New Olympus EM1 Mark 2 won't turn on (Page 2): Exactly, but no guarantee that the new battery arrives charged - probably charged to some extent, but not fully. The only way to sort out...

Exactly, but no guarantee that the new battery arrives charged - probably charged to some extent, but not fully. The only way to sort out whether it’s the camera or the battery is a simple voltage check - just takes seconds, and if it is the camera, then the OP will have an inexpensive and very useful tool for the future.

I've found with Olympus that OEM batteries just won't charge in some non OEM chargers and vice versa.

I'd try a different battery, or charger.., and make sure you're inserting the battery correctly. If nothing else helps it's time to contact Olympus although they are still in the process of adjusting to the new company, JIP, and may not be as responsive until that phase is over? Then there's always the dealer you bought it from which you might contact for warranty service.

The good news is OMDS (90% JIP +10% Olympus) took over all of the repair / warranty. At is time, and for the foreseeable future, OMDS is in the business of warranty and repair.

There are 4 terminals on the BLH-1 battery so which ones would you make the measurement? Besides although the battery is rated at 7.4V would a reading of 7.4V means the battery is good?

Good questions. Without seeing the actual battery, I would expect that two of the terminals are the battery + and - terminals and the other two are an internal thermistor in the pack to sense temperature when charging. I would expect a fully charged Lithium Polymer battery to read 8.2 - 8.4 volts DC. I’d hasten to add that I haven’t used or tested this specific battery so YMMV. Anyone else actually measured this battery?

To turn on an Olympus usually you dress up like a scantily clad naughty Leica and dance around. Ok, seriously though, it seems like the thing is busted. If two known charged batteries do not work then send it back to Oly. (Odd aside, I sent back a malfunctioning 7-14 Pro Oly lens. The manual focus clutch was not working. They wanted about $400 to fix it so I said send it back. It came back repaired. I think they repaired it then sent the estimate. Go figure.)

I don't have the battery either but looking at images on the web it does have the + and - terminals so I guess I would measure there. I make a quick measurement on my EN-EL14a battery which I have used some what and the camera battery indicator shows full the voltage is 7.34V and the battery is rated at 7.2V. So for the BLH-1 which is rated at 7.4V I would expect it to read at least 7.4V open circuit if it's any good.

The problem with batteries is that the voltage under load may not measure the same as when out of camera. This is true with any device depending on batteries for power.

Absolutely true. Although you can infer charge state from the open circuit voltage, you have no idea how the battery will perform under load. From what I can tell, a typical DSLR might draw 250 ma. And twice that when live view is enabled, so for a 7.4 V battery, something like a 30 ohm 2 W (minimum) resistor in parallel with the DVM leads would make a nice load for testing.

Even so, I doubt the battery would fail in a matter of seconds with an indicated full charge if something weren't amiss.

I've never had this problem. I use a Watson charger and it works fine. And I use only OEM batteries
