Common Battery Sizes for Garage Door Remotes Explained
When it comes to garage door remotes, you’ll often find yourself dealing with coin cell batteries like the CR2032, CR2025, and CR2016. Each of these batteries varies in thickness and voltage output, which can be pretty important.
For example, the CR2032 provides a stable 3V and has a thickness of 3.2 mm. This thicker battery actually offers a higher capacity compared to the thinner CR2025. Coin cell batteries like these are favored for their stable voltage output and compact size, making them ideal for remote controls and other small electronics.
Popular Coin Cell Types
Popular coin cell batteries power most garage door remotes, offering compact size and reliable energy output.
You’ll typically encounter lithium coin cells like CR2032, CR2025, and CR2016, each differing in thickness and capacity to fit specific remote models.
Some remotes, especially multi-button or older versions, may require cylindrical 12-volt A23 batteries instead.
Knowing the exact type is critical to maintain peak performance and signal strength.
- CR2032: Most common, 3.2 mm thick, high capacity
- CR2025: Slightly thinner at 2.5 mm, used in older models
- CR2016: Thinner, found in smaller remotes like Genie
- A23: 12-volt cylindrical battery for multi-button LiftMaster units
Always verify your remote’s required battery type before purchasing to guarantee compatibility. Replacing damaged or moisture-exposed batteries promptly helps prevent false signal transmissions that can cause unintended garage door openings.
Voltage And Size Differences
When selecting a replacement battery for your garage door remote, understanding the voltage and size differences is essential to guarantee proper fit and peak performance.
Common lithium coin cells like CR2032, CR2025, and CR2016 vary primarily in thickness: 3.2 mm, 2.5 mm, and 1.6 mm respectively, while maintaining a nominal voltage of 3 volts.
Using a battery with incorrect size may cause poor contact or damage the compartment. Some remotes, particularly LiftMaster’s multi-button models, require an A23 battery, which delivers 12 volts in a cylindrical form factor, differing markedly from coin cells.
Ensuring exact voltage and physical dimensions match the original battery prevents malfunctions and maintains signal strength. Always verify the printed code on your current battery or consult the manufacturer’s specifications before purchase.
Which Battery Size Fits Popular Garage Door Remote Brands?
Which battery size fits your garage door remote depends largely on the brand and model you own. Different manufacturers use specific battery types to optimize power and compatibility. Knowing your remote’s brand guides you to the correct battery, avoiding fit or performance issues.
Chamberlain remotes typically require CR2032; older models may use CR2025 or 9V batteries. LiftMaster units mostly take CR2032, though some multi-button or larger models need an A23 12-volt battery.
Genie offers CR2032 or CR2016 for keychain remotes; larger remotes often require A23 batteries. B&D and Craftsman remotes generally use CR2032 or CR2025 coin cells.
Check your remote’s battery compartment or manual to confirm the exact type before replacing. For safe handling and to avoid damage, always disconnect power before performing any maintenance or battery replacement on garage door systems, keeping in mind important safety precautions.
