12V/24V 20A Car Battery Charger Intelligent Pulse Repair Smart Automatic for Car

Product Description：

20A High-Speed Charging Function: Suitable for 12V and 24V batteries. Specifically designed to enhance efficiency. It can provide up to 20A of maximum current for 12V batteries and 10A of maximum current for 24V batteries. The charging speed is twice as fast as the standard 10A charger. It is highly suitable for quickly charging heavy batteries (4-400 ampere-hours) in vehicles such as cars, trucks, SUVs, marine vessels, and campers. The intelligent detection function automatically identifies the 12V or 24V system during connection. 

200-second Boost Mode: Prevent getting stranded due to depleted battery power. Select the "Boost" mode and enjoy a 200-second rapid and targeted charging process. The screen will display a clear countdown timer. When the timer ends and the screen shows "ON", your battery has acquired sufficient surface charge, which is beneficial for starting the vehicle. Note: This mode is applicable to 12V lead-acid batteries. 

️Advanced pulse repair and maintenance: Do not immediately replace the battery. The dedicated repair mode employs high/low frequency pulse technology to eliminate sulfation and restore the performance loss of old, idle or layered lead-acid batteries. The charger also has winter/summer modes, which can automatically adjust the voltage according to the ambient temperature to prevent overcharging in cold environments or overdischarging in hot environments. 

Intelligent Cooling and Multiple Protection: A built-in cooling fan is included, which can effectively dissipate heat during high-current charging to ensure stable performance. The intelligent microprocessor conducts round-the-clock safety monitoring, including protection against reverse polarity, short circuit, overcurrent, and overheating. The LCD display will continuously display voltage, current, and temperature data for real-time monitoring. 

️Exclusive three chemical substance support (lithium-ion / lithium iron phosphate / lead-acid): Unlike the standard charger that is only applicable to lead-acid batteries, this multi-functional device has dedicated modes specifically designed for 12.6V lithium-ion (teralloy/NMC) and 14.6V lithium iron phosphate batteries, as well as AGM, GEL, SLA and wet batteries. One charger is suitable for all battery types - whether it's a custom lithium battery pack or a standard automotive battery. 

Note:

Before connecting the battery or the battery that needs charging, please first select the mode on the charger and keep it in the "off" state (as in normal circumstances). Before selecting the mode, the positive and negative electrodes must be fixed on the battery for it to take effect. Additionally, this product is only a charger. It will not work if not connected to an AC power source. Do NOT use Repair Mode or Boost Mode for lithium batteries.
