The battery box should be stored fully
charged in a dry and cool place. Remove
the plug of the battery cable from the box.
All batteries are shipped with an additional
documentation about the last charging
date within our SRAM facility. This
documentation of battery charging also
allows you to fill in the dates of additional
charge actions that you would need to
perform if the batteries stay in your
warehouse over a longer period of time.
You can identify the next necessary charge
date at a glance (at least 3 months after
last charge).

• Insert the plug of the charger into the
socket of the battery box.
• Insert the charger into an electric mains
socket.
The LED will glow red during charging,
changing to green when the battery is fully
recharged.
When not in use always withdraw the
plugs from the socket and the battery box
Caution:
• Recharge the battery at least every 3
months.
• The battery must only be charged in a
temperature range of +5°C to +30°C.
• Only charge the battery in the operating
position.
• Only use in dry internal areas.
• Do not use in rooms (garages) with an
explosion risk.
• Do not dismantle the charging unit and
battery box yourself.
Incorrect assembly can lead to
electric shock or fire.
• The charging unit should not get into
the hands of children.
• Charging should only be carried out in
sufficiently well ventilated areas.
• When not in use always withdraw the
plugs from the socket and the battery
box (do not pull on the cables).
• Regularly check the cable and protect it
from sharp edges. If it is damaged have
it renewed immediately by a specialist
workshop.
• Protect the unit from oil, grease,
aggressive cleaning agents and paint
thinners since they can destroy the
housing.
• If it falls, from a bench for example, the
unit must immediately be given a safety
check by a specialist workshop. This is
also necessary if contact pins become
loose.
• The battery must never be burned. Risk
of explosion!
• The battery must be disposed of accor-
ding to the waste disposal regulations.
• Only ever use the right Sparc charging
unit with the corresponding Sparc bat-
tery.
