How to Use an Energizer Battery Charger

Disposable batteries tend to drain quickly making them costly to replace and they are not environmentally friendly. Rechargeable batteries are a better option for many because the batteries may be used over and over again; thus saving money and reducing waste. It is important to run the batteries completely out before recharging so that they do not build up memory, extending their life. Typically, the life of rechargeable batteries can last anywhere from 500 to 800 charges. Energizer is the number one selling rechargeable battery in the world as of 2010.

1. Open the package the charger is in. There will be two or four slots to hold the batteries depending which model was purchased. The standard battery size is AA but there will be a drop down lever that can be pulled down to accommodate AAA batteries if desired.


2. Open the package the batteries came in. Tear the package carefully so as not to damage the batteries or cut into them. Keep all the batteries together to ensure they do not become lost or dropped. Dropping batteries may cause damage to them.


3. Place the batteries on the charger. Place the batteries on the top and bottom of each slot indicated by metal prongs. The batteries go into the charger right side up with the pointed tips of the batteries facing the ceiling and the flat surface of the batteries parallel to the ground.


4. Plug the charger into an outlet. Look for the green light appearing at the top of the charger indicating the batteries are charging. The batteries will be completely charged in as little as two hours.


5. Remove the battery charger from the electrical outlet once the two hour charging cycle has completed. When the batteries are completely charged, the green light indicator will go away, indicating the charging cycle is complete.


6. Remove the batteries from the charger for use. If not using all batteries at once, store remaining batteries in a safe place.
