Why Use a Battery Tracker? My car has voltage indicator
Aside from giving Voltage Reading and providing Starting and Charging system tests, the Battery Tracker is useful in many other areas:

  • Monitor level of Parasitic Draw, how fast the battery discharges
  • Be alerted of battery's low energy before coming back to dead battery
  • Monitor vehicle's charge level over 31 days and history of when driven
  • Verify vehicle's charging system works; great for home mechanics
  • Racers: get battery status and alternator output during time on track
  • Total Loss systems: document voltage decline while in operation
