Motorola NNTN4970A two-way radio battery - Li-Ion

Motorola batteries for two-way radios are especially designed, built and tested to take the tremendous abuse radios have to handle in the field. Hard knocks and extreme temperatures can cause batteries to lose power. And a sharp drop in power or rise in impedance can easily cause the radio receiver to completely shut down, or "desense."

Motorola Lithium Ion (Li-ion) batteries have a higher energy-to-weight ratio than NiMH batteries, offering a lighter, smaller power supply for more compact devices. They also offer a major advantage of not experiencing "memory effect."
