There are a number of threads about batteries for the OMD and how quickly they need to be recharged when being used. My wife is going to speak at a meeting at the college that we met at tomorrow. So, we are going to make a day trip out of it and I decided to recharge a battery that has been in an "off" camera for a few weeks. It is taking as long a full recharge. It is not SD cards that I worry about carrying, it is batteries.
