Quick Answer
For portable VHF/UHF radios, lithium-ion batteries and lead-acid batteries are the most suitable options due to their efficiency, reliability, and compatibility with the radios' power requirements.
Choosing the Right Battery
When selecting a battery for a portable VHF/UHF radio, it’s essential to consider the radio’s power requirements and the battery’s capacity, depth of discharge (DOD), and recharge characteristics. A lithium-ion battery with a capacity of 2000-3000mAh is a good starting point, but for larger radios or extended use, a 4000-6000mAh battery may be necessary.
Battery Characteristics
Lithium-ion batteries are the preferred choice for portable VHF/UHF radios due to their high energy density, long cycle life, and low self-discharge rate. They can be charged and discharged multiple times without losing their capacity, making them an excellent choice for ham radio operators who need reliable power on-the-go. When selecting a lithium-ion battery, look for one with a high discharge rate (e.g., 10C) to ensure it can handle the radio’s power requirements.
Maintenance and Safety
To ensure the longevity of your lithium-ion battery, keep it away from extreme temperatures, and avoid overcharging or deep discharging. Regularly clean the battery contacts and terminals to maintain a good connection with the radio. For lead-acid batteries, follow the manufacturer’s guidelines for maintenance and use, as they require more maintenance than lithium-ion batteries. Always handle batteries with care, and store them in a protective case or bag to prevent damage.
