I ordered the part because I thought my car battery was after 5 years at the end. But by the precise digital display I could see that my battery only very minimal loses capacity - 2 decimal places. I built an Excel spreadsheet, and as I enter the measured values, and so I could see clearly that the voltage drops only very minimal, or I could it calculate when I have to drive my car so that the battery is not completely empty , Disturbing is the length of all cables - that could be twice or 3 times as long. Otherwise a super part - because it after the comma provides the accuracy 2 Set wonderful comparison.
