Intelligent chargers may also have a Power Supply feature which provides a nominal 13.7V. This feature, she notes, will maintain the vehicle’s power during extended service procedures, allowing the technician to diagnose the vehicle problem or for re-flashing the ECU, becoming the “heart” of the vehicle during these long procedures.

Some units also provide a memory saver function for switching out a battery without losing pre-sets.

  • Parallel chargers. These can be used for charging multiple batteries. Parallel chargers are not stand-alone; a bus-bar is needed to charge multiple batteries. Some of these units are hard-wired and may run on a 240V line. They have multiple charge rates that are set by the technician.

Applications for this style of charger would include any application where large numbers of batteries need to be charged, rejuvenated or maintained, says Cottle.

  • Gang charger. The charges have several distinct circuits, each with its own clamps and settings. These would be used for charging or maintaining a smaller number of batteries, Cottle says. Rarely would they be used for rejuvenating a battery.
