Review on Multifunctional Capacity Indicator Lead Acid Motorcycle Tools & Equipment in Diagnostic, Test & Measurement Tools by Justin Kautzman

There is a guy here who left a 1 star review because the voltage drops and fluctuates when he presses the pedal, ignore him as he obviously doesn't know enough about batteries, to understand what is called a voltage dip. These battery gauges are designed to show you open circuit voltage condition and capacity and they are as accurate as possible, with the same accuracy as my multimeter, cell meter and lipometer (actually all of these testers use identical components in all of their readers). Fact that I can use it as a capacitance meter or volt meter gives 2 thumbs up from me.
