BEFORE YOU START
  • This does not work on damaged batteries
  • For a battery to benefit from the desulfator, it has to be in good condition.
  • The process will eventually enhance its charging capacity and therefore restore its ability to store the right amount of energy. 
  • It's a repeated process as described in the below cycles

When to suspect a sulfated lead acid battery?

  • If stored unused for a long time
  • In vehicles with intensive city use especially with the air conditioner and lights on.
  • In unused equipment
  • If the battery charges too fast
  • If the battery cannot reach a voltage of 14.5V when charging
  • ​If the battery keeps drawing a little current when charged on an automatic charger with the charger never indicating the full charge status

Which batteries can be desulfated with a pulse desulfator?

All lead acid (lead-acid) batteries aged two years or more and still in good condition:
  • Batteries with adjustable electrolyte levels
  • Sealed lead acid, VRLA, gel
  • Calcium batteries
  • Maintenance-free batteries
  • Car, UPS, motorcycle, generator, boat, golf cart, torch light, backup batteries

Lead acid battery regeneration - desulfator cycle

  1. Make sure your battery is charged i.e. that its voltage is more than 12.0 V
  2. Remove it from your car or UPS or at least disconnect it completely
  3. Connect the electronic pulse desulfator wires to the battery terminals, this device requires no external power, it gets powered by the battery itself
  4. The desulfator will recognize the battery voltage and start pulsing the battery
  5. Keep it for 6 hours at least and up to 10 hours.

Lead acid battery regeneration: charging cycle

  1. Take out the pulse generator and plug the battery charger to the battery
  2. Leave it until fully charged
  3. If the battery does not reach the required charging voltage or if it is still drawing a little current, unplug your charger after a few hours and as long as your battery voltage is more than 14V
  4. Repeat the desulfatror / charging cycle described above at least three to four times, meaning during 2 -3 days
