Battery GP Alkaline button R620 (model 164-U10) — coin cell replacement for electronics

GP Alkaline button R620 (model 164-U10) is a coin cell battery designed for small electronic devices that require stable low-drain power. This alkaline button cell offers a compact, single-cell format intended for straightforward replacement in products such as watches, calculators, key fobs and various small remote controls. The cell’s construction focuses on consistent voltage output for devices with intermittent or continuous low current draw, helping to maintain reliable operation without frequent charging or complex handling.

Advantages

The GP Alkaline R620 provides steady low-drain performance and a long shelf life typical of alkaline chemistry. Its compact diameter and thin profile make it suitable for tight battery compartments, and the cell is designed for safe, simple replacement by end users or technicians. Production and material choices emphasize predictable voltage under nominal loads and compatibility with a wide range of consumer and medical-grade small electronics.

Suitable for

• Wristwatches and timepieces
• Calculators and small handheld electronics
• Key fobs and small remote controls
• Medical devices with low power requirements (e.g., glucometers, hearing aids with compatible form factor)
• Small sensors and backup memory modules

Key specifications

• Battery type: alkaline button/coin cell
• Form factor: coin cell, thin circular design
• Intended use: low-drain electronic devices
• Typical characteristics: stable nominal voltage for low current draw
• Storage: long shelf life when stored in original packaging at moderate temperatures

How to use

To replace the battery, open the device’s battery compartment according to the manufacturer’s instructions and remove the depleted cell. Observe polarity markings and insert the new GP Alkaline R620 with the correct orientation. Ensure the compartment cover is securely closed and test the device after replacement. Dispose of the old battery in accordance with local regulations for alkaline cells.

Usage recommendations

Store unused batteries in a cool, dry place away from metal objects that could cause short circuits. Avoid mixing old and new batteries or different chemistry types in the same device. For devices that require continuous or high-drain power, consider alternate battery chemistries or consult the device manual to confirm suitability.
