Care
How to increase the service life of the battery
The Bosch battery is an important component of the eBike. With the
correct handling and care, its service life can be lengthened.
Cleaning & care
A damp cloth is recommended for cleaning
the battery. Plug connections should be
cleaned occasionally and lightly greased.
The battery should be removed before clean-
ing the eBike. To protect the electronic com-
ponents, the battery must never be cleaned
with a direct jet of water or high pressure hose.
Storage during winter
Store the battery in a dry location at room
temperature. Fully charging or fully discharging
results in higher loading of the battery. The
ideal charge status for lengthy periods of
storage is approximately 30-60% or two to
three LEDs on the battery indicator.
Winter use
During winter use, particularly below 32°F (0°C), charge and store the
battery at room temperature and insert it in the eBike immediately before
a ride. For longer journeys in cold conditions, use thermal protective covers.

Service life
Tips for maximizing your charge
The service life of Bosch batteries is influenced mainly by the type and
duration of use. Like every lithium-ion battery, a Bosch battery also ages
over time, even if you do not use it. Over time, it loses capacity.
Factors that shorten the
service life:
▶ Heavy-duty use
▶ Storage at more than 86°F (30°C)
ambient temperature
▶ Prolonged storage in below 32°F (0°C)
charged or fully discharged state
▶ Exposure to direct sunlight
▶ Regular complete discharge
of the battery

Age/charging cycles
Factors that extend the
service life:
▶ Low load
▶ Storage at temperatures
between 32°F (0°C) and 68°F (20°C)
▶ Storage at approximately 30-60%
charge status
▶ Storage in a shaded or cool location
