Nickel-Metal-Hydride Batteries

December 8th Fact-of-the-Day

Nickel-metal-hydride (NiMH) batteries have a useful life of about 400 charge/discharge cycles if they are not misused. They have four important advantages compared to nickel-cadmium batteries. They have 40-percent higher charge density. They run longer on a charge. They are more 'environmentally-friendly.' They have a less discharge memory and because of that they do not need to be deeply discharged before each recharge. However, occasional deep discharges tend to improve their run-time performance. ©2004 Martek, International. All rights reserved.
