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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Value for the books *by N***T on April 9, 2026* Low priced that has features of one twice the money.
