Review on NEXAS All System Code Reader Car Diagnostic Tool with ABS EPB Oil & Engine Reset, Autek 919 Car Diagnostic Scanner, Full OBD2 Check Engine Code Reader for All Cars, Auto-VIN Free-Update [Enhanced Version] by Charles Jenkins

I bought this tester some time ago, used it several times. I keep getting different readings from the same battery for SOH and SOH and 95% of the time it says "REPLACE". I have the impression that these people get a commission from the battery manufacturer. These testers use the same electronics and user interface in comparison (another clone is Ancel). A few days ago I checked my battery and got 40% SOH because most of the time when I drive short distances the battery doesn't get a chance to get a decent charge so I charged it for 2 hours and guess what, the SOH went up 85% without asking for a replacement, but that's ancient history today. Hey Quicklynks, conductivity is independent of charge, you can have 100% SOH zero charge, that's how a good capacitance meter should work!
