Product Identity

The BatteryJack inc. UT1222 is a 12V 2.2Ah replacement battery built for Troy-Bilt mowers including the 12AE449D066 and 12AG836E011 models. It serves owners who need a direct OEM substitute when the original pack no longer holds a charge. Buyers who want more capacity or a different voltage should look elsewhere.

Build and Daily Use

Advanced AGM technology seals the electrolyte in glass-mat separators so the unit operates in any position without leakage. Gas recombination handles over 90 percent of generated gas during normal use. The maintenance-free design requires no water checks or specific-gravity readings throughout its 4 to 7 year expected life.

Compatibility Check

Verify that your mower uses a 12V 2.2Ah pack and matches the listed Troy-Bilt part numbers before ordering. Confirm the physical dimensions and terminal layout fit your battery tray and cable connections. Ensure your charging system is rated for AGM chemistry to avoid damage.
