Question about Sharp Viewcam VL-NZ100U Mini DV Digital Camcorder
I've left my battery connected to the Sharp Camcorder VL-NZ100E for a few months and decided to use it again- i forgot to remove the battery from the Camcorder Tried to charge the battery but it doesn't seem to charge-the battery should feel warm after at least 1 hr but it doesn't. The Camcorder can power on with power adapter connected but not with battery How do i confirm if its a battery failure or the charging circuit in the Camcorder is faulty? I can easily buy the battery if its a battery failure.I do not intend to send for repair if its a charging circuit failure. I've tried measuring the two leads in the camcorder which connects to the battery round contacts with the camcorder connected to power adapter to ground and found it to be about 2.7V Does this confirm if the charging circuit is ok? I've tried to clean the battery round contacts and the two leads in the camcorder but the battery still did not seems to charge Appreciate your advise.Thanks

2.7 volts is too low. Usually camcorders use battery at least 6 volts. Problems with rechargeables especially NiCds and NiMH, a cell will be shorted. for 6 volts pack, there are 5 cells in series (5 pcs x 1.2 volts with load , 1.35 no load). If you are measuring only 2.7 volts, it is highly possible that 3 cells are dead. As for the charger, if the same charger is used to power the camcorder and you said the the camcorder operates using the adaptor, this means that the charger is OK. You can ZAP the battery back to life but I will not recommend. It can be dangerous. If you can buy the battery, I suggest you do it since the old battery, even when zapped, will not provide enough juice anymore.
