## Questions & Answers

**Q: I used this in my mercedes c class 2013 and it did not work with the cigarette lighter attachment . Can you advise why?**
A: Suppose you checked the lighter socket is live with ignition off?

**Q: I have plugged my traffic light adapter into a live cigarette socket, the battery is fully charged but the indicator only shows a red light**
A: Hello. In my case the stop/start function stopped working, I suspected it was a battery issue but did not have any problems starting. It was in the middle of the first lockdown and the car had been in the garage for long periods of time, I thought the battery just needed a boost. I bought a smart charger and the traffic light adaptor. The traffic light was red, so I put the battery on charge it took 7 hours until it indicated full charge. A month later I was back in the same situation, the battery was 4 years old so I replaced it. I think the battery needs to be more than 80% charged for the stop/start to work. I noticed in hindsight that well known car accessory stores will perform an in depth check on the health of the battery, I should have gone down this route rather than buying the charger etc. The car hadn't moved since Friday, I tried the traffic light this morning and it was green. Hope this helps

**Q: Will this work in a din socket?  is it just a case of taking that red connector off?  looking to use on my motorbike.**
A: Hi yes it is

**Q: Can thsi be used with 12 volt lithium lifepo4 car starter batteries or is it only for lead-acid batteries?**
A: This is an electronic device designed to measure a car battery voltage via  car's cigarette lighter. The type of battery should be irrelevant.
