If you’re asking, “What kind of batteries do garage door openers take for their remotes?”, the answer typically depends on the model and brand of your garage door opener.
Lithium Coin Cell Batteries: The Most Popular Choice
Most garage door remote controls run on lithium coin cell batteries such as CR2032 or CR2025. These are flat, round batteries similar to those found in watches or car key fobs. Lithium coin cells are favored because they:
- Have a long shelf life (up to 5 years)
- Provide consistent power output
- Are compact and lightweight
Alkaline AAA or AA Batteries
Some remotes, especially older or larger models, might use standard alkaline batteries like AAA or AA. These are more widely available but tend to have shorter battery life compared to lithium coin cells. Make sure to check your remote’s manual or the battery compartment for the correct battery type.

For those wondering what kind of batteries do garage door openers take for backup power, many openers now include a built-in rechargeable battery. This backup battery is crucial for operating your garage door during power outages.
Sealed Lead-Acid (SLA) Batteries
The most common backup battery is a 12-volt sealed lead-acid (SLA) battery. SLA batteries are durable, rechargeable, and can deliver a reliable power supply for several years. They typically require minimal maintenance and are designed specifically for applications like garage door openers.
Nickel-Metal Hydride (NiMH) Batteries
Some newer garage door openers utilize NiMH rechargeable batteries, which are lighter and less toxic than lead-acid batteries. NiMH batteries offer good rechargeability and decent lifespan but may require occasional replacement depending on usage.
How to Identify the Right Battery for Your Garage Door Opener
If you’re unsure what kind of batteries do garage door openers take in your system, follow these steps:
- Check the User Manual: The most reliable source for the correct battery type is your garage door opener or remote manual. Manufacturers list the battery specifications clearly.
