Product requires a brand new battery to perform accurate test on old batteries. This was confirmed with the manufacturer. But it is not stated as such in the user manual.
The readings it produced without first testing a new battery indicated that my 6 year old batteries had more capacity than they were ever designed to have. And not just a little more, they are 28Ah and this tester tested them to be 38Ah.
The manufacturer claims that the tester is a "professionally accurate reserve capacity battery load tester" "quick and accurate results". But it does not provide accurate tests without having a new battery to test an old battery.
