This camcorder has been working fine but suddenly without warning a couple of months ago the battery went flat and I was unable to recharge it. I took it to Currys and they checked out the camcorder, battery and recharger and said it was the battery. I purchased a new battery but this has now run down and again, it will not recharge. The camcorder runs fine from the charger but not alone as the battery will not recharge once run down. Is this a common problem? What could have caused it? Is there any way it can be rectified other than buying a new battery every time the old one discharges.
