BZI Batt-Recon Automotive / Industrial Battery

De-Sulfation System

Bravo Zulu International Ltd., (BZI), has developed and introduced the PIC based Model 4800P AGC Lead-Acid battery de-sulfating system. This is the first commercially viable lead-acid battery de-sulfating system, capable of de-sulfating large motive batteries in as little as one hour.

The BATT-RECON Model 4800P AGC Universal System, has a digitally controlled, high power pulse width modulated process with our new Patent Pending “Multi-Channel ” design. Our unique “Variable Power Pulse Technology sm” allows you to control the “Power of the Pulse, ” and de-sulfate AGM, VRLA or Maintenance Free batteries.

The PIC based Model 4800 AGCP has a Dual Channel operating mode allows the machine to deliver twice the operating power over our previous single channel system. This greatly reduces the time to de-sulfate a battery.

This new machine is a breakthrough in technology allowing for the first time, a commercially viable method to remove sulfate buildup on the inside of a battery's lead plates.

PWM is the basis of this new and exciting product because the generation of high amplitude, low frequency electrical waves, provides an “ultra-sonic” type of cleaning action to the battery's internal plates. The PIC based Model 4800P AGC PWM ultrasonic process is primarily designed for preventive maintenance to remove Level 2 sulfates before they become harmful Level 3 sulfates. If Level 2 sulfates can be removed on a preventive maintenance basis to a like new or “Year Zero Impedance” condition, then the battery's life expectancy will multiply several times over. In addition, the Model 4800P AGC has been successfully proven to restore most batteries that were previously discarded, to a “like new” condition.


The act of transferring electrical energy from the electrolyte solution causes the sulfur ions to attach to the internal lead plates of the battery. These sulfur ions form a layer or coating, which prevents the efficient transfer of electricity in and out of the battery.

When the sulfur ions are attached to the lead plates, they are characterized as Level 1 , Level 2 or Level 3 sulfation.

Level 1 sulfation

is normally removed and restored to the electrolyte solution by conventional battery charging systems.

Level 2 sulfation

is typically found in a crystalline form and is aggressively attached to the lead plates. Normal battery charging does not remove Level 2 sulfation, reducing the battery capacity.

  • Level 2 sulfation causes lengthened charging cycles, incomplete charging and poor battery performance causing premature replacement.
  • Level 2 sulfation can be easily removed from the lead plates by using the BATT RECON system, thus restoring the battery to a “like new” condition.
  • Level 2 sulfation, left untreated, will eventually form into Level 3 sulfation.

Level 3 sulfation

results from the continued accumulations of Level 2 sulfation, which imbed sulfate crystals into the battery plates. Once imbedded, sulfate crystals are more difficult to remove and cannot be removed by a conventional charging system! Unfortunately, the removal of Level 3 sulfation also tends to damage the porosity of the plates, because the Level 3 sulfate crystals literally pull the lead surface with it during the de-sulfating process. Therefore, PREVENTION is better than a cure! We recommend that you de-sulfate every six months to prolong the life of your batteries.
