Never Face a Dead Battery Again
This intelligent maintenance charger keeps your vehicle battery at peak performance with continuous voltage monitoring and automatic adjustment. Advanced microprocessor technology detects exactly when your battery reaches full capacity and stops charging automatically, eliminating the risk of overcharge damage. The pulse repair function actively reverses sulfation buildup and restores internal resistance in weakened batteries, giving you professional-grade recovery capabilities at home. With temperature-adaptive charging that adjusts current flow based on ambient conditions, you get reliable year-round protection whether stored in freezing garages or summer heat. The 61-inch total cable length with pure copper construction reaches batteries in tight engine compartments while maintaining stable, heat-free power delivery you can trust.

Why You Need This
- Saves Money on Replacements: Pulse repair technology breaks down sulfate crystals and reactivates batteries other chargers abandon, extending lifespan by up to three years.
- Works with Modern Battery Types: Dedicated AGM, GEL, and start-stop modes deliver the precise voltage curves these sensitive batteries require for optimal longevity.
- Eight-Layer Protection System: Reverse polarity, short circuit, overvoltage, overcurrent, overheating, and low voltage safeguards protect your battery and vehicle electronics.
- Set It and Forget It: Automatic shutoff at full charge lets you connect overnight or for months of storage without worry about overcharging.
- Universal Vehicle Compatibility: Handles all 12V lead-acid batteries from 4Ah to 100Ah—cars, motorcycles, SUVs, boats, and engineering vehicles with one device.
- Real-Time Monitoring: LCD display shows voltage progress, charging status, and mode selection so you always know what's happening.

What Our Customers Say
Discover what makes THOMLER special.
Love that it automatically stops charging—no more babysitting overnight.
Works great with my truck's AGM battery and the cable reaches perfectly.
Been using this on my classic car during winter storage for two months now. The LCD display makes it easy to see what's happening, and I appreciate the temperature-adaptive charging since my garage gets pretty cold.
Picked one up for my boat and my daily driver SUV. The microprocessor adjustment feature gives me confidence I'm not damaging either battery, and the eight-layer protection system is exactly what I was looking for in a quality charger.
The pure copper construction on the cables feels premium, and knowing it handles everything from my sedan to my motorcycle makes this a solid investment. The automatic shutoff means I can leave it connected without overthinking it.
