Battery Sulfation

What is sulfation?

During normal battery use, sulfate crystals gradually build up on the battery’s lead plates. This is called sulfation. When a battery is charged, some of the sulfate crystals which have accumulated on the plates are returned to the battery’s electrolyte solution. However, there is still some sulfation which remains. While some battery sulfation is unavoidable, there are factors which can accelerate sulfation, leading to battery failure and capacity loss.

Common factors include...

Battery Inactivity: The longer a battery sits in a discharged state, the harder sulfate crystals will become. This means that fewer crystals will be returned to the electrolyte during the next charge cycle.

Opportunity Charging: Although it is common to charge batteries for short periods of time, this will lead to battery performance issues. Repeatedly failing to fully charge or discharge a battery will cause more and more of these sulfate crystals to accumulate, and the battery’s capacity or run-time will become diminished.

Low Electrolyte Level: When a battery’s electrolyte level is depleted, the battery’s plates are exposed to air and sulfation occurs immediately.

Reversing Battery Sulfation

The Xtender Battery Regenerator uses a six stage process to dissolve the hard sulfate crystals and return them back to the battery’s electrolyte solution. Through discharging and high-frequency pulsation phases, the Xtender successfully prolongs the lifespan of lead-acid batteries, while cutting costs on maintenance and eliminating man hours.
