Tested safety and robust design: Your safety is our highest priority. Equipped with 8 intelligent protection mechanisms (reverse polarity, short circuit, overvoltage, overheating protection at 65°C and much more). and a housing made of flame retardant ABS material (CE certified). Charge your valuable batteries with the peace of mind that your vehicle and workshop are reliably protected. The extra long cables (150 cm + 90 cm) offer maximum flexibility.
One charger for everything: 12 V/24 V and all battery types: Forget the mess of different chargers. This universal genius automatically detects 12V and 24V systems and is designed for a huge range of 2Ah to 300Ah. Whether lead-acid (AGM, GEL, EFB, calcium) or modern lithium iron phosphate batteries (LiFePO4) in your car, boat, tractor or forklift – all you need is this one, highly compatible workshop charger for your entire fleet.
Intelligent technology for any weather: maximum performance, whether in ice cold or summer heat. The integrated temperature sensor automatically adjusts the charging voltage to the ambient temperature (-15°C to 45°C), thus preventing overcharging in summer and undercharging in winter. The practical memory function saves your last selected mode, while the large, clear colour display clearly shows you all important data such as voltage, current and charging status at all times.
Full control: 1-20 A current manually selectable: no more universal chargers that charge too slowly or aggressively. Our charger gives you full control: manually select the perfect charging current from 1A to 20A. Ideal for gentle trickle charging of the motorcycle battery (2A) or the powerful fast charging for trucks and motorhomes (20A). The result is maximum charging efficiency and a significantly longer life of your battery.
9-stage repair charging and 0.3 V reactivation: your battery seems dead? Do not throw away! Our charger launches an advanced 9-step rescue process that fights sulfation and restores cell chemistry. Thanks to the ability to reactivate even deeply discharged batteries with only 0.3V residual voltage, it brings batteries to life where others give up. This saves you the cost of an expensive new purchase and protect the environment.

[7 Charging Protection, Never Stranded Again] The charging cable contains heat-resistant and oxidation-resistant copper wire, which is not easy to break. It has protection circuits for overcharge/over-voltage/over-current/short circuit and has functions such as polarity protection, short circuit protection, connection error battery protection, overheating protection, overvoltage protection, undervoltage protection, etc.
With the latest technology in battery chargers. Switching mains chargers convert 220-240V AC with electronic components into 12V DC, unlike conventional battery chargers that rely on heavy transformers. This allows the charger to be lightweight and compact without sacrificing performance.
The battery charger has an 7-step fully automatic charging cycle. The cycle is repeated infinitely. If the terminal voltage drops below a lower limit, the charger automatically goes back to the beginning of the charging curve. The 7 stages are:Desulphation ; Soft Start; Bulk; Absorption; Battery Test; Recondition and Float.
Extend battery life: compatible with all 12V lead-acid, flued, AGM and gel cell batteries. Complete 7-stage charging program (initialization, bulk charge, float mode) allows optimization of battery performance without overcharging
Built-in advanced battery repair mode to restore old/idle batteries and extend battery life. The high frequency and low frequency pulse technology has good repair and activation effects. Note: It cannot activate a dead battery or repair a damaged battery. Lithium batteries are not allowed
