Description
The CR2032 is a compact 3V lithium coin cell battery commonly used in garage door remotes, gate transmitters, access control devices and other low-power electronic equipment.
With a nominal voltage of 3V and the widely used CR2032 form factor, it provides a convenient replacement battery for compatible transmitters and accessories, including the e-Loop E-TX remote control.
🔋 3V Lithium Coin Cell
The CR2032 uses lithium coin cell technology to provide a nominal output voltage of 3V.
Its compact size and stable voltage make it suitable for low-power electronic devices where a small, lightweight battery is required.
Typical applications include:
- Garage door remotes
- Gate transmitters
- Access control remotes
- Wireless key fobs
- Electronic controls
- Security devices
- Small electronic accessories
📏 Standard CR2032 Size
The CR2032 designation identifies the standard physical size of the battery.
Typical dimensions are:
- Diameter: 20mm
- Thickness: 3.2mm
The standardised size allows compatible CR2032 batteries to be used across a wide range of electronic devices.
🎮 Garage & Gate Remote Applications
CR2032 batteries are commonly used in compact garage door and automatic gate transmitters.
They provide the power required for the transmitter electronics and wireless radio communication while maintaining a compact key-fob design.
A replacement battery may be required if the remote:
- Has reduced operating range
- Operates intermittently
- Requires multiple button presses
- Has a weak indicator light
- Stops transmitting completely
Battery condition should be checked before assuming the remote itself has developed a fault.
📡 Compatible with e-Loop E-TX
The e-Loop E-TX 4-button transmitter uses a replaceable 3V CR2032 coin cell battery.
This makes the CR2032 suitable as a replacement battery for compatible E-TX remote controls.
Replacing the battery can restore normal transmitter operation where reduced performance is caused by a discharged battery.
🔄 Easy Replacement
The CR2032 is designed as a replaceable battery.
When replacing the battery:
- Carefully open the remote or device housing.
- Note the orientation of the existing battery.
- Remove the discharged battery.
- Install the new CR2032 in the same orientation.
- Reassemble the device.
- Test operation before returning the device to service.
Avoid damaging the battery holder or electronic components while replacing the battery.
➕ Correct Battery Polarity
Coin cell batteries must be installed with the correct polarity.
The positive side of a CR2032 is normally identified by the “+” marking on the battery.
Always check the battery orientation before removing the original battery and install the replacement in the same direction.
Incorrect installation may prevent the device from operating.
📦 Useful Service Spare
CR2032 batteries are useful replacement items for gate and garage door technicians who regularly service remote controls and access control equipment.
Keeping replacement batteries available can allow a transmitter fault to be quickly diagnosed before replacing the complete remote.
