How to use

Install the battery in the device matching the correct polarity markings. Charge the cell before first use with a compatible NiMH charger following the charger manufacturer’s instructions. Use standard charging currents recommended for 1000 mAh NiMH cells or follow the charger’s automatic charge termination. Do not attempt to charge with chargers intended for other battery chemistries. Replace batteries in sets with cells of similar age and state of charge to maintain balanced performance.

Usage recommendations

Store unused batteries in a cool, dry place and avoid high temperatures. For devices with infrequent use, remove batteries to prevent slow discharge or leakage. Periodically recharge used cells rather than leaving them fully discharged to prolong cycle life; follow the charger and device guidelines for best results.
