Motorola NNTN4190A - 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. Motorola Nickel-Metal Hydride (NiMH) batteries can work longer between charges than NiCd batteries of similar size, but do not operate as efficiently in extreme temperatures. NiMH contains fewer toxic chemicals, so disposal is more environmentally friendly.
