How many times can you recharge a digital camera lithium battery?”
In general, lithium batteries may be charged hundreds of times, although they are pretty particular about how they’re charged, so it’s really best to charge them only in the charger they came with. Other thing I’ve found with mine is that their useful life is typically only about two years or so.. If a lithium battery is discharged too much, it may be damaged, likewise, one does NOT want to over-charge a lithium battery! Chances are good that your batteries may be nearing their end of life. Remember to send them to a battery recycling depot; they’re considered hazardous waste, and can’t go into the trash.
