Garage Door Opener Battery: Changing and Replacing Your Battery

You come home from work one night and all of a sudden your garage door starts beeping at you. To your surprise, you look around thinking you have pressed the wrong button or set an alarm off, not knowing what the issue is. More than likely, it’s an issue with the garage door opener battery.

Well if this sounds like you and you are hearing this sound for the first time, then it could be a garage door opener battery problem that you are facing. The battery could either be in your remote control that operates the garage door to close and open, or it could be the battery backup that is connected to the door.

The beeps will also commence at different times and different periods, with each meaning a different thing. The best advice is to consult your owners manual as each garage door operates differently.

But, we will help you identify some of the most common beeping problems here and what you need to do to restore full functionality to your garage door.

Beeping Every 30 Seconds

If you find that the beeping is consistent every 30 seconds, then there are a couple of things you need to look for to diagnose the problem. The first is to look at the battery LED light and check the color that is being displayed on it.

If your garage door opener battery is showing an amber color that is flashing, then it merely means that your battery is low and need charging up. If it is in a solid red state, then, unfortunately, it means that your battery is dead and cannot be recharged.

If the red LED is showing, then you need to replace the battery.

If the amber flashing LED is showing, then you need to check the electrical outlet to make sure it is working and there is power to the door. Sometimes this is the most common problem for an amber flashing light, and you should see it return to green quickly.

However, if you have swapped the electrical outlet but the amber light is still flashing then it could be an issue with your garage door opener battery so you will need to replace it with a new one.

Beeping Every 2 Seconds

Apart from being very annoying, the two-second beeping noise that you hear coming from your garage door could mean that there isn’t enough power going into the battery and the door is only using the battery charge. If this is the case, take a look at the LED on the battery, which should be showing a solid amber light as opposed to the flashing light we mentioned above.

Sometimes this could be down to a power cut in which the house has suffered a reduction in power or a blown fuse. Make sure that full power is restored to the house and then go back into the garage to see if the LED has returned to its standard green display.

If the LED is still solid amber, then you will need to check the electrical outlet and swap over to another one. This should sort the problem, but if it doesn’t, then you may have a faulty garage door opener battery that will need replacing.

Ruining a Battery

One thing that many garage door owners do not know is that if you run a battery too low, it will never recharge again, and more importantly, it will cost you money to get a new one in place of it.

Generally, a garage door opener battery will last around 24 hours by just using its own source of power. In this time, you will need to find a working electrical outlet to keep the battery charging, so it doesn’t get too low.

If you know that normal power isn’t going to be resumed, then its best to disconnect the battery from the garage door and find somewhere to charge it or leave it disconnected until you know standard power to the electrical outlet will resume.

This will save you the time and money of having to buy and fit a new battery to the motor on your door.

Wi-Fi Operated Doors

Finally, if you use WiFi for your garage door opener, then you will need to look at a variety of different issues, from fast beeps to long beeps, right through to sequence beeps. Usually, the problems are down to the connection between the server and the door, or the network being accidental erased.

If you are controlling your door with Wi-Fi, then it is best to consult the manual to see what the beeps mean to diagnose the issue. You don’t have to call in an expert for this repair; you just need instructions to show you the steps to regain regular service.

Replace the Garage Door Opener Battery in the Remote

Maybe you stumbled upon this article hoping to fix the battery in the remote, or key fob, for your garage door opener.

There are a few simple steps you can take to fix that.

1. Open your garage door remote

Most likely, you’ll see a cover on the back of the remote that can be removed. If not, then the entire remote can probably just come apart in two pieces.

Remove the cover by simply pressing and sliding it.

There also could be a screw holding it shut. If that’s the case, simply get a small screwdriver to open it. You may need one as small as the ones that come in eyeglass repair kits.

2. Identify the battery, remove it, and get a replacement

The garage door opener battery for your remote should look like a small, circular coin. It may be a very small alkaline battery, but that is rare.

These coin-shaped ones simply slide or pop right out.

Take this battery with you to the store. Someone can help you find a match if you have trouble, but the battery type should be printed directly on the battery to help you.

The type will be an arrangement of letters and numbers.

3. Insert the battery and re-program the remote

Finally, insert the garage door opener battery to your remote. Replace the cover, following the steps to open it in reverse.

Then, you’ll most likely have to re-program your remote. This isn’t as difficult as it may seem.

Many modern garage door openers come with a single button to pair your remote. However, older openers will use a dip switch.

Find the model number of your garage door opener and look up the manual online, or if you have a physical copy.

The manual will give you a step-by-step guide on re-programming the remote.

Summing It Up

Overall, charging and replacing a garage door opener battery isn’t too complicated. The hardest part is figuring out what exactly the issue is, which we’ve hopefully helped you do.

If you’re still having trouble, it may be best to consult with an expert, or call the company who installed it.
