i have 1200mAh. 3,8V asus a400cg battery combine with my 2200mAh. 3,8V lenovo battery. it work well!! 8hours last for nonstop activities, before then it just last for 3-4hours only.

next day, i accidentally short-circuited my lenovo battery. does it reduce the battery current power??

now it feel like im using 2000mAh power only ;(
