Review on ANCEL BA101 Professional Automotive Motorcycle by Shawn Quick

This tester is quick and easy to use as long as you read the instructions and know you can't use the 'quick test' feature on a starter battery, which is rated based on CCA (or any standard other than Ah). Instead, you must use the "Battery Out of Vehicle” menu item. no sweat I had bought two identical starter batteries at the same time and suspected I had a problem with one of them. I checked both batteries and the analyzer said both are fine but need to be charged. I placed each battery on the charger until my charger indicated a full charge. I used the analyzer after charging and it showed good battery and over 98% charge each. I then placed both batteries on a shelf (not connected to a load) and tested again with the analyzer a day and then two days later. The analyzer showed a small drop in charge in one healthy battery, but the charge in another battery dropped to 50% within two days of no load. However, the analyzer showed that it was a good battery that just needed to be charged. My conclusion from this is that the analyzer will not diagnose a battery that is not holding a charge. It seems to show the percentage of charge and battery voltage well. It lists the available CCA for my starter batteries, but I wonder about the accuracy because it always lists more than the rated CCA, even with my battery not holding a charge. The bottom line is that I expected an accurate diagnosis as to whether or not my battery would fail in service, and I didn't get one. Since this tool is easy to use and still of limited use to me, I give it a few stars.
