Battery Chargers Failures

It all started with my field box battery. I seemed to be getting worse and worse and I always put it on charge after flying. I brought it in from the garage and took the field box apart so I could take the battery out. It is one of those smaller batteries for an ATV. They are small and light and designed to be used with a starter. I put the usual charger that I use on it and left it over night. It was still flat the next day. Just for the hell of it I put one of my other chargers on it at .5 amps for about an hour. The voltage came right up. I pulled the caps of it and topped it up with water and put it on low charge for 24 hours. I tried it with several long starter runs and it seemed to work fine. I check the output on the charger I was using and it was dead. I should have known when I pulled it out of the wall it was stone cold. I have always had trouble with Futaba chargers. I checked both voltages on all three. They ran from poor to unacceptable. What about my glow starter chargers. I found one of them completely dead too. That was the one with no light on it. I checked the voltage on the Futaba chargers with a battery attached. Not one would rise above the voltage of the battery. A couple of notes. I pried my field box charger apart and both diodes were open circuit

1. In a Futaba transmitter the first thing the positive lead goes through is a diode, this diode will use up .7V. So make sure that your charger is putting out enough voltage to fully top up the battery.

2. Most Futaba chargers will not put out enough voltage to charge an 6V airborne battery.

If you have not checked these lately it might be a good time to spend some time on them.

Re: Battery Chargers Failures

Thanks for the info on Futaba chargers I do not have one and now I know I will not have one.
