Especially never connect LiPoly cells in parallel*. They are typically above 3.7V but above or equal 4.2V when charged. If the cell is too low it won't charge, or will only charge very slowly.

Keep screen and any ribbons.


I checked that both had a similar charge of 3.8V, and adding amperes, about 2800mAh. I connected them just to see if they would turn on the e-reader... but it didn't.

Thanks for the reply

It is not just the RATED voltage to consider. it is the current 'terminal' voltage.
