1 Supply and 1 Starter Battery



  • Charging programs No. 1, 2, 3 and 5 (gel, AGM, acid, start) adjustable to the battery type
  • Outstanding charging technology
  • The charging voltage is exempt from peaks, and it is controlled in such a way, that overcharging is excluded
  • For mixed operation with 1 supply and 1 starter battery, a separate starter charging program can be adjusted at the built-in charging current distributor
  • If required, the starter battery can also be charged with full charging current (short stop period of the vehicle)
  • Additional auxiliary charging port "S" for support charging and trickle charge of a further starter battery (max. 2 A)
  • All-automatic continuous operation for permanent readiness for use of the vehicle
  • Precise battery temperature compensation, temperature sensor(s) is (are) included in the standard delivery
  • Equalization function (the characteristic line IUIU can be activated manually for compensation charging of the cells)
  • Intelligent microprocessor control observing the simultaneous supply of consumers
  • Battery regeneration in case of extended stop periods twice a week
  • Compensation of the voltage loss on the charging cables ensuring exact observation of the charging voltage rates
  • Separation of the batteries in case of power failure, overheating, incorrect behaviour (safety relay for each charging port)
  • Adjustable silent run function (reduction at night)
  • Power pack function allows continued operation of the consumers and preservation of data, such as in case of battery replacement
  • The electronic system is protected against humidity
  • Variable fitting position
  • 4 Battery capacity rates can be adjusted (16 charging programs in total)
  • 2 inputs, each, for sensor (sense) lines and battery temperature sensors
  • Separate signalling port +86 for motor locking while the vehicle is connected to mains
  • Voltage compensation for external diode charging current distributor can be adjusted (+0.63 V)
  • The mains/charging capacity can be reduced in case of low capacity or restricted power supply, such as in case of weakly protected country current supply , generator operation etc. (power limit function)

Charging Programs

1 „Gel“: Charging Program for Gel Batteries, Characteristic Line IU1oU2oU3
Adapted to closed, gas-tight gel/dryfit batteries with determined electrolyte, which are generally requiring a higher charging voltage level and longer dwell times U1 to achieve short charging times with particularly high capacity storage and to avoid total discharge. Also recommended for EXIDE MAXXIMA a high-current battery in AGM filament technology.

2 „AGM“: Charging Program for AGM/Fleece Batteries, Characteristic Line IU1oU2oU3
Adapted to charging closed, gas-tight AGM (absorbed glass mat) batteries and batteries in lead-fleece technology requiring a particularly high level U1 with adapted dwell times for full charging and after that a moderate level U2 for trickle charge (round cell and plate technology).

3 "DIN 0510“: Charging Program for Lead, Acid/Lead-Acid Batteries, Characteristic Line IU1oU2oU3
General characteristic line DIN for charging and conservation to charge of open and closed lead storage batteries with removable cell plugs and possibility of acid level control and acid level correction (maintenance). Also suitable for recently developed, closed battery types (low-antimonous, with lead-silver alloy, calcium etc.) with low and very low water consumption.
Allows short charging times with high level U1, high charging factor and high acid mixing, even during stationary application (acid accumulation) of "wet" drive, lighting, solar, heavy duty and standard batteries.

5 „MOTOR“: Charging Program for Lead, Acid/Lead-Acid Batteries, Characteristic Line IU1oU2oU3 Characteristic line similar to dynamo/generator for mobile application (acid accumulation) with particularly low maintenance (battery gassing, water consumption). Charging and conservation of charge of starter batteries in intervention vehicles, according to a customary suggestion of the Standard Committee Fire Protection (FNFW). For conventional, standard starter batteries, starter batteries being "absolutely maintenance-free", "maintenance-free according to EN", "maintenance-free according to DIN", "maintenance-free", "lowmaintenance".
