A77 and 3rd party battery. Help!
Please consider this as request for help as well word of caution.
I was an early adopter and puchased my A77 kit (SAL1650) 4 weeks ago. Tomorrow morning heading to Rome and as preparation I have purchased two extra batteries, one original Sony and one Hähnel HL-XM500 along with Hähnel PowerStation Twin V Pro, which can charge two batteries independently.
Just a moment ago I faced totally unexpected proplem: I can't get this Hähnel battery out of A77. Originals are come out smoothly, but not this one. My nightmare is now am I bound to survive my Roman holiday with one battery only. My previous experience with R1 and battery life by my style of shooting asks for spares.
I wonder if anyone have faced similar (physical) problem, myself never with my R1 either.
EDIT: After all I managed to get out the battery. Tested with the original, and once again: Sony pops out easily .
I bought the same Hahnel battery and had exactly the same issue as you so have sent it back. I also found it only charged up to 70%.
It's a shame because I've used Hahnel batteries before and found them to be just as good as the Sony batteries only half the price.
I remember having read about this charging level issue before I charged my second Sony and this Hähnel, so after simultaneous charging on the Twin V Pro I checked both on A77 and it did not display any difference on level. Unfortunately i put in first Sony and then Hähnel. Otherway round and I had noticed this problem in time before my trip (for possible return).
A closer look at these two batteries on their bottom shows that on Sony the contacts are closed while Hähnel has open slots on all the three. If one looks inside the battery chamber of A77 there are two flat contact(sensor?) areas on bottom, next to the coil spring. Makes me worder their function...

Vertical grip contacts.
Thanks for explanation.
