Choosing the right battery

Confirm your device’s voltage, current, battery holder or mounting method, and operating temperature requirements before installation. Actual capacity and service life depend on load, temperature and device conditions. For use near the stated temperature limits, contact Rome Tech for application guidance.

Do not recharge, short-circuit, disassemble or solder directly to the cell. Keep coin batteries away from children.
