Although rechargeable batteries used to be unusual, expensive and unreliable, they have come down in price and greatly increased in reliability. They are used exclusively in computers, cell phones and many other high-tech electronics, and are beginning to replace disposable batteries in other applications. Modern rechargeable batteries have many advantages over conventional disposable batteries. They last longer, cost less over their lifetime than replacing a series of disposables, and are better for the environment.
Instructions
1. Make sure the battery pack is one that you can charge. If it is a standard battery--such as a AA, D or 9-volt battery--that can be recharged, the word "rechargeable" will appear somewhere on it. If it is a laptop battery, camcorder battery or other specialized battery pack, it will not say "rechargeable," simply because those types of specialized batteries are always rechargeable.
2. Determine if the batteries can be recharged by simply plugging in the device they are used for. Cellphones, laptops and some camcorders automatically recharge their batteries when they are plugged in, which obviates the need for a separate charger.
3. If possible, recharge the battery before it runs out completely. Remove it from the circuit and plug it into the charger when it is at 1/4 power.
4. Set the correct voltage on the charger. Using too high a voltage can damage a battery, and using too low a voltage can result in incomplete charging. Most battery packs will have their voltage marked on them.
5. Check the pack frequently to make sure it is not overheating the first time you use it. If the charger is defective or improperly set up, it can overheat the battery and potentially cause an explosion.
