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,
