Before beginning any maintenance, disconnect the power to your LiftMaster opener. This is a critical safety step to prevent any accidental electrical shocks or damage to the opener.

Step 2: Locate the Battery Compartment

The battery compartment is typically found on the back or side of the motor unit. Depending on your model, it may be secured with screws or a simple latch.

Using a screwdriver, remove the screws holding the battery cover in place, then gently lift the cover to access the battery.
