Over discharged battery, any advice?

mookster · 02-11-2010, 11:53

Hi to all.
I have been having a few problems with my D2. It is a DAB version with 1.11 D2+ firmware. It was working fine up until recently, when I was having problems charging it, and would have to plug it into my PC, then into the wall charger, to get any life into it.
Today I took it apart, and tested the battery, which is showing 2.4V. Not good. I'm pretty sure it should not be able to go below 3V, and the tricks I was doing to get it to work were discharging the battery below its normal threshold.
Basically, does anyone know if there is a way of recharging a LiPo from below 3V? I've tried plugging it into the wall charger overnight, but it doesn't seem to do anything.
Thanks in advance for any useful advice.

I have no idea if you can rescue the battery.
You have your D2 already taken apart, so why don't you just put there a new battery as described in this thread:
