BQ Tesla Battery Replacement

I want to replace my tablet BQ Tesla battery, because the old one has swell.
The tablet had 2 batteries inside of 3.7v each one.
I thought if I bought only one 3.7v battery it would work, but the tablet does not turn on with that battery.
The tablet turns on without any battery.
After googling a bit I'm thinking that I got the wrong battery.
Can someone help me understanding which battery will work?

Thanks in advance

EDIT: The 2 batteries have each one a red and black wire, so I think are in parallel, right?
