CHARGING INSTRUCTIONS FOR LITHIUM BATTERIES

Lithium batteries should never be deeply discharged, this damages the
lithium 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 „trou-
ble" 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 technical-
ly 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 given
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 specifi ed 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 lithium cells
and in the worst case lead to a fi re.
