Quick & Easy Guide: How to Replace Your Chamberlain Garage Door Opener Backup Battery

[@skarekat]

Really useful video. My Chamberlain garage door opener backup battery just died after 10 years, so based on this video I ordered the Mighty Max ML5-12 12V/5Ah from Amazon for $16.99. The installation was very simple, exactly as explained in this video. I tested the battery driven operation of the garage door after installation and it checked out great. Thanks a lot for this great information.

How do you open this thing. There are no buttons and I don’t want to break anything.

Thanks, this was an informative video. Quick question, should I unplug the garage motor for safety and does the battery have to charge for a period of time after installation?

[@phjohnso]

you don't have to but if you feel safer then do unplug it - you do not have to wait after installing it as it will charge up over time. Thanks!

@@phjohnso YES! per Chamberlain manual!

Will the garage door opener still works if there's electricity (ie plugged in)? Thanks

[@phjohnso]

@@melodysliu absolutely

I was surprised that you didn't unplug your garage door opener prior to removing the battery.

[@phjohnso]

I know but I didn’t need to.

[@camrongregor2607]

@@phjohnso I'm waiting for Amazon to deliver my battery. I'm not an electrician so are you saying that as an electrician it's safe not to unplug the garage door opener?

[@phjohnso]

@@camrongregor2607 feel free to unplug it by all means. It’s safer that way
