Button cell battery Energizer CR2012 3V lithium, single piece

Energizer CR2012 3V lithium button cell supplied as a single piece is designed for small electronic devices requiring a compact, stable power source. This battery delivers a nominal voltage of 3 volts in a thin, coin-shaped form factor compatible with devices that accept CR2012-size cells. It is intended for low-drain applications where long shelf life and steady voltage are important, such as timekeeping and memory retention.

Advantages

The CR2012 cell provides a stable 3V output with low self-discharge for extended storage and reliable operation in low-drain devices. Its compact dimensions enable use in slim housings while maintaining consistent voltage until near end of life. Supplied as a single piece, the battery is convenient for direct replacement and maintenance tasks. The lithium chemistry offers good temperature performance and long shelf life compared with alkaline alternatives.

Suitable for

• Wristwatches and small clocks
• Key fobs and remote controls
• Calculators and small electronic toys
• Medical instruments and glucose meters (check device compatibility)
• Backup memory for electronic modules and motherboards

How to use

Verify the device manual to confirm CR2012 compatibility and polarity before installation. Remove the old battery using appropriate non-conductive tools if needed, taking care to avoid shorting terminals. Insert the new CR2012 cell with the correct orientation, ensuring secure contact with the device terminals. After replacement, check device functionality and reset date/time or settings if required. Dispose of the used battery according to local regulations for lithium cells.

Usage recommendations

Store unused batteries in a cool, dry place away from direct heat and metal objects. Do not attempt to recharge, disassemble, puncture, or incinerate. Keep out of reach of children and seek immediate help if swallowed. For optimal device performance, replace batteries before they reach end-of-life and use single-piece cells recommended by the device manufacturer.
