DY220B 12V Battery Analyzer Automobile Motorcycle Storage Cell Tester Digital Car Cranking Test Diagnostic Accessories


This battery tester is used for testing the conditions of the 12V lead-acid starting battery: cranking system and charging system.

It comes with a large backlight LCD screen and it supports classic touch-tone to help you read and operate more efficiently.

It utilizes the 4-wire Kelvin method to complete the collection of a series of complicated data for calculating every testing data with a build-in precise circuit and improved digital processor.

Moreover, some circuit improvements including polar reversal protection, over-voltage input protection, and loose lead detection, ensure safety and convenience during testing.

This is a must-have tool in the fields of battery sales, vehicle repair and battery inspection equipment system.
