## Questions & Answers

**Q: Would this work for a 12v 50 ah battery on ryobi mower? description says "100a load test for 12v batteries; 50a load test for 6v batteries"**
A: The short answer is probably not. The system uses advanced algorithms to test batteries and is designed for specific battery loads which measures internal characteristics of the battery and infers the battery's CCA output and health based on a certain range of battery. Outside that range and the electronic battery tester will be ineffective. Your best bet is to purchase a carbon pile or cheaper resistance type ($25) battery tester for such a small battery. 
Hope this helps.

**Q: Can it be used on agm batteries?**
A: Yes it can use on agm batteries.

**Q: Is it made in USA?**
A: It’s  made in China.

**Q: how many amps load does this put on a battery**
A: 100 Amp fix load

### ⭐⭐⭐⭐⭐ Decent load tester with the old fashioned large resistor
*by M***. on July 18, 2022*

I just don't know how to trust the new compact load testers with digital readouts. According to physics, to load test, you must place a small valued, high power resistor across the two terminals that results in a large amount of current between them, then monitor voltage drop or current and see if the battery can provide a sustained amount of either. This box does exactly that, and the heat you will feel will confirm to you that without doubt, a large amount of power traversed its two terminals. The readings I tried on several batteries (one dead) seemed to confirm the status of each.
