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 ## Frequently Bought Together - Q-TECH Battery Load Tester 100 Amp 6/12V with Metal Switch - EZRED SP101 Battery Hydrometer, Factory - LubriMatic 75-033 Battery Filler w/ Rubber Spout, red, 1 Count (Pack of 1) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/166070547-battery-load-tester-100-amp-6-12v-with-metal-switch](https://www.desertcart.ph/products/166070547-battery-load-tester-100-amp-6-12v-with-metal-switch) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-09-11*
