Compatible UPS Battery Cartridge

This GreenTech replacement battery cartridge fits APC Back-UPS Pro BR 1600VA, BR1600MI and BR1600SI units. It replaces OEM part numbers APCRBC166, Battery Cartridge #166 and RBC166 with a 24V 9AH sealed lead-acid assembly. The pack is designed for users who need a direct drop-in substitute when the original cells reach end of life.

Install in Minutes

Each unit arrives tested, charged and ready to install so no initial conditioning is required. Installation typically involves opening the UPS battery door, disconnecting the old cartridge and sliding the new one into the same guides. The main risk is reversing the polarity connectors; follow the colour-coded leads and the keyed plug to avoid damage.

24V 9AH Rating

The electrical specification that determines compatibility is the 24V 9AH rating built from two 12V 9AH cells. If your UPS requires a different voltage or capacity this cartridge will not work. Buyers who need a higher amp-hour pack or a different form factor should look for an alternative part.
