2. Noco Genius 5EU
This fully automatic battery charger is suitable for 6-volt and 12-volt lead-acid batteries as well as lithium-ion batteries in cars, motorcycles, RVs, boats, and scooters. It can even charge nearly empty batteries with only 1 volt of remaining voltage. With the help of the integrated temperature sensor, the device measures the ambient temperature and adjusts the charging power accordingly. This prevents overcharging in heat and undercharging in cold conditions. In addition to the various charging modes, there is also a 12V repair mode, which is an advanced recovery mode for repairing and storing old, unused, damaged, layered, or sulfated batteries. In forced mode, even completely empty batteries with no remaining voltage can be manually recharged. The package includes the battery charger with interchangeable connection, a user manual, two cutting screws, a mounting bracket with Velcro, and clamps with integrated eyelets.

5. Dino Automatikladegerät
Select the desired charging voltage and the microprocessor-controlled charger takes care of everything fully automatically until the charging cycle is complete and the batteries are fully charged. The German-language display is easy to understand and convenient to operate. The memory function continues the charging process even after power interruptions without having to start from the beginning. There are four charging programmes to choose from. Fully automatic battery charging takes place in five charging steps. The microprocessor in the charger has a memory function. If the 230V supply is interrupted during the charging process, the device saves the previously selected charging programme. When the mains power supply is restored, the device restarts automatically and continues charging in the last selected programme.
Programmes:
Programme 1: 6 V (7.2V/1A) - Suitable for 6 V batteries with a capacity between 1.2 and 30 Ah in normal condition. Charging programme for WET, MF, EFB batteries and most GEL batteries.
Programme 2: 6 V (7.4V/1A) - Suitable for 6 V batteries with a capacity between 1.2 and 30 Ah in cold conditions. This charging programme is also designed for many AGM and some EFB batteries.
Programme 3: 12 V (14.4V/1A) - Suitable for 12 V batteries with a capacity between 1.2 and 30 Ah in normal conditions. Charging programme for WET, MF, EFB batteries and most GEL batteries.
Programme 4: 12 V (14.7V/1A) - Suitable for 12 V batteries with a capacity between 1.2 and 30 Ah in cold condition. This charging programme is also designed for many AGM and some EFB batteries.
Charging steps:
Step 1: Initialisation - Checks the condition of the battery to determine the charging process. If the battery is deeply discharged, pulse charging is initiated to refresh the battery.
Step 2: Pulse charging - Achieves the recovery process of deeply discharged or sulphated batteries through weak pulsating current.
