## Questions & Answers

**Q: Will this restore to previous setting and continue maintenance after a power cut? My current one had to be reset each time**
A: It returns to the settings you had before

**Q: Can you use this to jump start a car if the battery is dead with no access to a power outlet**
A: No. The GENIUS5 is a battery charger that recharges a battery only when plugged into an A/C outlet. It is not a jump starter. See NOCO Boost UltraSafe Lithium Jump Starters.

**Q: When using this charger do you need to disconnect your car battery?**
A: For the normal charge mode it should be safe to charge with battery connected but if using the repair mode I think it would be safer to disconnect as it puts out more voltage (over 15v) and could damage any sensitive electronics, like the ECU.

**Q: Ive charged my battery but instead of a solid green light after i have a pulsing green light lasting 2-3 secs. Is it fully charged?**
A: Yes, it is fully charged but leave the device connected unless you need to use the vehicle. Flashing green means the Noco is reconditioning the battery for longevity and easier future charging. After I charged my (knackered) battery, I had flashing green for at least another 24 hours. Leave it, if you can. It will go solid green eventually.
