Why Garage Door Opener Batteries Matter
A garage door opener battery is supposed to provide the device with an auxiliary source of energy for effective functioning. In case the battery is broken, it can lead to problems with its performance.
What is the function of the battery?
Although many people think that the battery installed in the garage openers gives power to the garage door on a daily basis, its primary role is to act as a backup in cases where there is no power, and as a memory retaining component in others.
The battery back up became widely known because some places required that there was access to their garages even when there were power cuts and other emergencies. As explained by LiftMaster, the backup battery fitted in the garage opener provides enough power for several cycles.
Why Is It That The Settings Remain Stored All The Time?
Typically, current models of garage doors use non-volatile memory when storing the programmed settings. The settings remain memorized by the opener even in case there is some sort of blackout.
The reason behind this is similar to the manner in which the settings in a cell phone remain stored despite turning the phone off and back on. While the battery provides the energy required for functioning, memory functions independently.
Therefore, changing the batteries does not mean that the code becomes lost.
How Do You Know Your Opener Battery Needs Replacement?
A bad garage door opener battery normally comes with warning signals that indicate its state of depletion before it fails.
Warning signs!
Beeping is the most apparent signal. There are cases where the opener produces beeping sounds whenever the battery’s voltage level goes down. It may even feature orange or red LED warning lights.
Warning indications are:
- Sluggish operation of garage doors
- Delayed opener reactions
- Remote unreliability
- Failure during blackouts
- Wall controller flashes
- Persistent low battery warnings
These signs are similar to those that you see with a failing flashlight battery. It might work occasionally, but overall, its functioning is inconsistent.
Differences Between Remote and Backup Batteries
The remote battery fails differently from the back-up opener battery. In cases where the wall-mounted opener continues to function while the remote is not working. It may indicate that the problem is the remote battery and not the back-up battery.
Failure of the opener back-up battery is noticeable during power outages or alerts, but remote batteries impact daily activities because they send signals to the opener.
Which Battery Should Be Used in a Garage Door Opener?
It depends on the opener and whether you are changing the battery for the remote control or the battery backup system.
Batteries for Remote Controls
These batteries are cheap and readily available. So, you make sure you know the current battery number before purchasing a new one. Specifically coin-type lithium batteries like:
- CR2032
- CR2016
- CR2025
Batteries for Backup Systems
Backup systems often make use of 12V rechargeable batteries. Most of the batteries for Chamberlain garage door openers have backup systems that work during an emergency.
In the case of Genie, some models might have different backup system batteries. Some backup systems offer up to 50 cycles when there is no power.
Take note that, the wrong battery can destroy the entire system or lead to its poor functioning.
How to Change Garage Door Opener Battery Without Losing Code
Replacing the battery is usually a simple process as long as care is taken not to reset the opener inadvertently and always following the manufacturer’s guidelines.
Before you start the process:
- Turn off the electricity if advised by the manufacturer.
- Stay away from exposed wires.
- Do not interfere with the springs, cables, and tensions.
- Use the right replacement battery for your opener.
- Always use gloves when dealing with batteries that might have leaked.
The garage door systems comprise movable mechanical parts that could harm you if improperly handled. Battery changes are safe but any other repairs are best left to the garage door repair experts.

- Make sure the battery is secure
How to Replace Batteries in a Garage Door Keypad
Typically, wireless keypads have either alkaline or coin cells located beneath the keypad cover.
Preventing Keypad Re-set Issues
Most homeowners tend to inadvertently cause the keypad to reset when changing batteries. Here’s how to prevent that from happening:
- Do it fast
- Don’t press any programming buttons
- Consider taking a picture of the program settings before you begin
In case of resetting, you will need to re-program the keypad with a new code using the process of learning. However, this differs across brands and models.
Why Is the Opener Not Working After I Have Changed Its Battery?
Despite changing its battery, the opener will still not work and may not be at fault.
Problems With Openers
Some of the most common problems with openers even when the batteries have been replaced include:
| Problem | Possible Cause |
| Beeping continues | Incorrect battery installation |
| Remote not responding | Dead remote battery |
| Door will not move | Power supply issue |
| Flashing lights | Sensor alignment problem |
| Keypad stopped working | Programming reset |
| Weak operation | Low-quality battery |
Sometimes, there could be an issue with the battery itself.
The low-quality batteries do not maintain stable voltage levels.
If replacing the battery does not solve the problem, you may have to consider contacting a professional to fix your garage door opener.
When to Hire an Expert
- If there is sparking or burning smell from the opener
- If the wiring seems to have damage
- If the motor hums but doesn’t move
- When your garage door keeps losing programming
- When the springs or cables look damaged
It is highly dangerous working with garage door springs because they are under very high tension. However, changing the battery is relatively safe.
Garage Door Opener Batteries: How Frequently Do They Require Replacement?
In general, the lifespan of garage door opener batteries is about one or two years if we talk about typical conditions.
Frequent usage, power outages, and increased temperatures can influence their performance and necessitate changing the batteries more often. The primary reason why people tend not to replace batteries can be the fact that an opener works just fine when connected to the power grid. That means that after a power outage, you might find yourself inside with the door not working.
Therefore, it will be advisable to replace batteries every two years and check them twice a year. However, a professional approach to maintenance will provide better results and determine the real issue.
Conclusion
It might be a lot easier to reprogram your garage door opener after replacing its battery than you expect. Luckily, there is an alternative for all owners of garage door openers because today’s models have the ability to save the programming data even when the battery is taken out.
No matter whether it concerns replacement of the backup battery, remote control battery or keypad battery, maintenance will ensure optimal performance of the opener.
Defective batteries lead to situations where you might not be able to use your garage door opener right away after a power outage or face continuous alarms and system malfunction. It is possible to avoid that if you change your batteries yearly or every other year.
Yet, wiring problems, damage to the components and non-working garage door opener system in general may need professional assistance.
