I bought a Sony FV-100 Battery knock-off for my CX130e (I'm not gonna pay $189 for a battery..) But the weird thing is, after about 2 hours of charging the light on the camcorder goes out so it's "Full" right? As soon as i dive in the menu and check "Battery info" It has almost all the blocks full apart from one (So let's say about 75% Charged) So now i've plugged it back in the camcorder, and here it is charging again for 15 minutes already. Battery is 2 days old now, and it has been fully charged and discharged already once. If someone could help me with this i would be grateful I've also read something about having to charge it from empty to full for atleast a few times for the camcorder/charger to calibrate or something? Since it charges for 2 hours and then the light goes out, and after that i can plug it out and in again and it charges again for some more time. (So maybe the charger can't handle this much of a charge at once? Since it's 3900mah) So yeah, thanks in advantage!
