Sony Lithium Ion Battery does not hold a charge over a period of time?
I have a Sony Cybershot camera that i got about 10 months ago. Recently the Lithium Ion battery that it uses (Type G) will not hold a charge over a period of time. If i charge the camera and then i don’t use it for 4 or so days the battery will be completely depleted and i have to charge it again. Should i just buy a new battery? Is anyone else having a problem similar to this?
You just got stuck with a bad battery, take it in and get a new one.
