In comparison, nickel-metal hydride (NiMH) rechargeable batteries are capable of enduring 400 to 700 charge cycles while maintaining an output of 2000 milliampere-hours (mAh).
Disposable vs. Rechargeable
Disposable alkaline batteries offer a significant advantage in terms of shelf life, lasting up to 10 years, but they incur a higher cost per cycle of $0.30 to $0.50 per use. In contrast, rechargeable batteries provide a much lower cost per cycle of $0.01 to $0.05, with the potential for up to 500 uses.
For applications such as remote controls or clocks, disposable batteries are particularly suitable due to the absence of a required charger and their consistent 1.5V output, which avoids the approximately 20% initial capacity reduction commonly observed in rechargeable batteries like nickel-metal hydride (NiMH).
However, disposable batteries contribute to substantial environmental waste and typically endure only 2 to 3 years under intermittent usage conditions, lacking the long life of rechargeable options.
Rechargeable batteries achieve a return on investment within 10 to 20 cycles. For example, an $8 nickel-cadmium (NiCd) battery pack can surpass the performance of 20 alkaline batteries priced at $0.50 each (totaling $10), resulting in a $2 savings after 15 cycles.
An Energizer study demonstrates that NiMH batteries can reliably power two-way radios for up to 300 shifts.
To maximize performance, it is advisable to monitor charge cycles using applications such as Battery Logger, charge batteries to 80% capacity, and store them at room temperature to extend their longevity.
