I wanted to know, can Lithium Ion batterys such be overcharged?
Normally Lithium Ion batteries will not be overcharged if you use the correct charger and follow the manufacturers recommendation. Most systems have monitoring circuits to prevent overcharging and overheating. The Sony “InfoLithium” batteries and some of the Canon batteries have the circuitry necessary to monitor the battery as part of the battery. It it not normally NOT a good idea to discharge Lithium Ion batteries. Just charge them as the manufacturer recommends. Q:I understand that I can leave it on the charger, but what about partially charging it?Like if I were to charge a battery that still has power in it ex. 5 hour battery capacity, only 2 hours used, will the battery or camera know when to shut off charging to prevent possible overcharging? A: Yes, the battery/charger will know when to stop the charging. The Power/Charge lamp will blink when charging starts and when it has has completed the charge the Power/Charge lamp will go out. The charging time will depend on the current
