or the UPS signals a battery fault.

What limit appears first during a long outage with the APCRBC161?

The 9 amp-hour capacity at 12 volts determines total runtime; once that energy is depleted the UPS shuts down, so size your load accordingly.
