Status: offline 		I have noticed that my "reliable..always watched closely" batteries in my TX and RX have shown abnormal volts compared to what I was always used to seeing. I charged the batteries.....checked them with my loaded digital voltmeter, but left them plugged into the charger. The charger is on a TIMER so the current WAS OFF. (in fact..I had pulled the timer out of the outlet this time) The batteries were at full charge. I checked them a little less than 24 hrs. later. They had dropped much more than I was used to seeing. EXAMPLE: My RX was at 5.35 volts and it had dropped to 4.90 volts. (about what I might see after 4 flights). My TX dropped to 85%+ on the meter, from it's "pegged" position!! My question is this..... Has
anyone out there experienced this problem with the Hobbico Muli-charger described above??
Is it possible for the current to "drain off, or back" through the charger due to design flaw, or a malfunction??? ... thanks ... lownslo

And the Hobbico Multicharger and AccuCycle were one of them. I actually tested this a while ago, and found that they do take out a significant amount over the couse of a week or so. [SIZE=1](Red, you might recall this, as I send you the findings in an e-mail about 2 or 3 years ago. [/SIZE]

I routinely unplug all my batteries from chargers now if they are to be disconnected from the power sources.

Status: offline 		Thanks to you both !!! I sort of thought that might be happening. It sure would help people out if the manufacturers would mention unplugging the battery if the power source is shut off. ....lownslo
