11. Troubleshooting
The charger is very user-friendly thanks to the menu navigation and plain text displays. However, problems may occur,
which are detailed below, together with possible remedies.
Make sure that all charger settings you have made exactly match the connected rechargeable battery!
Check the connection between the power supply and the charger for problems (cuts or other cable damages). Fur-
thermore, you should check that the charging cable connectors are intact and not undersized. This can often be
recognised by excessive heat. The charging cables should not be longer than 30 cm with a minimum conductor cross
section of 2.5 mm².
When operating with a car battery, make sure that the connectors are properly connected to the battery poles. Many
charger related problems are due to problems with connection cables and terminals.
Try charging another rechargeable battery; the rechargeable battery might be in poor condition and cause problems.
Try charging a different rechargeable battery type. For example, switch to a NiMH rechargeable battery if you have
problems with lithium cells. If you also experience problems with the other rechargeable battery type, the charger
could be defective. Check everything again very thoroughly.
Contact our service, provide full details and a description of the problem, including the type of power supply, recharge-
able battery and number of cells.
If a connection problem is displayed, make sure that all rechargeable battery connections are properly set up. Speci-
cally check the balancer connection. If everything is ne, clean the connector contacts to remove oxidation. Make sure
you use a high-performance switched-mode power supply or a fully charged car battery with a high capacity value.
Try charging another lithium rechargeable battery from another manufacturer, preferably with a different balancer
connector system, to exclude any possible errors.
Never attempt to tamper with the device, as it is too dangerous and will automatically invalidate any warranty claims!
Repairs should only be undertaken by qualied personnel. Improper repairs can cause res and/or electric shocks.
Send the charger to our service for repair.
