SAFETY
- Please read the manual carefully before use.
- Inexperienced users, children aged 8 and above and persons with reduced physical or mental capabilities must only use this product under supervision or after having read or been given instructions on safe use.
- Do not attempt to charge non-rechargeable batteries.
- Only charge lithium batteries with an integrated Battery Management System (BMS).
- After use, disconnect the mains power before disconnecting from the battery.
- Only use the charger in well-ventilated area and on vented batteries.
- This charger must only be repaired by professionals.
- Never intentionally connect the charger incorrectly, even though it is protected against short-circuiting and reverse polarity.
- The charger does not draw current from the battery when the mains power is not connected.
- Do not use the charger in a highly flammable environment.
- Do not charge a damaged battery.
- During charging, batteries may release highly explosive gasses. Take care not to have sparks, open flames, cigarettes or similar in the vicinity of the battery and always ensure sufficient ventilation.
- Battery acid is corrosive and harmful. It damages clothes, metal and varnish. In case of spillage and contact with skin, wash and rinse thoroughly with water and consult a doctor.
- Lead and other chemicals that are used in batteries are toxic. Wash skin and hands thoroughly after working with batteries.
ABOUT THE CHARGER
DEFA ShowroomCharger is based on modern switch-mode technology. This charger
represent the latest technology within battery charging and will give the
batteries optimal performance and durability. It is well suited to charge
lead/acid, AGM, EFB, GEL and lithium-ion batteries up to approx. 600 Ah for a
unlimited time.
INSTALLATION
The charger can either be installed by fixing the bracket directly to a wall
or be hung on a wall bracket. See C and D page 3 for drill patterns.
See figure B, page 2

USE
Read the user guide carefully. Please contact DEFA or a qualified person if
you are unsure about how to safely use the charger.
Connect red clamp to positive battery terminal (+) and black clamp to (-) or
the connection point recommended by the vehicle manufacturer. The charger is
intended for use with lead/acid, AGM, EFB, GEL and Lithium batteries. The
battery manufacturer’s recommendations for charging voltages shall always be
taken into consideration.
If the temperature sensor is connected, the charge voltage will be temperature
compensated. Lithium charging programs do not include this function. Connect
the AC mains cable to the charger. Push the power button. The charger will
start. To turn off the charger, push the power button again. If the power is
turned off or there is a power outage during an ongoing charge cycle or power
supply mode, the charger will continue the current operation when power is
restored.
NOTE: To make sure the correct charging voltages are applied, the
charging cables must not be shortened or made longer.
MENU/OPERATION
A scroll wheel and a back button is used to operate the charger. The scroll
wheel can be turned in both directions and can also be pushed down. Turning
the scroll wheel will switch between the different options available, and
pushing the scroll wheel will make a selection. The back button is used to go
back to the previous screen in the menu.

CHARGE PROCESS
See A on page 2. The figure shows the charge process in a graph with Voltage
(V) and Current (I) over time (t). The charge status is shown in the LCD
display.
PRE-CHARGING ANALYSIS
The charger checks if the battery is correctly connected. The battery’s charge
level (V) is measured.
CHARGING
The charger starts charging the battery with constant current up to the
defined level in the selected charge mode. The charge voltage is then held
constant at this level and the charging current is reduced until it is below a
defined level. The charge voltage then drops to to the defined level in the
selected charge mode, before the long-term charging phase starts. If the
measured battery voltage is below 2.0V in 12V or 4V in 24 mode mode, the
charger will enter error mode, and a warning is shown in the dispaly.
POST ANALYSIS
The charger analyses the battery again after the charging phase. Post analysis
can detect batteries with a short circuit in individual cells. This cannot be
detected in the pre-charging analysis. If the battery voltage drops below 12V
or 24V within 2min, the charger will go into error mode and a warning will be
shown in the display. The charging sequence will be stopped.
LONG-TERM CHARGING
After the battery is fully charged, the charger can be left connected to the
battery for an unlimited time without damaging the battery. The charging
process is designed in such way that the batteries are kept fully charged
without causing excessive water consumption.
EXPERT MODE
This charger has a feature called “Expert mode”. In this mode a Custom battery
type option will be available in the battery type selection. Here the top
charge voltage and the float charge voltage can be set by the user. To enter
Expert mode a PIN have to be entered, The PIN is 3332.
MAINTENANCE
Make sure that the connectors on both the charger and the cables are free from
moisture and dirt before using the charger. All batteries should be inspected
monthly as a minimum to ensure maximum safety.
The filter in the air inlet on the bottom side of the charger should be
inspected and cleaned on a regular basis. See E, page 3. The charging cables
should be inspected for damage on a regular basis.. If the cables get damaged
they can be replaced by removing the cover below the charge cable. The screw
terminals for the charging cable can be found under this cover.
If future needs require a software update of the charger, it can be done
through the micro-USB port. See B page 2, number 5. Necessary information will
be given along with the software.
WARRANTY
The guarantee applies to faults in production and materials for 2 years from
date of purchase. The customer must deliver the product back to the place of
purchase together with the receipt. The guarantee shall cease to apply if the
charger is handled negligently, opened or repaired by someone other than DEFA
or an authorized representative of DEFA. DEFA has no other guarantee than this
and will not be responsible for other costs than those referred to, i.e. no
possible additional costs. Neither is DEFA bound by any other guarantee.
