Buffering (Trickle) mode
General informa-
tion Buffering (Trickle) mode is intended exclusively for relieving the battery during a vehicle
diagnosis or software update. The power used over an extended period of time must be
less than the charger's maximum output current (35 A), otherwise the battery will be
drained. Buffering (Trickle) mode is not suitable for fully charging the battery.

Plug in charger mains plug
Connect battery - the de-energised charger leads mean there are no sparks when
connecting to the battery, even if the charger is already connected to the mains supply.
-
Connect the red charger lead to the positive pole (+) on the battery
- Connect the black charger lead to the negative pole (-) on the battery
The charger automatically identifies the
battery, e.g. 12 V, and starts the buffering
process after 5 seconds.
If the battery voltage is not correctly identi-
fied (e.g. in the event of a deeply dischar-
ged battery), you have 5 seconds to enter
the correct battery voltage, as follows:
If the selection window for the battery voltage does not open, then the battery is in a state
of extreme deep-discharge (less than 2 V). In this case, buffering is not permitted. We rec-
ommend the battery be replaced.
CAUTION! Risk of damage when attempting to charge a faulty battery. Before
buffering, ensure that the battery is fully functional.
Select Buffering mode using the up/down keys.
