Hello everyone, Help. I have an LC-E4 battery charger. Yes I know it has been replaced by LC-E4n but do not need that. Just want to know what the three buttons on LC-E4 charger do as I do not have the manual with it. One is in the middle Calibrate performance, do I need to and how often? Other two are individual to each battery placement and just say cal (in red) charge (in green) Also one of the LP-E4 batteries died can anything be done with it other than off to the recycle heaven? Got a new replacement LP-E4N, £160, ouch and it does charge to 100% in the old LC-E4 battery charger.
