Rechargeable batteries are often sought as a money saving replacement for common alkaline batteries that can be used only one time before it is discarded. Rechargeable nickel cadmium batteries have been in the market for many years. However, nickel cadmium has limited uses. Lithium polymer batteries can be more versatile but great care is needed when recharging them and requires a special lithium polymer battery charger. The advantage of lithium polymer batteries is that the battery can be manufactured in a variety of sizes and shapes. The batteries have now found their way into laptops, cameras and cell phones. The polymer eliminates the need for the hard metal shell associated with other batteries reducing overall weight.

The polymer eliminates the need for the hard metal shell associated with other batteries reducing overall weight. However a lithium polymer battery charger must be used whenever using the lithium polymer batteries to prevent damage or possible explosion. Lithium polymer batteries are less stable than nickel cadmium alternatives and cannot be overcharged. They have a voltage limit at 4.2 volts when they reach maximum charge. Overcharging can result in either damage to the battery or a more serious explosion. It is, therefore, necessary to use the proper lithium polymer battery charger capable of preventing an overcharge. Many batteries are charged using a rapid recharge followed by a trickle down effect. The lithium polymer battery charger performs a rapid charge to eighty percent in approximately one hour then trickles down to a slower recharge rate until the battery reaches full charge. Lithium polymer batteries may cost more than the nickel cadmium alternative, but they also provide greater cost savings and versatility.

Lithium polymer batteries may cost more than the nickel cadmium alternative, but they also provide greater cost savings and versatility. It is possible that, some day, lithium polymer batteries may find their way into electric cars and would need a lithium polymer battery charger developed for this use as well. Lithium batteries and lithium polymer chargers are relatively new but their use will continue to grow with further development.
