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.
