During the charging process (Fig. 9.4), the diode on the charger will glow red (1). When the battery is fully charged,
the diode on the charger will turn green (2).
CAUTION: If the red diode flashes during the charging process (3) a charging error has occurred.
In that case, remove the charger from the socket, discontinue use of the motor support and
contact your Authorized Specialized Retailer.
INFO: The Battery Management System (BMS) is designed to protect a fully discharged battery
from damage for a period of time. However, in order to maintain the best possible battery
performance and lifespan, Specialized recommends regularly recharging the battery to at least
60% full (7 LEDs on the TCU).
INFO: Please note that Li-ion batteries gradually lose capacity depending on age and use. Strongly
reduced operating time after fully charging can be a sign that the battery is reaching the end of
its useful life and has to be replaced. Provided the bicycle has been used properly, approximately
75% of the battery's original capacity should remain after 300 charging cycles or two years.
Replacement batteries can be purchased from your Authorized Specialized Retailer.
The charge level of the battery is permanently displayed during your ride. The number of LEDs glowing BLUE
indicates the remaining battery charge (Fig. 9.5). When the battery charge reaches 10%, the last LED will glow
RED (Fig. 9.5).

At 15% - 20% battery charge remaining, the system will start to reduce the amount of motor support to ensure
continuous assistance at lower charge levels. At 3% - 5%, the system switches off motor support, leaving the
bicycle powered on. This not only supports battery health and lifetime, it also allows you to keep wired lights
powered for about 2 hours.
The actual state of charge to trigger motor shut-off can deviate from the norm, depending on some variables like
