Stay in control Life is wonderful—and it's even better when you're in control of your own time. When you dream of the freedom and adventures your vehicle can offer, battery charging is hardly the first thing that comes to mind. But realistically, battery charging is the easiest and most time-saving vehicle maintenance you can do. With CTEK's unique TIME TO GO feature, you stay in control and can plan your day as the remaining charging time can be predicted with great precision. MAXIMIZE BATTERY PERFORMANCE CT5 TIME TO GO is based on Swedish engineering and offers maximized life and performance for all 12 V vehicle batteries. You can ensure that your battery is always in good condition, even in winter, and you can even recondition a discharged battery if you accidentally leave it unattended. CT5 TIME TO GO is easy to use and fully automatic – the technology monitors the battery and takes the necessary measures to take care of your particular battery. FULL CONTROL OVER CHARGING TIME CT5 TIME TO GO is the only charger on the market that can notify you when the battery is ready for use. A series of LED lights indicate the different charging phases and how long it takes before the battery is sufficiently charged. There are also indicators that let you know when it's safe to attempt a start (TRY) and when the battery is sufficiently charged to go (GO). This information is provided as a practical guide only – it is perfectly safe to leave the CT5 TIME TO GO charger connected 24 hours a day, all year round. CT5 TIME TO GO is the first charger in the world to notify you exactly when your battery is fully charged. A row of seven LED lights indicates the different charging phases and how much time is left (in hours) before the battery is charged. Countdown to fully charged battery, in hours · 8h More than eight hours until charging is complete · 4h Approximately four hours until charging is complete · 2h Approximately two hours until charging is complete · 1h About an hour until charging is complete TRY - A lit TRY indicator means that it is possible to perform a start attempt. GO - 8 h | 4 h | 2 h 1 h > GO. - A single lit LED tells you exactly how much time is left until the battery is fully charged. When the GO LED lights up, the battery is 80% charged and completely ready for use. CARE - Leave the battery connected for safe long-term storage and your vehicle will always have a fully charged battery when you want to use it. NORMAL - Charging program for medium-sized lead-acid batteries. AGM - Charging program for medium-sized AGM batteries. RECOND - Charging program for the reconditioning of deeply discharged batteries.
