 CTEK’s MUS 4.3 battery charger is perfect for those with high demands and can solve a broad range of battery-related problems. The MUS 4.3 offers state of the art technology that was previously only found in CTEK’s professional products and features 8 patented steps to maximize battery life and performance. A few of the key features are a patented de-sulphation process which removes sulfate from the lead plates, a battery diagnosis that shows if a battery can receive and retain a charge, a special reconditioning function that restores stratified and deeply discharged batteries, unique maintenance charging, a mode for optimized charging during cold winter days and the charging of demanding AGM batteries (i.e. Optima). The unique LED display allows the user to follow the entire charging process. The MUS 4.3 is a non-sparking, short-circuit proof, reverse polarity protected unit designed for untroubled usage and has built in overcharging protection. With the optional Comfort Indicator Eyelet and Pigtail you can outfit all of your battery needs for multiple batteries. The MUS 4.3 is splash, dust and water-resistant so that the solution can be taken to the problem even if it rains or snows. Included with the MUS 4.3 is the charging unit, a Comfort Connect clamp, a Comfort Connect M6 eyelet and a storage bag. For complete operating instructions please read the enclosed manual in the box. All CTEK products are delivered with a 5 year limited warranty from the original purchase date. If you store your FIAT through the bad months or only use it for the weekends a good trickle charger/battery charger is a good idea. Includes a quick connect cable you can leave attached to the vehicle. (Same Charger that ships with the Alfa Romeo 4C)
