The tester was purchased by me solely for testing the state of charge of the battery. That fully charged batteries are not displayed with full bar number, resulting from the lower cell voltage. This is not problematic, because, after all, wants to inform the discharge of the battery itself. There is, however, precisely the hare in pepper. The capacity of the discharged battery is still indicated by a bar under "good", which can lead to serious error. Ultimately, are testing all three bars available, which in my opinion does not permit prediction of how long the battery could be to use before charging.
