Push button, the LEDs light up. Information about the bat-

of LEDs that light up and the way in which they light up.

5 LEDs flash quickly
1st LED flashes quickly Charging fault **
* All five LEDs flash quickly: The battery is empty and is
being switched off, or is overloaded.
• 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.
• If the battery is overloaded, it will switch back
on after a short idle period and can then be used
normally.
** The first LED flashes quickly: A charging fault is present.
• In that case, please remove the mains plug from
the socket and then plug it in again after a short
time. The charger performs a readjustment. In most
cases, this rectifies the fault.
• If the LED continues to flash, overheating or under-
cooling of the battery may also be the cause. If, for
example, you charge the battery in a cold environ-
ment at a temperature below 0°C, or the battery
heats up to over 60°C during a long ascent, the
management switches off to protect the battery. In
such cases, the battery must be taken to a warmer
environment or cooled down.
• If the LED still flashes, take the battery to your
specialist cycle shop and have it checked.
