5.0A 12V. For 20Ah to 160Ah lead-acid (AGM; GEL; EFB; MF; CaCa) batteries. This CT5 TIME TO GO battery charger and trickle charger / maintainer is a world first since it and answers the question: ''When will my battery be fully charged?'' After connecting it calculates the remaining charging time in hours; presenting it to you in a countdown style. When it is safe for the battery to start; before the battery is fully charged; it will let you know. A time saver. The CT5 TIME TO GO uses advanced technology with three charging and maintenance programs: Normal (lead acid batteries); AGM (Absorbed Glass Matt) and Recond (an automatic desulphation program to recondition a sulphated battery; to it more efficient again). During winter time; or other long storage times the CT5 TIME TO GO can be left connected to the battery for as long as you wish. It will never allow under or overcharging of the battery. - 12 V / 5A / 14.4/14.7/15.8V - 20-160Ah compatible - Compatible with lead-acid (AGM; GEL; EFB; MF; CaCa) batteries - ''Try'' indicator shows when it is safe to make one attempt to start - Test and restore battery capacity - Normal program for medium lead-acid batteries - AGM program for medium lead-acid AGM batteries - Safe spark free operation - Reverse polarity protected - Short circuit proof - Splash and dust proof (IP65)
