How To Change Battery In Liftmaster Garage Door Opener?
Changing the battery in a LiftMaster garage door opener is a simple task that ensures your system operates smoothly. The article guides you through replacing both the remote control battery and the opener’s backup battery.
If your LiftMaster remote is losing range or stops working, the likely cause is a depleted CR2032 battery, which you can easily replace by prying open the remote, removing the old battery, inserting the new one, and testing the remote.
Similarly, if the opener's backup battery—essential for power outages—needs replacement (typically every 2-3 years), you can disconnect the opener, remove the old 12V battery, insert the new one, and test the system by temporarily unplugging it.
Regular battery replacements, usually every 1-2 years for the remote and when alerted for the backup, keep the LiftMaster functioning reliably. The process requires basic tools and minimal effort, making it a straightforward DIY project.
