## Questions & Answers

**Q: Hi , what is the charge capacity for this charger ? Will it charge a 100 AH battery ?**
A: The GENIUS1 can charge a 100 amp-hour battery, but it will be an extended charge time if the battery is completely dead. For example, the GENIUS1 would take roughly 76-hours to recharge a dead battery. For comparison, the GENIUS2 would be 37-hours, the GENIUS5 would be 15-hours and the GENIUS10 would be 7-hours.

**Q: Will it auto resume maintaining the battery after a power cut ?**
A: It should do as I understand anytime it is used it should start up from the last setting each time, so when I go to set up the charger next time it will automatically go to the 12V set up I used the first time.

**Q: Does anyone know if i have to disconnect the car battery leads first to use this charger? or can i literally pop the hood and connect it up?**
A: You do not have to disconnect the battery from the car.

**Q: Which model can you suggest for an audi tt, 3.2 l. the car is rarely used, but i want to keep the battery topped up**
A: The basic model I have found to be totally satisfactory….I use it on my Mazda 2…it was recommended by the AA guy who came to start my car.  Much better than my old charger.
