Hi, this is the second brand new battery (BV5JW I buy for my N9 but when I replace it, it won't charge. So the residual juice that comes in the new battery eventually dries out and it wont boot or charge again.

Clearly, it is not a problem with the new batteries being defective, as they were bought from different places, however my N9 does not want to recognize the new ones for some reason. When I put back the old one, it boots and charges normally.

I feel like I am being very stupid in here but I looked for other threads and I could not find anything related to my problem other than this one. Any idea of what is going wrong? Has anybody replaced their battery in their N9 successfully?

by the way, I tried the methods recommended in this post, but none of the work.

Thanks
