Lt. Print is the battery capacity slightly less than the Oly-original in minimally higher voltage. But what are already numbers and who checks the after? Practice is one and after a few charges remains to note that the Ansmann keeps just as long and the same time to load required as the original. The power consumption of PENs is not without and thus you feel better without two- or third battery out of the house if you want to shoot a few more pictures and a retrofit of the Ansmann battery is just right.
