## Questions & Answers

**Q: This is the same unit they sell at harbor freight for 20 bucks right down to the switch, do your self a favor and buy the schumacher instead. tom**
A: Everything I purchase at Harbor freight does not last .so I think they sell seconds ..

**Q: Is this made in america**
A: i'm sorry to say, this is not made in america.  that was the first question i had when i went to replace my old one.ther are only a few that are made in usa and they are more than $300.  so they got us over a barrel, you buy this one for under $50 or the next one up is $300.   that's what they mean when america does make anything anymore.  we do make stuff, but its huge money and priced right out of the market.  the us govt needs to step in, tax the crap out of this south east asia stuff so the price would be $150, then the us companies could compete cause they could sell alot more at a lower price.  but the us companies dont see those kind of sales numbers, so its hard to compete in a free trade market.  so, all in all, the answer is no.

**Q: Is the switch momentary or does it stay on?**
A: The switch is just to test the load on the battery it is spring loaded and stays in the off position .

**Q: Will this device measure amperage in 6 & 12 volt deer feeder batteries?  We have batteries that show good voltage but don’t work. Need to check amps.**
A: It doesn’t measure amps. It puts a 100 amp load on the battery and you can see how much the voltage drops.

### ⭐⭐⭐⭐⭐ handy tool to have and it is priced very good
*by P***R on August 30, 2013*

I have used this type of battery tester for years, mine disappeared some time ago, so this was a replacement for it. I got so tired of taking batteries to the parts house/store to have them check them for me. I have looked to buy another for some time but at the parts house/store they are way to expencive. I decided to take a look on Amazon and as soon as i found this one I bought it due to it is OTC brand, a brand that I trust and exactualy like the one that I used to have and that is was half the cost shipped then at any local store, including Harbor Freight, which by the way told me (local store) they do not carry them even though they show them on there website... If you are looking to own a battery tester that will last dang near forever, but this one. I used one just like this one for years in an auto repair business.... Buy it and never look back, well unless zombies are chasing you.
