Part 4: Turbo Mode – Using the "Boost" Feature Correctly

The "Turbo" setting is why people search for the instruction link. Used improperly, it will fry your battery.

When to use Turbo Mode:

  • You need to start an engine immediately.
  • The battery is above 6 volts (do not boost a completely dead 2V cell).

The Official Turbo Procedure (from the manual):

  1. Connect clamps as usual.
  2. Set the mode to "Boost/Start" .
  3. Attempt to start the engine for 3-5 seconds maximum.
  4. Wait 2 minutes before trying again. The Turbo 4 needs time to cool its internal rectifier.
  5. After the engine starts, immediately switch the charger to "Off" or "Low" to prevent overcharging.

Warning: Leaving the charger in Turbo mode for 20+ minutes without a load will boil the battery dry. Selmar Turbo 4 charger AC power adapter User
