solar power charging of 8890 battery
Has anybody tried charging their 8890, with the BLB-2 battery on board ?
I understand that the BLB-2 has a 750 mAh output.
In good light conditions my solar panel outputs 290mA, which triggers the normal charging response from the screen as one sees when charging from mains AC.
In not so good light the 8890 screen does not change.
I am trying to establish if the battery is charging, but the screen does not respond or if it is not charging at all ?
Additionally, I guess their might be a cut off on the phone software that says if a charge of less than x mA is received, do not charge. If so, what is this number ?
Does anybody have any ideas where I might go to get the answers ?
