It charges batteries from 1.2 to 110Ah and maintains batteries up to 160Ah, and it adds a dedicated cold-weather program that charges reliably in temperatures down to -30C, which is -22F, where a standard charger can struggle. It ships with specially adapted AC and DC cables that stay flexible in the cold and a tough, robust casing, and it uses CTEK's patented float and pulse maintenance to keep a battery healthy over a long winter without overcharging. It supports WET, MF, Ca\/Ca, AGM, EFB, and GEL batteries, includes smaller-battery, normal, AGM, and reconditioning programs, and is rated IP65. CTEK backs it with a 5-year warranty.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: fully automatic 8-step charger and maintainer, cold-weather\u003c\/li\u003e\n\u003cli\u003eOutput: 4.3A, 12V\u003c\/li\u003e\n\u003cli\u003eCharges 1.2-110Ah; maintains up to 160Ah\u003c\/li\u003e\n\u003cli\u003eCold-weather program charges down to -30C (-22F)\u003c\/li\u003e\n\u003cli\u003eSpecially adapted cold-flexible AC and DC cables\u003c\/li\u003e\n\u003cli\u003eBattery types: WET, MF, Ca\/Ca, AGM, EFB, GEL\u003c\/li\u003e\n\u003cli\u003ePatented float\/pulse maintenance; smaller-battery, normal, AGM, Recond programs\u003c\/li\u003e\n\u003cli\u003eIP65; warranty 5 years\u003c\/li\u003e\n\u003cli\u003ePart number: CTEK56-958\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat makes the MXS 5.0 Polar different?\u003c\/h5\u003e\u003cp\u003eIt is built for extreme cold, with a dedicated cold-weather program that charges down to -30C (-22F) and specially adapted cables that stay flexible in freezing temperatures.\u003c\/p\u003e\u003ch5\u003eWhat batteries does it charge?\u003c\/h5\u003e\u003cp\u003e12V batteries from 1.2 to 110Ah, and it maintains batteries up to 160Ah, across WET, MF, Ca\/Ca, AGM, EFB, and GEL types.\u003c\/p\u003e\u003ch5\u003eIs it safe to leave connected all winter?\u003c\/h5\u003e\u003cp\u003eYes.
