Don’t overcharge batteries. Follow the manufacturer’s directions carefully.

Don’t leave your rechargeable batteries discharged or unused for extended periods of time. To keep batteries fresh, charge them at least every 6-9 months.

Don’t dispose of batteries in fire. They can rupture or leak.

Don’t drop or cause unnecessary shocks to the battery.

Don’t carry loose batteries in a pocket or purse with metal objects like coins, paper clips, etc. This will short-circuit the battery, generating high heat.

Don’t recharge a battery unless it is specifically marked "rechargeable." Attempting to recharge a normal battery could result in rupture or leakage. Don’t use rechargeable alkaline batteries in a nickel cadmium battery charger.

Don’t give batteries to young children.

Batteries get warm during charging and use—this is normal. As a precaution, most batteries and chargers are designed to protect against overheating. For longer life, charge your battery at room temperature  (20°C to 26°C)

Keep your batteries in a cool, dry place, away from heat, moisture and metal objects.

Rechargeable batteries lose a percentage of their charge each day when left off the charger. Remember to recharge your battery a few hours before you want to use it.

Read the instructions on your device before installing batteries. Insert the batteries properly, following the symbols that show you the correct way to position positive (+) and negative (-) ends of the batteries.

Keep battery contact surfaces clean by gently rubbing with a clean pencil eraser or cloth. Rubbing alcohol helps clear dirt and residue. Dirty contact points are a primary source of charging problems.
