Follow manufacturers' maintenance guidelines, avoid over-discharging, keep batteries cool, and store two-way radios in a dry, temperate environment.

Various materials are used in construction, including Lithium-Ion (Li-Ion), Nickel-Metal Hydride (NiMH), and Nickel-Cadmium (NiCd).

Two-way radio batteries typically operate in VHF (136-174 MHz), UHF (400-512 MHz), and 900 MHz frequency ranges.

Shortened talk time, difficulty holding a charge, frequent need for recharging, and impaired performance may all indicate a need for battery replacement.
