- Don’t try to run your Baofeng UV-5R on AAA batteries. It just doesn’t work out well whether rechargeable batteries or high-quality alkaline batteries…it just doesn’t work. In three separate tests I never got more than 1.5 hours of radio run time out of the Energizer 850mAh rechargeable nickle metal hydride batteries. And that meant no heavy transmission time.
- I got just under 3 hours of run time on Tenergy 1000mAh rechargeable nickle metal hydride batteries.
- The AAA battery tray works just fine and fits well without any modifications.
So, the bottom line is…only use AAA batteries when you don’t have any other battery option available.
What my testing showed for AAA batteries:
- AAA batteries just don’t have enough power to keep the radio running for very long. Even with the best of the AAA batteries, 3 – 5 hours of run-time is just not adequate. Well, unless there simply is nothing else available.
- Rechargeable AAA batteries suck. Energizer AAA rechargeable batteries really, really, suck.
- Alkaline batteries are marginally better. But only marginally better.
What my testing showed for AA batteries:
- AA batteries (the big brother to AAA batteries), are exponentially better for radio operations. They lasted 5 – 8 times longer their smaller counter part.
- Rechargeable AA batteries are also acceptable for using in radios, but only quality rechargeable batteries such as Tenergy or Duracell. Energizer rechargeable batteries are worthless.
- Running my UV-5RA on Duracell alkaline batteries (5 to start with a dummy battery to prevent over voltage) I was able to get 38 hours of operation. When the radio shut down I swapped the dummy battery for a brand new Duracell and got another 1.5 hours of radio operations out of it.
I won’t ever depend on Energizer AAA or AA rechargeable batteries. Energizer batteries suck…period.
