How can I confirm the 12V 7Ah battery is working correctly after installing it in my 850VA UPS?

After installation, power on the UPS and verify the status indicator shows normal operation. Run a self-test from the front panel or management software; the UPS should hold the 425W load for the expected runtime without alarms.

What does the replacement kit contain and is any extra hardware required for the swap?

The kit includes one factory-fresh 12V 7Ah battery cartridge. No additional cables, connectors or mounting hardware are needed; the unit is a direct drop-in replacement for the compatible 850VA 425W UPS.
