Wasabi Power 7.6v 1300mAh Dedicated charger.
Progo 7.6v 1600mAh chipped uses Olympus charger.

Given the Hänel's much lower spec. capacity than the Progos, but better
practical performance, it seems even more likely
to me that the Progos don't communicate properly with the camera.

As Chuck pointed out, they are a slightly different chemistry, so that could be
the reason. Mine are all 7.6v and have
no noticeable short turn storage discharge problem.

They apparently aren't sold here. There are a few of their batteries, but
nowhere near the whole line, and not including
the one for the E-M5. Also not much cheaper @ £30, vs. $55 US. At $11, the
Progos are away less expensive per shot.
