This has probably been addressed before, but the I can't get the frustrating search function on this otherwise excellent forum to find it: I have an almost new E-P3 that came with a BLS-1 battery and BCS-1 charger in the kit. The previous owner added a second battery to his order, and J&R sent him a BLS-5 (but no BCS-5 charger). I have seen various unexplained cautions against charging the -5 batteries in -1 chargers, but only after I had already done that a couple of times (and it worked fine, BTW). Does this mean I have to either buy an older out-of-date battery and throw away the new BLS-5? Or buy a BCS-5 charger and carry around two chargers? Or, if I buy a BCS-5 charger, is it compatible with the orginal BLS-1 battery?
