Compatible replacement kit

This kit supplies a single 12V 7A sealed lead-acid cartridge designed for the Tripp Lite AVR750U UPS. It restores backup runtime when the original cells reach end of life. The package includes one factory-fresh battery and printed installation instructions.

Verify model and voltage

Confirm that your UPS carries the AVR750U designation before ordering. The replacement is rated at 12 volts and 7 ampere-hours, so the host unit must accept those exact electrical specifications. No other form factor or chemistry is supported by this cartridge.

Sealed maintenance-free build

The SLA construction eliminates electrolyte checks and allows operation in any orientation. Standard F2 faston terminals mate directly with the UPS internal harness, so no adapters or soldering are required during the swap.
