The battery is the original Olympus Charger (BCM-5) of the E-5 is not recognized (the charge indicator light does not light up). In addition, (Olympus E-5), the battery charge status is not displayed in the camera. So he is not as advertised "a perfect replacement for your original battery" but can be used for the Olympus E-5 not use. Whether it works with the other being surrounded Olympus E-models I can not say.
At least it gave the return at their own expense, refund the purchase price from the supplier M & L Mobiles.
