A:AnswerI've noticed this also. Sometimes the charger turns green, sometimes it stays red. I've only had this camera about a month, I'm going to see how long the charger takes to turn green (when it happens) and just set a timer and take the battery off the charger when it reaches the "green" time.
My old Olympus charger used to do this too, BUT it was 15 years old :)
A:AnswerIf using canon charger CB-2LF, until charger changes from amber light to green light. New uncharged battery can take up to two hours. Recharge depends on level of discharge.
