KONNWEI RC-10 12V/24V Smart Battery Charger

KONNWEI RC-10 is a compact, fully automatic smart battery charger and pulse repair tool designed for 12V and 24V vehicle batteries. It is suitable for cars, motorcycles, SUVs, trucks, boats, lawn mowers, garden equipment, engineering vehicles and other battery-powered vehicles or machines.

The charger automatically manages the charging process and uses a 7-stage charging algorithm to charge the battery safely, efficiently and with better long-term care. In 12V mode, the RC-10 can deliver up to 10A charging current, while in 24V mode it can deliver up to 5A, making it faster than many standard 5A or 8A battery chargers.

🔄 7-Stage Charging Process

1. Battery desulfation – helps reduce the effect of sulfate crystals on the battery plates.
2. Soft start charging – starts charging gently with a lower current.
3. Bulk charging – quickly restores the main battery capacity.
4. Absorption charging – stabilizes the voltage and completes the charging process.
5. Battery test – checks the condition of the battery.
6. Recondition charging – helps improve battery condition.
7. Float & maintenance charging – keeps the battery charged and helps prevent overcharging.

🛠️ Pulse Repair Function

The RC-10 includes a dedicated pulse repair mode using pulse voltage and current. This function is intended to help reduce battery aging symptoms, detect and address sulfation and acid stratification, and partially restore lost battery performance.

Important: the repair function cannot restore mechanically damaged, short-circuited or completely worn-out batteries. When using repair mode, it is recommended to disconnect the battery from the vehicle electronics.

🖥️ Display Information

The intelligent digital screen allows easy monitoring of the charging process. It may show:

• Battery voltage
• Charging current
• Battery charge percentage
• Ambient temperature
• Selected charging mode
• Winter / summer temperature compensation indication
• Full charge, fault or repair status
