Rechargeable Batteries
Many people know that it's better to use rechargeable batteries where possible in the interests
of helping to protect the environment. But still, people continue to buy disposable alkaline batteries for
various applications requiring a battery to hold a charge for lengthy periods of time. This continues to add
to the environmental problems of That Have Very Low Discharge Rates Now there's a solution to replace most of these alkalines with something better. People can buy a
rechargeable NiMH (Nickel Metal Hydride) cell that could effectively help eliminate the need to use
alkalines in most situations currently requiring long charge retention times. New Very
Low Discharge Rate (VLDR) rechargeable cells (also called hybrid rechargeable
batteries) hold their charge effectively for up to a year before needing a recharge. That means
(for example) you can put them in your TV remotes and forget about them knowing they'll work for the long
haul. Below is a list of brand names that provide these special VLDR All of the following VLDR batteries have the following common characteristics:
