[QUOTE="nickt, post: 201353, member: 4923"] It was probably time for it to go. While it's not a good idea to drain every last drop of power from the battery every time, it won't kill a good battery. But it can put an already failing battery out of it's misery. The camera shuts down before it gets to the point of hurting the battery. There are strict protection circuits in lithium ion batteries because they tend to rapidly vent with flame if not treated well. Your camera probably ran the battery down and then shut itself off. The battery then self-discharged even further because it was not in good condition. It got to point where the protection circuit decided it was unsafe to allow the battery to charge. You might have pushed it over the edge, but it was probably heading for failure anyway. [/QUOTE]
