How to Change Garage Door Opener Batteries (Liftmaster & Chamberlain)

Power outages may mean you have to manually lift your garage doors everytime you want to gain access or use. It sucks, I know. Most garage doors are dirty and some are extremely heavy and can hurt your back when lifted manually. 

The good thing is you never have to manually lift your garage door, thanks to garage door opener batteries. Batteries have revolutionized how garage door openers work. 

They brought convenience and operational safety to garage door openers. It is estimated that at least five deaths in the 2017 wildfire season could have been avoided if the garage door openers had battery backups.

However, batteries wear out and require replacement. Changing batteries is a simple DIY task that you can accomplish yourself. Here is how to change garage door opener batteries when they wear out. 

Do I need batteries for my garage door opener?

Yes, you need batteries for your garage door opener. If you live in California, it is a legal requirement that all garage door openers must have battery backups. All garage owners in California must install garage door openers fitted with a battery backup. 

Owning a garage door opener with a battery backup goes beyond fulfilling the mandatory legal requirement. Batteries are not a luxury but a must-have component for garage door openers. 

Power outages are rare but inevitable. You don’t have to get shut from your garage nor do you have to lift the door manually when you have a battery backup. 

Battery backups allow you to continuously operate your garage door opener when there is a power outage in your block. A battery backup can last you up to 24 hours or the equivalent of 20 opening cycles.  

Other than fulfilling the legal requirement, here is why you should have a garage door opener with a battery backup:

  1. Safety – A power outage forces you to pull the cord and operate the door manually. This means safety features and components such as sensors are disengaged. You could easily end up shutting the door on your foot or pet while operating it manually without safety features. Suspending safety makes the garage an unsafe space endangering the lives of everyone in the garage.  
  1. Security – Your garage door is the largest entry point to your home. Leaving it wide open and exposed for a long time makes it an easy target for people with bad intentions. 

Your garage door opener loosens its security measures during a power outage. Functionalities such as automatic locks and cameras are disabled during such a time. Having a battery backup keeps it powered and running making your garage secure as always. 

  1. Convenience – Imagine being locked out of your garage space just because there is a power outage. It sucks, right? Well, a battery backup keeps all the functionalities of the garage door openers running bringing back the convenience you’re used to.
