DeWALT 4A Professional Charger/Maintainer. This 12V car battery charger features microprocessor technology, enabling it to charge most 12V batteries, including deep-cycle, gel, and AGM types. Its fully automatic microprocessor control adjusts the amperage rate for quick and safe charging and maintenance with a single button press. The high-frequency current pulse reconditions weak, sulfated, or deeply drained car batteries, while the microprocessor control adapts the current to match the battery type and condition. Over 20% more efficient and 50% lighter than conventional charging systems, this charger includes a winter mode for specialized battery charging in cold weather. The large, easy-to-read LCD display provides a full range of readouts, including voltage/amperage, charge capacity, and a "bad battery" indicator. Automatically switching to maintenance mode when the battery is charged, this charger ensures optimal battery performance and longevity.
