Rechargeable Batteries
That Have Very Low
Discharge Rates
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 batteries in landfills.

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 NiMH batteries.

All of the following VLDR batteries have the following common characteristics:

  • NiMH hybrid battery type
  • Are already charged at purchase time
  • NiMH battery charger required
  • Are environmentally friendly
  • Operate at voltage of 1.2v
  • Have no memory effect
