- Hello everyone-
- I have a Futaba 6 channel FM transmitter, two years old. It has been
- lying idle for the winter, and now that weather is (well, hopefully!)
- getting warmer again, I brought it out of its slumber...
- My question: The battery was very low, and so I plugged the unit and
- the transmitter battery pack into the factory supplied recharger
- overnight. Ofter about 24 hours of recharging, the voltage on the
- transmitter pack read at about 5.6 V, according to my Tower Hobbies
- voltmeter (top of the "green" scale). However, the transmitter pack read
- at only 9.5 V, which is rather low (the low end of the "green" scale).
- Also, the voltmeter on the transmitter read only about 80%. When the
- unit was new, the voltmeter read above 11 V, and the scale on the
- transmitter read above 100%.
- Is my batter dead? Can I fix it? Or should I just get a new battery.
- Is this the expected life?(two years)?
-
- Any opinions welcome,
- Mike Muller,
