Roller Shutter Door Doorbell Alkaline Battery 12V 23A 27A 40mAh 60mAh 10x28mm Small Cylindrical Cell for Garage Gate Bells Security Systems
12V Alkaline Battery for Roller Shutter Doors Doorbells 23A 27A Small Cylindrical Cell

This 12V alkaline battery is designed to power roller shutter door receivers, wireless doorbells, and gate security systems that require a compact cylindrical power source. With nominal capacities of 40mAh (23A model) or 60mAh (27A model), it delivers a steady voltage for low-drain applications. Measuring just 10mm by 28mm, the battery fits snugly into standard battery compartments found in many garage controllers and alarm panels. Choose the right capacity for your device to ensure consistent performance.
Features and Construction

Built on established alkaline technology, this battery offers dependable discharge characteristics suited to intermittent use. The two model variants let you match the required capacity without overspending.
Voltage and Chemistry
Rated at 12V nominal, the battery uses alkaline chemistry (zinc-manganese dioxide) to provide a stable energy output for doorbells and remote receivers. Alkaline cells are well suited to low-drain devices that require reliable voltage over extended periods.
Size and Fit
The compact dimensions of 10mm diameter by 28mm height allow installation in tight battery slots. This standard cylindrical size is common among roller shutter door systems and wireless doorbell units.
Compatible Uses

This battery is intended for use in devices that specify 12V alkaline cells in 23A or 27A formats. Typical applications include garage door openers, gate receivers, and security keypads.
Roller Shutter Doors and Gates
Roller shutter door receivers often rely on 12V alkaline batteries for short-range wireless communication. The 23A or 27A cell provides the necessary voltage for reliable signal transmission.
Doorbells and Security Systems
Wireless doorbells and alarm panels frequently use these small 12V batteries. Replacing a drained battery restores the chime or sensor function without any rewiring.
Buying Considerations

Selecting the correct capacity ensures your device operates as intended. The 27A model offers higher capacity (60mAh) for longer service intervals between changes.
Capacity Selection
If your device manufacturer recommends a 27A battery, the 60mAh variant provides more runtime than the 40mAh 23A. Always check the existing battery model before ordering.
Single Pack Supply
Each pack contains one battery. For devices requiring multiple cells, purchase the corresponding number of units. The battery is ready to install with no additional adapters needed.
