Commercial vehicle battery testing and maintenance

By Team Writer / August 19, 2019

The electric systems in trucks are more complicated and computerized than ever before, with a wide array of parts controlling a broad range of systems. It is essential for vehicle fleets that all electrical systems have a steady supply of voltage, and this comes down to the battery. Servicing the battery properly prevents issues that would disrupt this system. First, know what type of battery you have, as this will impact their optimal usage and maintenance. Don’t allow batteries to drop below 10 volts from long term storage, or try to start vehicles with low charge batteries, as this can damage batteries, motors, and cables. Test each battery thoroughly when vehicles come in for maintenance, as this gives the technician the information they need to make a correct decision. Perform load tests correctly, and charge the batteries correctly based on their type. Keep batteries fully charged by employing amperage alternators or boost charge batteries while performing maintenance. Don’t skimp on the cost of a good battery, and always follow the manufacturer guidelines in care and use of the battery.

Key Takeaways:

  • When a truck comes in for periodic maintenance, technicians should test each battery to look for consistent tested values or to see a reduction in previous performance.
  • Charging systems on all vehicles usually operate at 14.20 volts; the charging system output amperage is what differs.
  • The service methods for different types of batteries are basically identical.

“Knowing the proper servicing procedures can help prevent battery issues that can result in unplanned downtime and lost revenue.”
