Faultless replacement battery
Replaced the backup battery in our LiftMaster garage door opener. Way cheaper than the name brand that was originally in the device, fits just fine and works perfectly. One note: the measurements they give on the website looked a little too large in the height vs. what I measured on the battery I was replacing. I finally realized that they were measuring from the tops of the 2 +/- terminals on the top, which added about 1/4 inch or so. Definitely recommend this as a replacement.

FAQs
How to replace liftmaster battery 485lm?
To replace the battery, open the battery compartment on your Liftmaster motor, disconnect the wires from the old battery, and slide it out. Connect the wires to the new Mighty Max ML5-12 terminals, ensuring the red wire goes to the positive terminal and black to negative, then secure the cover.
Can I replace a 12V 5Ah battery with a 12V 4ah battery?
While a 12V 4Ah battery has the same voltage, it provides less capacity. Using a 5Ah battery like the ML5-12 offers a longer runtime and is generally a superior upgrade for systems originally using 4Ah or 4.5Ah cells.
What is the difference between 12V 4ah battery and 12V 5Ah battery?
The primary difference is the Amp Hour rating, which measures energy capacity. A 5Ah battery holds approximately 25 percent more energy than a 4Ah battery, allowing your backup system to run for a longer duration during a power failure.
Is this Mighty Max battery an authentic USA import for India?
Yes, this is an authentic Mighty Max product sourced directly from the USA. Dropy India ensures that all personal care and technical equipment are genuine imports to provide international quality to Indian consumers.
What type of battery does my Liftmaster garage door opener take?
Most Liftmaster models with Evercharge backup systems require a 12V 5Ah Sealed Lead Acid (SLA) battery. The Mighty Max ML5-12 is specifically designed to meet these voltage and amperage requirements.
