The Best Battery Types & Replacements for Garage Door Remotes
When your garage door remote stops responding, it’s easy to assume the worst. Maybe the opener’s faulty, or the motor’s given up. But more often than not, the fix is surprisingly simple: a worn-out battery.
Knowing how to choose the best battery types for your B&D remote, and when to replace them, helps avoid unexpected breakdowns and keeps everything running smoothly. No tools, no guesswork, and no last-minute panics when you're trying to get out the door.
The Role of the Right Battery in Smooth Operation
Your garage door remote works hard every day to send a secure signal to your opener. The right battery delivers the correct voltage and current, ensuring the signal is strong enough to reach your garage door motor every time you press the button. Using the wrong type or a poor-quality replacement can shorten battery life, weaken range, and increase the risk of malfunctions.
With B&D’s range of remotes, sticking to the recommended battery type means better performance and fewer headaches.
Common Battery Types in B&D Garage Door Remotes
B&D remotes use reliable, long-lasting batteries that are easy to find in Australia. Here’s a quick guide to the most common options:
| B&D Remote Model |
Battery Type |
Typical Lifespan |
| Tri-Tran+ Premium Remote | CR2032 lithium coin cell | 1–2 years |
| TB6 Remote Control | CR2032 lithium coin cell | 1–2 years |
| Wall-Mounted Remote | AAA alkaline | Up to 12 months |
These best battery types are chosen for their compact size, stable power output, and ability to handle varying Australian temperatures.
CR2032 vs CR2025: What’s the Difference?
Both CR2032 and CR2025 are lithium coin cells, but there are small differences:
- Thickness: CR2032 is 3.2 mm thick, while CR2025 is 2.5 mm.
- Capacity: CR2032 has a slightly higher capacity, meaning it may last a little longer in some devices.
- Compatibility: Always use the exact type printed on your existing battery. Even a half-millimetre difference can affect how it fits and functions.
If your remote was designed for a CR2025, using a CR2032 because it might last a little longer could end up damaging the contacts or the housing.
How to Replace Your Garage Door Remote Battery
Replacing a battery in your B&D remote is quick and easy if you follow these steps:
- Open the battery compartment — most B&D remotes have a small slot or screw to release the back cover.
- Take note of orientation — the positive (+) side usually faces outwards, but always confirm before removing.
- Insert the new battery — match the exact type and ensure it sits securely.
- Close the compartment and test the remote.
If your remote still doesn’t work, try reprogramming it according to your opener’s manual or contact your local B&D Accredited Dealer.
Troubleshooting After a Battery Change
If a new battery doesn’t solve the problem, it may be due to:
- Worn buttons — contact pads inside the remote can wear out over time.
- Signal interference — nearby devices or thick walls can weaken the signal.
- Opener receiver issues — the garage door motor’s receiver might need servicing.
A quick visit to a B&D dealer can help diagnose the issue and avoid unnecessary replacements.
Tips to Maximise Battery Life
Even the best battery types need proper care to last. Here’s how to extend their life:
- Store remotes away from direct sunlight or moisture.
- Avoid pressing buttons repeatedly or holding them down unnecessarily.
- Keep spare batteries in their original packaging until needed.
- Use a wall-mounted remote in high-use areas to reduce wear on handheld units.
In most cases, lithium coin cells last 1–2 years, but heavy daily use can shorten this timeframe.
Safe Disposal of Used Batteries
Used batteries shouldn’t go in your household rubbish. Lithium coin cells can be harmful to the environment and dangerous if swallowed by children or pets.
Many supermarkets, hardware stores, and local councils offer battery recycling programs. Place your used battery in a sealed bag or tape over both sides before recycling.
Where to Buy Replacement Batteries
Replacement batteries for B&D garage door remotes are available from:
- Large hardware chains and supermarkets.
- Electronics retailers.
- Your local B&D dealer network.
Buying from an accredited dealer guarantees the battery meets the original specifications for your remote.
FAQs
-
What is the most common battery for B&D garage door remotes?
Most B&D remotes use CR2032 or CR2025 lithium coin cell batteries. These batteries offer a good balance of size, capacity, and long-term performance in typical Australian conditions.
-
Can I use a rechargeable battery in my B&D remote?
No. Rechargeable batteries may not provide the correct voltage, reducing performance. They also tend to lose charge faster, which can result in frequent failures.
-
How long should a garage door remote battery last?
Typically 1–2 years with normal use, though heavy daily operation may shorten this. If you're opening and closing the garage multiple times a day, you may need to replace it sooner.
-
Do temperature changes affect battery life?
Yes. Extreme heat or cold can reduce the capacity and performance of coin cell batteries. Storing your remote in a shaded or temperature-stable area can help prolong its life.
If your remote is due for a battery change, matching the best battery types to your B&D model keeps your garage door working smoothly year-round.
