SOURCE: Can a lithium ion battery be overcharged?

Here's a small FAQ I found: 1) My lithium ion battery is the SONY NP-FP70 Battery Pack. Does the fact that the battery is called a battery pack mean that it has built in circuitry to prevent an overcharge? No. I write with some authority since I've dissected too many and there is no such circuit in the battery. From a system perspective it doesn't belong there. 2) Is there any way of knowing if my SONY BC-TRP charger has the circuitry for preventing an overcharge? You'll have to ask, but the key clues are: a. The documention tells you to not leave it plugged in overnight. b. The battery gets too hot and melts the plastic. 3) If I charge my battery in my camcorder (SONY DCR-HC40), can I assume it has the built in circuitry to prevent an overcharge? a. One can't assume anything. b. But from what I read on that model, you plug it in and forget about it. To do that, it would have a proper charge circuit.

So I had the same problem with my camera. The issue is related to the cracked camera door. The crack protrudes through the large C & E on the bottom of the camera door. When you close the door the negative battery doesn't fully contact the copper node that located on the battery door. The solution I reccomend is to buy a new camera door. If you need a quick fix I would take a small needle & pry up the copper node on the negative side of the battery door. This will allow more contact with the negative side of the battery when the door closes.

Li-Ion batteries cannot be charged efficiently with power supplies or NiCad chargers, they need a pulse charger dedicated to Li-Ion batteries. Also, there is a danger in charging with other sources as Li-Ion batts. will catch fire or explode if not charged properly. Please get a charger that is made for those batteries

Press the reset button and plug it into the charger afterward. The music won't be lost trust me. It just resets the time settings, as well as the music equalizer.
