Review title: Bad Diagnosis - Discarded good battery
Product review: I ordered this product to charge my car battery. I had previously used manual chargers on this battery with success. This charger promises automatic capability and diagnostics on your battery. Upon hooking the charger up to the car battery, diagnostics produced an "Open Cell" diagnosis, it would not charge at this point. I replaced with a brand new battery. The new battery works fine in the car. When I hooked the charger up to the new battery to see what it would say, same diagnosis, "open cell". Battery obviously is not the problem at this point. Tried hooking charger up to my lawn mower, same result "open cell". The lawn mower battery has been working fine. I have no option to override the assessment and still charge the battery if I want. I believe the battery I replaced probably was still good. Don't believe this unit diagnosis, costly mistake.
