Why YONHAN Battery Charger?

Versatile Compatibility

YONHAN’s battery charger isn’t just another device that claims to recharge batteries. Its versatility is unmatched. Whether you have a car, truck, SUV, ATV, motorcycle, or even a golf cart, this charger can handle it all. It’s designed to cater to 12-volt and 24-volt automotive, marine, and deep-cycle batteries, supporting types like AGM, GEL, EFB, SLA, Flooded (WET), and Calcium. With a much faster charging speed compared to standard 10A or 6A chargers, you’re not just buying a charger; you’re investing in reliable versatility.

Efficient Charging for Every Season

Ever scratched your head over battery issues during winter? YONHAN has that covered with its unique Winter and Summer modes. These modes intelligently adjust the charging rate based on the surrounding temperature, preventing unnecessary battery drain. Forget about the dread of holiday battery failures; the trickle charging feature ensures your battery stays in top condition, regardless of the season.

Advanced Battery Repair Mode

One of the standout features of the YONHAN charger is the built-in battery repair mode. Using high-frequency and low-frequency pulse technology, it can help resurrect and rejuvenate old or idle batteries. Keep in mind, though, that it’s not a miracle worker for completely dead batteries. However, if your battery fails to charge, this repair mode is your go-to solution for potentially extending its life, keeping your batteries fresh over long periods or holidays.

How YONHAN Enhances Battery Life

Trickle Charger for Maintenance

The trickle charging capability is a brilliant feature for anyone looking to maintain their vehicle battery over long periods. It prevents overcharging by switching to a trickle or float charging mode once your battery is fully charged. This means you can leave your battery over the winter months, return, and find it as fresh as when you left it.

Winter and Summer Modes Explained

The YONHAN charger automatically adapts to the seasons. In many regions, batteries are prone to drain quickly during colder months. The winter mode adjusts the charger to provide adequate power without overloading the battery. Similarly, during the hotter months, it switches to summer mode, ensuring the battery doesn’t overheat. This smart adaptation is perfect for those who face harsh seasons.

What You Need to Know

Remember, the YONHAN charger requires being plugged into a power outlet. It isn’t designed for totally dead batteries, specifically those below 0.3V, and it’s not compatible with lithium batteries. By keeping these points in mind, you’ll maximize your charger’s utility.
