Built-in battery load test

The Built -in computer controlled battery load test will test your battery once every 21 hours and display the results as; Green LED for battery Ok or Red LED for check battery. The load test regime consists of the following:

  1. The microprocessor measures the battery voltage and records the result
  2. The microprocessor tests the battery with a 30 amp load for 5 milliseconds
  3. The microprocessor measures the voltage at the end of the 5 milliseconds and compares it to the initial voltage
  4. If the voltage drop is less than 2 volt the Green LED will glow
  5. If the voltage drop is more than 2 volt the Red LED will glow.

The microprocessor onboard FAB also independently monitors the internal resistance of the battery and adjusts the pulse output to minimize desulfation time and maximize battery performance and life. Unlike other pulse products Megapulse therefore does not just pulse the battery and hope for the best but it constantly interacts with the battery and reports the results to the user

Sealed case design

Megapulse FAB-MK4 is water resistant so it can withstand engine washing and short river crossings.

Electronic dual activation switching

Megapulse FAB-MK4 can be easily and quickly switched from low activation to high activation, simply place the supplied magnet (or any magnet) on the spot marked "magnet", once the LED confirms the action, remove the magnet. Unlike other pulse products, Megapulse FAB-MK4 can be used on all applications whether it is engine starting or auxiliary applications without the need to purchase a separate unit.
