Charging instructions lithium batteries
Lithium batteries should never be deep-discharged, this damages the lithium cells irreparably. All lithium batteries should always
be stored at medium charge (if possible). If a battery is not needed for a long time, please do not fully charge it before stora-
ge - this puts the lithium cells in unnecessary „stress" 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 it, but always keeping it in the medium voltage range when
in use. Of course, the battery can be fully charged, for example, when driving 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 given in charging cycles. Do not think you „waste" many charging cycles by recharging the lithium
battery more often, even though it is not „emptied" - 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 a half
charging cycle. Twice recharge accordingly means full cycle then.
We recommend recharging a lithium battery when reaching 25% residual charge up to about 75% charge state. Of course,
the battery can be fully charged for long distances - see above.
During the wintering or long storage of vehicles with lithium batteries, it is absolutely necessary to recharge them at least once a
month to about 60% charging state.
For lithium batteries, use only chargers approved and recommended by the manufacturer. Charging with too high charging
current to recharge faster can irreparably damage the lithium cells and in the worst case lead to a fire or explosion.
