NiCd Battery life cycling?
NiCd Battery life cycling? NiCd Battery life cycling? The NiCd Battery ?? In terms of life cycling, the standard NiCd is the most enduring battery. we examine the capacity, internal resistance and self-discharge of a 7.2V, 900mA NiCd battery with standard cells. Due to time constraints, the test was terminated after 2300 cycles. During this period, the capacity remains steady, the internal resistance stays flat at 75mW and the self-discharge is stable. This battery receives a grade 'A' for almost perfect performance. The readings on an ultra-high capacity NiCd are less favorable but still better than other chemistries in terms of endurance. Although up to 60 percent higher in energy density compared to the standard NiCd version, the ultra-high NiCd gradually losing capacity during the 2000 cycles delivered. At the same time, the internal resistance rises slightly. A more serious degradation is the increase of self- discharge after 1000 cycles. This deficiency manifests itself in shorter runtimes because the battery consumes some energy itself, even if not in use. more info:www.good- battery.co.uk
