Supports common battery rating standards, allowing the figure printed on the battery label to be entered for an appropriate assessment. Displays battery condition and measured voltage with a published voltage measurement range of approximately 6–18V. In-vehicle or out-of-vehicle testing without removing the battery when access permits. Powered from the battery under test, so there is no internal battery to charge before use. Ideal forRoutine battery checks, used-car preparation, seasonal vehicles and confirming whether a starting problem is likely to be battery related.Compatibility and important informationUse the rating printed on the battery and follow the connection instructions carefully. The BT100 is primarily a 12V battery-condition analyser; it should not be confused with Foxwell models offering more extensive 12/24V charging-system analysis.
