Do's

• DO follow the manufacturer’s directions carefully for battery storage and care, and don’t overcharge batteries.
• DO charge your battery at room temperature (68°F to 72°F) to extend battery life. Batteries get warm during charging and use—this is normal. As a precaution, most batteries and chargers are designed to protect against overheating.
• DO remember to recharge your battery a few hours before you want to use it. Rechargeable batteries lose a percentage of their charge each day when left off the charger.
• DO keep battery contact surfaces clean by gently rubbing with a clean pencil eraser, cloth or rubbing alcohol. Dirty contact points are a primary source of charging challenges.
• DO use only chargers designed for your type of batteries. If unsure about compatibility, contact the product manufacturer.

Don'ts

• DON’T leave your rechargeable batteries discharged or unused for extended periods of time. To extend battery life, charge them at least every 6-9 months.
• DON’T recharge a battery unless it is specifically marked “rechargeable.”  Attempting to recharge a primary (non-rechargeable) battery could result in leakage or rupture.
• DON’T use rechargeable batteries in chargers that are not designed for the specific battery type.
