The car battery charger is an 11-step automotive battery charger suitable for charging and maintaining 6V or 12V lead-acid batteries. It supports batteries with liquid electrolyte, maintenance-free lead-acid batteries, gel electrolyte, or absorbed glass mat (AGM) batteries. Select the desired charging voltage (6V or 12V), and the microprocessor-controlled charger will handle everything automatically until the charging cycle is complete and for maintaining fully charged batteries. The German-language display is easy to understand and comfortable to use. Thanks to the testing function, battery charge levels can be determined before charging, and the integrated memory function continues the charging process even after power interruptions without having to start over. Six charging programs are available. The fully automatic battery charging occurs in 11 charging steps. Modern safety technology with reverse polarity protection, overheating protection, overload protection, and short-circuit protection safeguards you and the device from incorrect operation. Two cables with quick connectors and comfort plugs (permanent charging cable with ring terminals for fixed installation and charging cable with clamps) are included with the splash-proof and dust-tight device (protection class IP65).
