Lasts half the time of an Olympus battery
on 29 September 2017
I have an Olympus EM-1 and wanted a spare battery to take on shoots with me. I nearly fainted at the price of the Olympus batteries, so when I saw this was compatible I gave it a go. I am sorely disappointed. Having now given it several full discharges and re-charges it only lasts half the time of my Olympus battery. I shoot wildlife and often leave my camera on for longish periods while I'm waiting for action to happen. My Olympus battery will go for approx 4 hours with a mixture of just powering the camera plus shooting, whereas I'm lucky if I get 2 hours out of the Ex-Pro. I'll keep it as a last-resort backup battery but will be digging into my piggy bank and replacing it with an original Olympus.
