Most power tools are equipped with nickel-cadmium batteries. Nickel-metal-hydride batteries have been tried with limited success. While longevity remains a problem, new designs have improved. Lithium-ion is too delicate and can’t provide the high amperage. Lead-acid is too bulky and lacks persistent power delivery. The power tool has simply no suitable alternatives to the rugged and hard-working nickel-cadmium.
Although advancements are always pursued, sometimes it’s prudent to just stick with what works.
