The PMBC Series Battery Charger Maintainer is the best choice to provide proper battery support, the most important step to the vehicle before beginning any Diagnostic Calibration Reflash or electronic scan process.

Standard Battery chargers or a jump box are not recommended as they will not provide the proper battery support to the vehicle. Battery chargers can overcharge and “cook” a battery, and jump boxes can go dead or lose their charge over time.

A quality battery voltage maintainer provides uniform voltage to the vehicle for longer
periods of time compared to an unsupported battery. The bottom line is to make sure that before you begin any diagnostic or vehicle electronic scan using the PMBC Series, the car has proper battery support to provide the best possible outcomes.

When vehicle voltage levels fall below the normal levels, diagnostic results are no longer accurate. Fluctuations in battery voltage can also cause additional codes to appear. If an unsupported battery fails, or fluctuates, during programming it can cause the programming to fail, which can be very costly.
