Review on 🔋 KZYEE KS21 Battery Tester - Accurate 12V Analyzer for Auto Car Batteries, Health Fault Detection, Cranking & Charging System - 100-2000 CCA, Digital Load Testing by Peris Holland

I dreamed of a battery that seemed to be running low and wanted to know the true state. The result of the stress test was not clear. Purchased the KS21 analyzer after reading about the benefits of testing with conductive test equipment to get a more accurate indication of actual battery health parameters. Took the battery to the local NAPA with a question for a warranty replacement. NAPA staff tested the battery with their impressive professional analyzer. The results from their analyzer were almost identical to the KS21 test and I was able to get a replacement under warranty. Interaction with Kzyee USA customer service was very positive and showed that the representative was committed to providing excellent product support. Testing with a good conductivity analyzer is the best way to accurately determine a battery's condition and reliability.
