5 LEDs flash quickly
1. LED flashes quickly Charging fault **
* All 5 LEDs flash quickly: The battery is empty and is
being switched off, or is overloaded.
› If the battery is overloaded, it will switch back
on after a short idle period and can then be used
normally.
› If the battery is empty, it will work once again
briefly following a short period of rejuvenation and
will then switch back off. It must now be charged.
** The 1st LED flashes quickly: A charging fault is present.
› If this occurs, put the battery in the docking station
for a short period of time or insert the plug of the
charger into the battery. The charger performs a
readjustment. If the LED still flashes, take the
battery to your specialist cycle shop and have it
checked.
