SAFETY

• Please read the manual carefully before use.
• This appliance can be used by children aged 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning the use of the appliance in a safe way and understand the hazards involved.
• Do not attempt to charge no-rechargeable batteries.
• Do not use the Standard or 14,7 charging program on a Li-Ion battery or the Li-ion charging battery on a lead-acid battery.
• After use, disconnect the mains power before disconnecting from the battery.
• Only use the charger in a well-vented area and on vented batteries.
• This charger has to be repaired by professionals.
• Do not do incorrect connections even though the charge output is protected against short-circuiting and wrong connections.
• The charger does not draw current from the battery when the main power is not connected.
• Do not install the charger in a highly flammable environment.
• Do not charge a damaged battery.
• During charging, battery gas which is very explosive can be developed. Take care not to have sparks, open flames, cigarettes, or similar in the vicinity of the battery, and make sure there is sufficient ventilation.
• The acid in the battery 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 WorkShopCharger 2.0 35A is based on modern switch-mode technology and galvanized divisions. This charger represents the latest technology within battery charging and will give the batteries optimum life. It is well suited to battery sizes up to approx. 600Ah and can maintenance charge the battery for an unlimited time. The charger can stand parallel charging up to 30A parallel consumption at the same time as it charges the batteries. The charging voltage is temperature compensated with an external sensor.

CHARGE PROCESS

See A on page 2. The figure shows the charging process in a graph with Voltage (V) and Current (I) over time (t) The charge status is shown by the LED display. See B on page

PRE ANALYSIS

The charger checks if the battery is correctly connected. The battery’s charge level (V) and total capacity (Ah) is measured to determine the correct settings for charging.

STANDARD CHARGING

The charger starts charging the battery with a constant current up to 14.4V (at 25°C). The charge voltage is then held constant at 14.4V and the charging current is reduced until it is below a defined level. The charge voltage then drops to 13.6V, before the long-term charging phase starts. During charging, the battery charge is shown by the number of LEDs illuminated. The blinking segment above these LEDs indicates active charging. Once full battery charge is reached, all 5 LED segments remain illuminated. If the measured battery voltage is below 2.0V, the charger will enter Error Mode, and the warning triangle above the battery indicator will start to flash.
14,7 BUTTON
Some batteries require a higher charging voltage than other batteries. If the 14.7V button is activated the maximum charge voltage will be 0.3V higher than the standard level. Always follow the battery manufacturer’s recommendation regarding charging voltage.
LI BUTTON
Pushing this button will activate the charging curve for Li-Ion batteries. The top charge voltage is 14,4V and float charge voltage is 13,5V. Temperature compensation is deactivated in this mode. In this mode, the charger will output power even if a battery is not connected.

POWER SUPPLY MODE

When the charger is turned off the button can be pressed until the LED shines one by one in a regular bottom to the top cycle. The charger will be in power supply mode regardless of the battery voltage after it has been turned on, so it can be used to change the battery of the car without loosing car settings/ data. In this mode, the charger supply 13.7V and max 35 Amp. If the output short circuit in this mode, the charger will go into error mode. You should press the power button to turn off the charger, correct the problem, then restart the charger (go to charger or power supply mode).
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-analysis. If the battery voltage drops below 12V within 2min, the charger will go into error mode and the red warning triangle will start to flash. The charging sequence will be stopped.
LONG-TERM CHARGING
After the battery is fully charged, the charger will deliver 13,6V with a maximum of 35A. This is indicated by all battery LEDs slowly pulsating.
TEMPERATURE BASED VOLTAGE COMPENSATION
The charger automatically adjusts the charging voltage to the correct level according to the ambient temperature. The default ambient temperature is 25°C. Voltage is reduced for higher ambient temperatures and increased for lower ambient temperatures. The correct amount is ±0.03V/°C. Max temperature compensate charging voltage is 15.3 V
USE
Read the user guide carefully. If there are any uncertainties, please contact DEFA or a qualified person.
For installation of the wall bracket, see E on page 4. Connect red clamp to (+) 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 shall always be taken into consideration. Connect the AC mains cable to the charger. Push the power button once. See figure 2, page 2. The charger will start up and initialize the pre-analyze process. To turn of the charger, push the power button again.
NOTE: To make sure the correct charging voltages are applied to the battery the charging cables must not be shortened or made longer. NOTE: See figure 6 on page 4. An optional hook can be installed. Do not add other weight to this hook than the charger with cables.

MAINTENANCE

Make sure that the connector on both charger and cables (C page 2) is free from moisture and dirt before using the charger. All batteries should be inspected monthly as a minimum to achieve the best possible safety. The charging process is in such a way that the batteries remain fully charged without further water consumption than normal evaporation. If future needs require a software update of the charger, it can be done through the micro-USB port at the end of the charger. See D page 2. Necessary information will be given along with the software.

WARRANTY

The guarantee applies to faults in production and materials for 2 years from the 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.
