Olympus BLS-5 Lithium Ion Battery for E-PM2, E-PL2, E-PL5, E-P5 & D M10 (accessory)
I've ordered for my vacation a spare battery. The price is very high, but I did not have much confidence in a no name product. The batteries last very long in the Olympus Pen E-PM1. Delivery was very fast and the battery came in original packaging -
