A multi-voltage charger, 6-volt (50-amps), 12-volt (50-amps), and 24-volt (25-amps), for lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion. Featuring ultra-flexible silicone cabling with protective nylon breaded shielding for maximum protection against abrasion. A dual-voltage power supply, 12-volt (50-amp) and 24-volt (25-amp), to maintain constant power delivery without unwanted ripple, noise, and transient spikes during ECU flashing, reprogramming, and diagnostic testing. An integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates to maximize battery life and enable fast charging. Detects batteries as low as 1-volt. All-new force mode that allows the ability to manually begin charging dead batteries down to zero volts. Automatically detects battery sulfation and acid stratification to restore lost battery performance for stronger engine starts and extended battery life. Battery repair modes for 6-volt, 12-volt, and 24-volt batteries.
