TowerTop 2/15/25 Amp Car Battery Charger, 6V/12V Fully Automatic Smart Battery Maintainer with Engine Start, Auto Desulfator, Battery Repair, Winter Mode, for All Lead-Acid and LiFePO4 Batteries

Description

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’ll 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 overlook to press the start button, it is going to 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 protected 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 calcium and lithium (LiFeP04) batteries, as well as 6V and 12V lead-acid batteries, including STD, AGM, GEL, Wet, MF, EFB, and deep-cycle batteries. The charger also has a memory function to take into account that the last settings, ensuring uninterrupted charging even all through 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, flow, and pulse maintenance), it optimizes battery life and repairs batteries without overcharging or damaging them. The HD LCD screen permits 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 help you 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’ll 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 make sure protected 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 protected to use.
