## Questions & Answers

**Q: can it be used for trojan industrial batteries?**
A: It can be used on any battery as it only checks the specific gravity of the acid.  Works great by the way...

**Q: Could this be used to add distilled water too, say drawing the water out of a cup? Looking for multifunction instead of buying tester and filler.**
A: Do NOT buy because MIGHTY MAX is selling it, they are a rip off company who only takes other peoples items and rebrands them to resell, they have NO CUSTOMER SUPPORT, the BATTERIES THEY SELL ARE JUNK TOO.

**Q: How do I read it no marks on large tube ?**
A: Read at water level on the inner float.

**Q: What exactly is the difference between the car, boat/marine, and golf cart models?**
A: Car. Boat.marine all have starting capacity of 100 amps a golf cart use is about 30 to 40 amps.
