## Features

- Efficient, Energy-Saving, and Fast Charging: The TowerTop Trickle Charger offers 4 adjustable current settings (2A/15A/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 charger is more efficient, increasing charging speed by 1640% compared to 2Amp chargers. Not only is it energy-saving, but it also saves you a significant amount of waiting time
- Fully Automatic Charging: The charger automatically recognizes charging. If you forget to press the start button, it will start charging after 30 seconds. Once fully charged, it switches to pulse repair mode and turns off the screen to save energy, maintaining the battery at a safe voltage level for long-term storage. When the battery voltage drops too low, the charger automatically restores full output power and switches back to pulse maintenance mode after reaching full charge
- All-in-One Compatible Design: Designed for 6V and 12V sealed lead-acid batteries in cars, boats, RVs, power sports, and deep-cycle batteries, including 12V deep-cycle and lithium (LiFeP04) batteries, as well as 6V and 12V lead-acid batteries, including STD, AGM, GEL, Wet, MF, EFB, and calcium batteries. The charger also has a memory function to remember the last settings, ensuring uninterrupted charging even during long-term use without worrying about power outages
- 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, keeping you informed of the charging status.
- 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.
- 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.
- 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.
