Button cell battery everActive CR1620 3V lithium — 5 pack

everActive CR1620 3V lithium button cell batteries in a 5-pack provide compact, replaceable power for small electronic devices. Each battery delivers a stable 3V output in a cylindrical coin-cell form factor sized for applications with limited space. The cells are intended for low- to moderate-drain devices where long shelf life and steady voltage are important, such as watches, calculators, key fobs, some fitness trackers and CMOS backup on computer motherboards.

Advantages

These CR1620 lithium cells offer consistent voltage and reliable standby performance over extended periods. Their compact coin-cell design fits recessed or slim compartments and is suited to devices that require minimal current draw over long durations. Supplied as a set of five, the pack allows multiple replacements or spare storage, reducing the need for frequent purchases. The chemistry and sealed construction minimize self-discharge, supporting long shelf life in storage and reliable operation when installed.

Suitable for

• Wristwatches and small timepieces
• Key fobs and remote controls
• Calculators and small handheld electronics
• Motherboard CMOS/BIOS clock backup
• Certain fitness trackers and medical devices with compatible size

How to use

Check the device manual or existing battery marking to confirm CR1620 is the correct size and voltage. Power down the device if applicable, then open the battery compartment or remove the case back according to the manufacturer’s instructions. Observe polarity when inserting the battery: the positive side (marked +) faces outward in most devices. Ensure the cell sits flat in the holder and close the compartment securely. Dispose of used lithium cells according to local regulations for battery recycling or hazardous waste.

Usage recommendations

Store unused batteries in a cool, dry place away from metal objects that could short them. Replace all cells of the same type at the recommended intervals to avoid leakage or unpredictable device behaviour. Do not attempt to recharge, dismantle or expose the cells to fire or high temperatures.
