Demystifying Lithium-Ion Batteries for Power Tools: Choosing the Perfect Battery for Your Needs

Nickel-metal hydride batteries excel in safety and cell consistency, capable of providing high-rate discharge to meet the operational demands of power tools. Despite their lower energy density compared to lithium-ion batteries and heavier weight, their production costs and market prices are relatively low, making them quite competitive. Nevertheless, nickel-metal hydride batteries perform poorly in low-temperature environments and suffer from the memory effect.

Polymer lithium-ion batteries represent the high-end segment of power tool batteries. They boast the highest energy density and fastest discharge performance but come with a higher price tag. Their high-temperature performance is slightly inferior to that of lithium iron phosphate batteries and on par with nickel-metal hydride batteries.
