The CTEK MXS 5.0 is a fully automatic 8-step battery charger and maintainer for 12V lead-acid batteries, delivering up to 4.3A at 14.4, 14.7, or 15.8 volts. It charges batteries from 1.2 to 110Ah and maintains batteries up to 160Ah, so it suits everything from motorcycles to cars and light trucks. The 8-step process includes a unique reconditioning mode that helps recover deeply discharged and stratified batteries, plus built-in temperature compensation that adjusts charging voltage to the ambient conditions. It is spark-proof, reverse-polarity protected, and rated IP65 for splash and dust resistance, and it can stay connected long term without overcharging. CTEK backs it with a 5-year warranty.
