CHARGING INSTRUCTIONS FOR LITHIUM BATTERIES
18
Lithium batteries should never be deeply discharged, this damages the lithi-
um cells irreparably. All lithium batteries should (if possible) always be stored
at medium charge. If a battery is not needed for a long time, please do
not fully charge it before - this puts the lithium cells in unnecessary „trouble“
which in the long term can lead to a shortened life. If you have the choice
when using the battery, we recommend in principle not fully charge, but
always in the medium voltage range to use. Of course, the battery can
be fully charged, for example, to drive long distances - it is only technically
for a lithium battery the best, not to do this to really get the maximum in
performance and life out of the battery. The life of lithium batteries is gi -
ven in charging cycles. Do not think you „waste“ many charging cycles by
recharging the lithium battery more often, even though it is not „drained“
- this is completely wrong! For the specified life in charging cycles so-called
full cycles are meant. This means that if you discharge your battery by 50%
and then recharge it fully, this equates to ½ charging cycle. Charge twice
a full cycle accordingly. We recommend recharging a lithium battery with
25% residual charge up to about 75% charge state. Of course, the battery
can be fully charged for long distances - see above. During the wintertime
or long storage of vehicles with lithium batteries, it is absolutely necessary to
recharge them at least once a month to about 60%. For lithium batteries,
use only chargers recommended by the manufacturer. Charging with too
high a charge current to recharge faster can irreparably damage the lithi-
um cells and in the worst case lead to a fire.
