ANCEL BA101 12V 100-2000 CCA Car Battery Tester Charger Tools

OK but…

The Ancel BA101 gives a reasonable battery health report but the instrument needs a lot of input data off the battery label. If the battery is buried somewhere in the back or under the car, it may difficult to observe the input information required. Also, the BA101 seemed to be unable to check a battery jumper unit. Maybe it did not like the battery polarity protection feature or something. The battery jumper unit also buries the battery under a casing, so no convenient access to the battery specification data to input to the BA101. I have owned the BA101 for about a week. Other than the above short comings, the BA101 seems to give accurate battery health assessment.
