Caution :
8.1 Please charge battery follow the instruction of item 6.1,
charge current cannot be more than the limit of item 6.1 and overcharge with
high current is harmful. It may cause battery deformation, leak or even open
the cover.
8.2 Do not discharge battery to the condition of lower
voltage than 6.4V. Over discharge may decrease the cycle life and may cause
battery deformation, leak or open the cover.
