Frequently Asked Questions

AI
Rechargeable Li-ion or Ni-MH batteries are better for frequent use and professional walkie-talkies to reduce waste. Alkaline batteries are ideal for emergency radios that sit unused for long periods, as they typically have a longer shelf life.
Check the model number of your radio and the specific battery part number (e.g., PMNN4477AR). Ensure the voltage (V) and capacity (mAh) match or exceed the original manufacturer's specifications.
Voltage (V) is the electrical pressure and must match your device's requirements to function. mAh (milliampere-hours) represents the capacity; a higher mAh rating generally means the battery will last longer on a single charge.
