How Charging the Nickel-Metal Hydride Battery(1)?
NiMH batteries which use the NDV method or the thermal cut-off control tend to deliver higher capacities than those charged by less aggressive methods. The gain is approximately 6 percent on a good battery. This capacity increase is due to the brief overcharge to which the battery is exposed. The negative aspect is a shorter cycle life. Rather than expecting 350 to 400 service cycles, this pack may be exhausted with 300 cycles. Similar to NiCd charge methods, most NiMH fast-chargers work on the rate-of-temperature increas View the rest of this article
