Main highlights

Multi Safety Protection & ETL Certification: The charger provides multiple protections to ensure safe use, including spark-proof, reverse polarity, overcharge/discharge, overvoltage, overcurrent, overload, overheating, current backflow, short circuit, etc. The upgraded cooling system improves performance. ETL certification makes it safe to use
HD LCD Screen and 8-Stage Intelligent Charging: With true 8-stage smart charging (desulfurization, soft start, bulk charge, absorption, analysis, repair, float, and pulse maintenance), it optimizes battery life and repairs batteries without overcharging or damaging them. The HD LCD screen allows you to view the charging stage and parameters at any time rather than leaving you guessing, keeping you informed of the charging status
Fully Automatic Charging for Convenience and Safety: This 12 volt battery charger automatically detects battery status and starts charging automatically within 30 seconds if you forget to press Start. After a full charge, it enters pulse repair mode, turns off the screen to save energy, and maintains a safe voltage for long-term storage. If voltage drops, it restores full power. The smart battery charger also remembers your last settings, ensuring seamless operation even after a power outage
Fix “PLEASE PUT THE CLAMPS ON” Error & Charge Batteries Below 1V: If the charger is powered on and the clamps are correctly connected to the battery terminals, but the screen still shows “PLEASE PUT THE CLAMPS ON,” this means the battery voltage is too low (below 1V) and cannot be detected. Press the “Recondition” button to activate the manual repair mode. If the battery responds, the charger will automatically begin charging after 30 seconds. Note: This feature does not work on completely dead batteries
Engine Start & Winter Mode: Engine start delivers 100A current helps activating your car battery to start your vehicle in 100 seconds. Winter Mode, +0.2v on the basis of the original charging voltage, better boosts your battery activity and charges more thoroughly in low-temperature situations
Efficient, Energy-Saving, and Fast Charging: The TowerTop 12v battery charger offers 4 adjustable current settings (2A/10A/25A/AUTO) to meet your diverse needs. With a max charging current of 25A, you can fully charge a 100Ah battery in under 3.5 hours. Achieving an 85% charging efficiency (industry average 75%), this battery chargers is more efficient, increasing charging speed by 1640% compared to 2A car battery charger. Not only is it energy-efficient, but it also saves you a lot of wait time
Battery Repair: Independent desulfurization and repair buttons allow you to manually desulfurize and repair your battery to restore lost battery performance, helping to revive old/idle batteries and extend battery life. If your battery cannot be charged, you can try the "repair" mode to fix it. Note: It cannot repair completely drained batteries
All-in-One Compatible Design: Designed for 12V sealed lead-acid batteries in cars, boats, RVs, power sports, and deep-cycle batteries, including 12V STD, AGM, GEL, Wet, MF, EFB, calcium and deep-cycle batteries
