Compatible replacement for Back-UPS 350

This battery kit fits the APC Back-UPS 350 model and ships factory fresh for immediate installation. It restores backup power to the UPS without requiring soldering or specialised tools. The cartridge contains a single sealed lead-acid unit rated at 12 volts. Buyers who need a higher capacity pack for longer runtime cannot use this cartridge.

Capacity and headroom

The 12 V 7 Ah cell supports the UPS through brief outages and lets connected equipment shut down safely. Runtime scales with the load attached to the Back-UPS 350; heavier loads will exhaust the reserve more quickly. Systems demanding extended autonomy beyond the standard runtime will find this battery insufficient.

Questions about this item

Will the 12 V 7 Ah battery fit the BK350EI unit I already own?

Yes, the cartridge is built as an APC RBC2 compatible replacement and contains a single 12 V 7 Ah cell that matches the original BK350EI specification.

How can I confirm the new battery is working after I install it?

After installation, let the UPS charge for the recommended period, then run a self-test from the front panel; a passed self-test and normal LED status indicate the battery is functioning correctly.
