12V 9AH UPS Replacement Battery

The BatteryJack inc. WKA12-7.5F is a sealed lead-acid unit built with advanced AGM technology for UPS and backup devices. Its 100% OEM replacement design fits existing installations without modification. The maintenance-free construction uses absorptive glass mat separators to prevent electrolyte leakage in any orientation. Buyers receive a 24-month warranty on this new battery.

Sustained discharge with gas recombination

Under continuous load the AGM system absorbs sufficient electrolyte to deliver steady service over the expected 4-7 year life span. The sealed design controls gas generation and recombines over 90% of gases produced during normal operation. This recombination keeps internal pressure stable during long backup events. The non-spillable classification meets International Air Transport Association requirements for safe transport.

Verify terminal type and case dimensions

Confirm that your UPS uses T2 terminals before ordering this replacement. The battery measures 5.94in in length, 2.56in in width and 3.72in in height, so check the available space inside your enclosure. Weight is 13.16lbs, which may affect mounting hardware choices. Units needing a different terminal style or smaller footprint will not be compatible.

Questions about this item

Will the 13.16lb weight and 5.94in length of this 12V 9AH battery fit the tray of my older APC Smart-UPS unit?

The battery measures 5.94in long, 2.56in wide and 3.72in high and weighs 13.16lbs. Compare those dimensions and weight with the tray specifications of your UPS to confirm fit.

Do I need to supply any cables or connectors to use the T2 terminals on this sealed AGM battery?

The battery uses T2 terminals. You will need compatible ring or spade terminals and cables rated for the UPS current if they are not already installed in your unit.

How does the 24-month warranty on this 9AH AGM battery align with the 4-7 year expected life of my existing UPS?

The manufacturer provides a 24-month warranty and states an expected battery life of 4-7 years. The warranty covers defects; the service life depends on temperature, discharge depth and charge maintenance.
