Batteries are an important part of our lives. According to Green Batteries, a renewable energy website, more than 15 billion batteries are produced and sold worldwide, most of which are discarded after a single use. Rechargeable batteries are long-lasting, can provide superior power, as well as are environmentally friendly. A few simple steps in caring for rechargeable batteries get the most out of them.
Break In New Batteries
New rechargeable batteries come fully discharged. They should be fully charged before being used at all. It is typically recommended to fully charge and discharge the battery two to four times for it to reach its maximum rated capacity.
Avoid Memory Effect
While the actual battery run time will depend on the power used by the equipment the battery is in, there are actually a number of ways to ensure that the battery lasts longer. Rechargeable batteries work according to the "memory effect." This means that if a battery is only partially charged and partially used, then the battery forgets that it has the ability to charge and discharge more. For example, if you regularly charge your battery, then only use 50 percent of its capacity before the next charge, the battery will eventually become unaware that it has that extra 50 percent capacity. It will remain functioning, but only at 50 percent of its capacity.
To avoid this "memory effect," it is best if you fully cycle the battery, meaning to fully charge then fully discharge the battery. This should be done once every two to three months. To do this, leave your power device on until the battery has discharged completely. Once discharged completely, recharge the battery completely.
Impact and Heat
Avoid dropping or hitting the rechargeable batteries. A hard impact can sometimes result in the exposure of the corrosive cell contents. Similarly, keep the batteries away from fire or extreme heat as this could result in an explosion.
Battery Storage
Dormant batteries will eventually lose their charge, so it may be necessary to recharge if the battery has lain dormant for a long period. If the battery will not be in use for a while, you should remove them from the charger and place them in a cool, dry place.
Rechargeable batteries lose a certain percentage of their charge every day when left on the charger. Due to this, do not leave them on the charger once they have been fully charge. Remember to recharge batteries prior to using them, as they may have lost some charge. According to Energizer's website, batteries should be charged every six to nine months to extend their life.
Clean Batteries
Gently rub a pencil eraser, rubbing alcohol or cloth across the surface of your battery to keep it from getting dusty or dirty. Dirty contact points can minimize a full charge.
