## Questions & Answers

**Q: Does the wall charger work on 220 volts?**
A: YES, your sigma 1 battery charger can be left connected to a 220V outlet. As long as the input voltage is between 100V and 240V, it will be able to recharge your car battery.

**Q: I need to charge my 1996 MR2 Japanese Model. I imported it from Japan. Will this work without removing the battery?**
A: Thank you for your interest in HULKMAN's products. The Sigma 1 can charge your battery without removing it. Please make sure to confirm the type of your battery before selecting the charging mode, the Sigma 1 is suitable for a wide range of 6V/12V lead-acid batteries and 12V lithium batteries, charging batteries up to 32Ah and maintaining all battery capacity.

**Q: what is the best us to uk adapter plug fit for this product,  for use in the uk.**
A: Since it’s a two prong there is no ground. so you can use a standard US to UK adapter

**Q: Can this charge a battery that is at 0%? I hooked it up and selected 12v but nothing seems to happen?**
A: I would try the 12v Repair mode instead of the normal 12v mode. I used thus mode for my motorcycle battery during the winter. This mode is also for older batteries. So this is probably the better mode if yo are at 0%. I'm not 100% on this but that is the route I would try. It takes 4 hours for the repair mode. Good luck.
