As mentioned in a previous post, I’ve been mulling over battery options — partially because OEM batteries are fairly expensive, and partially because some 3rd party options have potentially attractive additional features.
I’d gotten busy with regular life activities, and almost forgotten about my promise to do some testing, when I ran across this interesting video on YouTube. In the video, a Finnish gent tests an OEM BLH-1 battery and some 3rd-party replacements for it, using an OM-D E-M1 camera. I liked his approach, with a few provisos — namely, that I think using the internal intervalometer was causing him some of his issues (camera stops recording before the battery is fully discharged, residual charge level varies from battery to battery).
