• It naturally loses its charge.
• It is necessary to use it several times before its perfor-

BATTERY PACK AND CHARGING PROCEDURE
Appropriate charging environments
For safe and efficient charging, use the battery charger in
a location that is:
• Flat and stable (when on the bicycle)
• Free of rain or moisture
• Out of direct sunlight
• Well-ventilated and dry
• Not accessible to children or pets
• Temperature between 15–25 °C
Inappropriate charging environments and
solutions.
The hot and cold environments described below can
cause charging to enter standby or suspension without
fully charging the battery.
• Summertime charging standby/suspension
• Wintertime charging standby/suspension
• Noise on televisions/radios/computers
If charging in a location receiving direct summer sun-
light or immediately after riding, the battery charger
might enter charging standby (all four battery capacity
indicator lamps flash slowly). See " Reading the charg-
ing status". This is to automatically stop charging in or-
der to protect the battery from exceeding the specified
temperature while charging. You can avoid charging
suspension by starting to charge with the battery cold
or at a room temperature of 15–25 °C. If charging sus-
pension occurs, move the battery charger to a cool lo-
cation to reduce the charging standby time.
Charging standby will occur if the temperature is 0 °C
lower. If charging is started and the temperature drops
below this level due to late-night cooling or other fac-
tors, charging is suspended and standby mode is en-
tered to protect the battery. In such cases, restart
charging at an indoor location with a temperature of
15–25 °C.
Charging next to televisions, radios, or similar appli-
ances might cause static, flickering images, and other
interference. If this occurs, recharge in a location fur-
ther away from the television or radio (such as in an-
other room).
