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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***L on November 30, 2025* El producto esta bien pruebas de bateria sin problemas solo que el cable y pinzas se ven muy fragil los cables muy cortos .

It is accurate and does exactly what it is supposed to do. Cables are short but so are most load testers. She warms up good as they do but the coil handles it well. Would recommend.
