REpairing DV camcorder batteries??
I've got some DV camcorder batteries.
Canon BP-511's for the ZR series of miniDV. They refuse to take a charge. I cracked one open and tested the cells. They carry a charge. They batteries do have a small circuit card on top that is likely the problem. The card has a couple of IC's a few resistors/capacitors. I realize that it'd be difficult to replace components on this card but has anyone here done any work on these? Here are a few numbers from the battery. The circuit card has E 1571 imprinted on it. There are two battery cells(Li-ion) made by A&TB. LGR18500P AD30A They meter out at a total of 7.1 volts. The pack is normally rated at 7.4 output.(this battery pack was about half down when it suddenly quit.) Thats straight of the poles. Dead at the out terminals of the circuit card. Correct me if I'm wrong but I'm thinking the primary function of this circuit is the regulation of the charge rate to the batteries and shouldn't be needed to run juice to the camera from the batteries per se. I use a belt battery pack most of the time with my camera but hate to see the oem battery go to waste. Can anyone give me any info on these batts? TIA |
