Hey fella's electronic load tester do actually work really well if used correctly batteries that are What most people state as charged is mainly surface voltage lots of show not much go or ran flat will actually give false readings on the electric load testers, so if you head into a battery place to get your batteries checked and stop the vehicle for the test it will be in correct, that's why personalty i prefer to test with the big carbon pile load tester and then use the electronic load tester as the carbon pile load tester has already removed any surface voltage from the battery, if the battery permits i may even get the trusty hydrometer out but maintenance free batteries are slowly putting a stop to that, i could write a small essay on batteries but i haven't got that much time in the day too many machine and vehicle to fix electrical issues on
