  • CompatibilityFits: APC BP650S
  • 12V lead-acid chemistry powers APC BP650S UPS reliably
  • Two-battery cartridge kit restores full runtime in one swap
  • 100 % compatibility guarantee matches original equipment specs
  • 48 V total pack voltage supports extended backup performance

Compatible replacement for APC BP650S

This two-pack supplies 12 V lead-acid cartridges built to match the original APC BP650S specifications. Each unit delivers 48 W of capacity and is guaranteed 100 % compatible with the factory equipment. The set restores runtime for desktop or small-server UPS units that use cartridge #4.

Upgrade from depleted or aged cartridges

When the original batteries no longer hold charge, this pair returns the UPS to full backup performance. The jump is worth it if runtime has fallen below useful levels or if the unit signals a battery fault. Buyers needing higher wattage or extended runtime beyond 48 W per cartridge should select a higher-capacity model.

Questions about this item

Does the cartridge fit the APC BP650S UPS without modification?

Yes, the 12V lead-acid cartridge is built to match the BP650S form factor and drops straight into the battery compartment.

What is the common mistake when installing the two-pack?

Connecting the new batteries in the wrong order reverses polarity; follow the original wiring diagram and tighten each terminal before closing the cover.
