F) RECOND: Charging program with higher end- of-charge voltage and constant
current charging, used only for restoring the charging capability of lead acid batteries
which have undergone exhaustive discharge. Not for AG
The RECOND process must be checked every half an hour and must never exceed a time
of 1,5-2 hours. Refer to the instructions supplied by the battery manufacturer.
џ Gassing generates explosive gas - risk of explosion! Ensure that there is good
ventilation.
џ Only use the RECOND program for lead acid batteries and only as described below.
Take care to avoid spilling any battery acid. Battery acid is aggressive. Read and
observe the safety information.
Warning!
џ Never use for a battery which is of sealed design (VRLA battery such as, e.g. AGM or
GEL battery). Refer to the instructions supplied by the battery manufacturer.
Using the RECOND charging program
џ Connect the charger to a lead acid battery as described in section 5.3 and check the
charging process every half hour.
џ After 2 hours at the latest or as soon as the battery starts audibly gassing (bubbling),
remove the charger as described in section 5.3.
џ If possible, check the acid level and, if possible, top up the battery cells, if necessary
just with distilled water. The acid level should ideally be between the marked max.
and min. level and should be identical for all the cells. Screw the battery stoppers, if
there are any, tightly in place.
H) SUPPLY: For supplying 12V d.c. voltage, e.g. when changing a battery or for operating
12V d.c. consumers.
Press the “Mode” button -> switch from the RECOND to the SUPPLY function.
Warning! Protection against swapped poles will not be available. If the poles are
swapped there is a risk of damaging the charger and the battery/ on-board vehicle
power supply or a connected consumer. It is imperative that you make sure the polarity
is correct when you connect up. Observe the maximum power consumption (see
“Technical data”) of the consumer.
Note:
џ Only use for batteries which are free-standing and have been taken out of the car,
not while installed in your car with a connection to the car's electrical system. The
higher charging voltage could damage the electrical system.
џ The direct voltage which is provided (shown in the display) is load-dependent and
without load it is approx. 14.5 V.
џ This function can be used for consumers which are operated from a vehicle's
cigarette lighter.
џ Refer to and observe the operating manual for your 12 V consumer.
