About this item

  • 24V/12V BATTERY CHARGER : Why buy multiple chargers when one does it all? The KONNWEI smart battery charger automatically detects 12V and 24V systems for fast and efficient charging. As a versatile auto battery charger, it is fully compatible with all Lead-Acid, AGM, EFB, and GEL types, and LiFePO4.
  • ADVANCED BATTERY DESULFATOR FUNCTION: Can it save an old, underperforming battery? Yes! Built with high-frequency pulse repair technology, this smart charger functions as a powerful battery desulfator. It automatically detects battery sulfation and acid stratification, helping to restore lost battery performance, strengthen engine starts, and significantly extend battery life. NOTE:The damaged battery cannot be repaired.
  • BATTERY TRICKLE CHARGER & MAINTAINER : Is it safe to leave your battery connected during the off-season? Absolutely. Once the battery is fully charged, simply switch to "Motorcycle" mode, and the charger will automatically enter a trickle charging mode. This keeps your battery at full capacity for months at a time without any risk of overcharging—the perfect, worry-free solution for the seasonal storage of motorcycles, ATVs, and other power sports vehicles.
  • TEMPERATURE COMPENSATION & Muti-PROTECTIONS: Worried about your car’s electronics? We’ve got you covered . It is engineered with a comprehensive safety shield that includes reverse polarity protection, short circuit prevention, and overcharge protection. Additionally, the built-in temperature compensation automatically adjusts the charge voltage based on the ambient climate—preventing undercharging in cold winters and overcharging in hot summers.
  • WIDE APPLICATIONS : What vehicles can I use this on? It is the ideal car battery charger and motorcycle battery charger, while also delivering reliable power for Boats, ATVs, RVs, and Lawnmowers. The compact size makes it easy to store in any garage or trunk, and the 2.4" LCD screen provides clear, real-time feedback on charging status, voltage, and battery health at a glance.
