A modern microprocessor-controlled automatic charger is a versatile device designed for charging and maintaining 12V batteries.
Equipped with an intelligent control system and a 9-stage charging process, it ensures maximum efficiency and user safety.
It supports a wide range of battery types – from classic lead-acid to modern lithium iron phosphate (LiFePO4) batteries.
Thanks to the automatic temperature detection (winter/summer mode) and memory function for the last operating mode, the GEKO G80056 charger is exceptionally convenient and intuitive to use.
Charging modes are selected manually using the MODE button (except for winter and summer modes, which activate automatically).
Suitable for most 12V lead-acid batteries used in passenger cars, agricultural vehicles, and trucks.
Supports WET (flooded), MF (maintenance-free), and Ca/Ca (calcium) types.
Dedicated to 12V batteries used in vehicles equipped with Start-Stop systems, as well as AGM and GEL batteries.
Optimizes the charging process, protecting cells from overcharging and overheating.
Designed for all types of 12V lead-acid batteries used in motorcycles, scooters, and smaller vehicles.
Provides gentle and precise charging for lower-capacity batteries.
Specifically designed for charging lithium iron phosphate (LiFePO4) batteries at a charging voltage of 14.6V.
Ensures stable and safe charging of lithium cells.
NOTE: The LiFePO4 mode should be used exclusively for this battery type.
A special Pulse Repair mode designed for regenerating 12V lead-acid batteries (WET, GEL, AGM) that:
– have been unused for a long time,
– are deeply discharged, or
– show signs of sulfation.
This mode uses pulsed charging technology to improve capacity and extend battery life.
The repair mode does not have a memory function and must be activated manually.
The charger automatically detects ambient temperature and adjusts charging voltage:
Winter mode activates below 10°C, increasing voltage for more efficient charging in low temperatures.
Summer mode activates above 28°C, lowering voltage to prevent battery overcharging in high temperatures.
The charger uses an advanced nine-stage charging process, providing longer battery life and complete safety:
Battery detection
Desulfation (pulse)
Constant current charging (half power)
Constant current charging (full power)
Constant voltage charging
Regeneration / repair
Float charging (maintenance)
Capacity monitoring
Automatic charge completion
This ensures the battery is not only fully charged but also protected against overcharging, overheating, and cell damage.
After charging is complete, the charger automatically remembers the last used operating mode and restores it at the next startup.
This feature greatly enhances convenience – simply connect the device, and it will resume charging with previous settings.
(The repair mode is not covered by this memory function.)
After charging begins (about 25 seconds), the MODE button is locked, preventing accidental mode switching during operation.
To change the mode, one clamp or the power supply must be disconnected – this prevents user errors and battery damage.
