## Questions & Answers

**Q: Does this work with AGM?**
A: It will work with any vehicle.

**Q: Do you need a switch inline to prevent the voltmeter from being constantly on when vehicle not in use?**
A: Yes, need one, usually connected to the car battery, but it is connected indirectly.

**Q: will this go to 16.5 volts ?

Thank You**
A: No it will not. This voltmeter monitors automotive battery voltage and anytime voltage is above 14.7 volts the indicator will blink and a buzzer will sound warning of voltage too high.

**Q: what is the mAmp drain ?**
A: The current drain is not the problem.  The problem is that they are utter junk.  I had 3 sets of these all fail within a short time, in the same manner (died to show a constant 5.5v in a 12v system) - the original set, and two warranty replacement sets.  I finally gave up on them, even as warranty replacements.  Bought replacements from PowerWerx, and they've been going fine for over a year, with no discernible issues.  Slightly more expensive, but you get what you pay for.
