Good battery. Fits right into my Garage opener. I just pulled out the dead one and replaced with this.

Battery works great for my Liftmaster 3850p

This backup battery is a perfect fit for my garage door opener which is a Liftmaster model 3850p. It is the same size as the original backup battery (485LM) and fits perfectly in the slot. Super easy to replace/install. This is a much cheaper price then getting an OEM replacement (485LM). Works great!!
