Bundle Star Patona Battery for Olympus BLN-1 PS-BLN-1 (real 1050mAh) with Info Chip (latest generation 100% compatible!) To Olympus OM-D E-M5 E-M1 and OM-D E-M5 Mark II (Electronics)
I do not use the battery with my Olympus E-M1. I had previously noticed neither problems while charging the battery with the original charger still has the power uncomfortable.
