12V 9.0Ah AGM Replacement Battery

This sealed AGM battery delivers 12 volts and 9.0 amp-hours for Mighty Mule FM150 gate openers. It replaces the original 7.5Ah unit with a higher-capacity design that fits the same footprint. The maintenance-free construction allows operation in any orientation without electrolyte leakage. Buyers needing a different voltage or a larger case size should look elsewhere.

Questions about this item

Should I choose this 9.0Ah battery over a 7.5Ah unit for my gate opener?

The 9.0Ah capacity is higher than the 7.5Ah original, giving longer run time between charges while fitting the same space.

What does the 12V 9.0Ah rating mean once installed in a Mighty Mule GTO opener?

It delivers 12 volts with 9.0 amp-hours of storage, so the opener can run more cycles per charge than the lower-capacity pack.

Will the T1/T2 terminals connect directly to my Mighty Mule gate opener wiring?

Yes, the T1/T2 terminals are the standard fit for Mighty Mule GTO and FM150 models, allowing a direct swap without adapters.
