6.17 The battery system
WARNING: Use only original batteries
recommended by the manufacturer. Product
safety cannot be guaranteed with other
batteries. Do not use non-rechargeable
batteries.
The battery is considered to be fully charged when the
battery reaches 80% of the total capacity. To charge the
battery to 100% would take too long since the charging
current is low. The most rational way of using Li-ion
batteries is therefore to stop charging at 80%. The
maximum utilised capacity is thus 80% of the battery’s
total capacity.
The battery is maintenance-free, but has a limited life
span. The battery is expected to last for 3000 - 4000
charging cycles. The normal charging current is 7 A.
