What is the difference in the rechargeable batteries Electronic Engineering sells?
A For years, all portable radios were limited by the capacity of their Nickel Cadmium (NiCD) batteries. Technology advances in batteries and chargers have made Nickel Metal Hydride (NiMH) and Lithium Ion (Li-ion) batteries much more common. That move helps to keep heavy metals out of our landfills and also packs extra battery power into the same size battery pack as NiCD. Motorola’s Impres battery technology is another exciting change. With Impres, a microprocessor in the charger talks to a computer chip in the battery to make sure it’s never overcharged and always maintained in the best possible condition. That means your batteries will last longer and you will never overcharge again.
