I'm having problems getting my 2450mAh battery to work well..
before doing as Estel explained in http://talk.maemo.org/showpost.php?p...&postcount=846 I had 1299mAh charge
and after first cycle I got 1311mAh, 12 mAh with one cycle.. total goal about 1000mAh, far from two cycles..
Any ideas why so low increase?

I had loopmode=5 running for whole time (about 2 hours) while I used webbrowser to drain battery quickly.

bq27200.sh during charging before
