11. PERSONAL PRECAUTIONS
a) Someone should be within range of your voice or close enough to come to your aid
when you work near a lead-acid battery.
b) Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing,
or eyes.
c) Wear complete eye protection and clothing protection. Avoid touching eyes while
working near battery.
d) If battery acid contacts skin or clothing, wash immediately with soap and water. If acid
enters eye, immediately flood eye with running cold water for at least 10 minutes and
get medical attention immediately.
e) NEVER smoke or allow a spark or flame in vicinity of battery or engine
and
NE JAMAIS FUMER PRÈS DE LA BATTERIE OU DU MOTEUR ET ÉVITER TOUTE
ÉTINCELLE OU FLAMME NUE À PROXIMITÉ DE CES DERNIERS.
f) Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or
short-circuit battery or other electrical part that may cause explosion.
g) Remove personal metal items such as rings, bracelets, necklaces, and watches when
working with lead-acid battery. A lead-acid battery can produce a short-circuit current
high enough to weld a ring or similar metal items, causing a severe burn.
h) Use charger for charging a LEAD ACID battery only. It is not intended to supply power
to a low voltage electrical system other than in starter-motor application. Do not use
battery charger for charging dry-cell batteries that are commonly used with home
appliances. These batteries may burst and cause injury to persons and damage to
property.
i) NEVER charge a frozen battery.
12. PREPARING TO CHARGE
a) If it is necessary to remove battery from vehicle to charge, always remove grounded
terminal from battery first. Make sure all accessories in the vehicle are off, so as not to
cause an arc.
b) Be sure area around battery is well ventilated while battery is being charged. Gas can
be forcefully blown away by using a piece of cardboard or other non-metallic material as
a fan.
c) Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
d) Add distilled water in each cell until battery acid reaches level specified by battery
manufacturer. This helps purge excessive gas from cell. Do not overfill. For a battery
without cell-caps, carefully follow manufacturers recharging instructions.
e) Study all battery manufacturer‘s specific precautions such as removing or not removing
cell caps while charging and recommended rates of charge.
f) Determine voltage of battery by referring to car owner‘s manual and make sure it
matches output rating of battery charger.

5) Operation Mode
5. a) SUPPLYMENU – for power supply mode
Parameter Nominal value Value / Setting range / Information
Output voltage U 2 to 15,5 V [*]
Note: The limiting value for max. voltage 15,5V is a SAFETY LIMITATION
and can be adjusted due to long load cables.
See 5. c)DEVICEMENU – for device specific parameter setting
Current limiting
output current Imax Imax [*] depends on charger version (for details see data sheet)
Note: Imax is depending on the preset voltage
and limited via a dynamic temperature control
[*] Note: Should the preset power of the battery charger be higher than the nominal power of the device,
the DBL adjusts automatically the limiting values, if needed.
Example: If the voltage is in the threshold and the output voltage U is heightened further, so automatically the max.
current Imax is reduced and vice versa.
5. b) CHARGEMENU – for battery charge mode
Parameter Value Setting range / Information
Charging voltage U Utri to Umax (U = typ. 14,2 .. 14,8 V)
Note: In chapter 5. c) DEVICEMENU the max. charging voltage Umax
is fixed (standard value is 15,5V)
Trickle voltage Utri Umin to U (Utri = typ. 13,2 V)
Note: Limiting values for the trickle charge voltage are starting voltage and
adjusted charging voltage.
Starting voltage Umin 5V to Utri (Umin = typ. 5 .. 11,5 V)
Minimum voltage of the battery - this defines the voltage
limit which must be exceeded by the battery before starting to
charge.
Note: The starting voltage is a SAFETY FUNCTION which ensures that
for charging really an acceptable battery is connected.
Due to safety reasons in operation mode AUTOMODE no batteries are
accepted which have a lower voltage level than 11,0VDC. However should
a deep discharged car battery be charged, the operation mode has to be
set from AUTOMODE to CHARGEMODE.
Current limit Imax Imax depends on charger version (for details see data sheet)
Under Limit of Imax is dynamic and is the sum of the values Itri and Ire.
FC current Itri 1 to 20 Ampere (Itri = typ. 2,5 .. 10 A)
Current limit, below this value the DBL switches to trickle charge mode

Short circuit
current limit
LIMITING
PULSING
If an overload or a short circuit is detected (Uout drops below the voltage
limit Usrt) then the current is limited by the DBL charger:
If the voltage on the output drops below Usrt then the current is
limited to 0,5A.
If the voltage on the output drops below Usrt then the current is limited
to a fixed value of 0,5A for about 60 seconds. After this time interval the
current limit rises in order to test if the overload / short circuit is present
longer.
Altogether three pulses are given out from the DBL – should the overload /
short circuit be present any longer then no more trials are taken and
current is limited to max. 0,5A until a reset of the device.

7) Annex – CELLCHECK / SHORT CELL DETECT
To run this feature correctly, no load impedance may be connected in parallel to the charged battery.
Disconnect the battery from the vehicle before starting the cellcheck!
To detect defect batteries it is necessary to adjust the maximum amp-hour for the battery before the
charge operation starts. The adjusted ampere hours should not be less than the written ampere hours
on the battery because the unit stops charging before the battery is charged high enough. The best
way to detect defect batteries is to adjust the ampere hours 10 to 20% higher than the written ampere
hours on the battery. For example a battery with 50 ampere hours should be adjusted in the charger
unit with 60 ampere hours. In any case should the ampere hours in the charger unit be adjusted even
when the “CELLCHECK” is “OFF”, because the ampere hours menu limits the charge process and
avoids extreme over-charging. If the “CELLCHECK” is active, the charge process stops twice for 30
seconds automatically. During that stop the charger measures the battery voltage and the internal
algorithm separates good and bad batteries. In case of defect batteries stops the charging process
and in the display appears “SHORT CELL DETECT”.
