Battery desulfurization pulse waveform

How does a battery desulfate?

Here's an excerpt from wikipedia, which says, " Desulfation is achieved by high current pulses produced between the terminals of the battery. This technique, also called pulse conditioning, breaks down the sulfate crystals that are formed on the battery plates. Short high current pulses tend to work best.

What is a battery desulfator?

The desulfator circuit a gadget that feeds the battery regularly with brief yet hard pulses whilst it discharges slightly between the pulses. As far as we know, this is the most efficient technique of breaking down undesirable sulphate crystal deposits and restoring the battery plates to an acceptable level.

Is there a 3rd desulfation method?

There’s a third desulfation method, but it’s not recommended. Both work in the same way. Both have clamps/connectors that attach to the battery terminals and emit a high-frequency pulse across the battery. The pulse of a desulfator / conditioner charger looks something like this: The type of pulse used is the key to how it works.

How does a desulfator circuit work?

The desulfator circuit may be utilized in three distinct ways. The first is for the prevention of sulphation on a battery with little, or no, sulfur in an existing system (for example in a car). By physically hooking up the circuit to the battery with the shortest practicable connections, it is incorporated into the system.

What is the actual desulphating voltage of a battery?

The genuine desulphating voltage is indicated in the datasheets as 29 V. As it may be feasible for a intensely sulphated yet recoverable battery to arc internally if an increased voltage is fed, another SCR circuit could be included around BR2 to stop any voltage greater than 29-30V applied to the battery.

How do I make a desulfator draw a high voltage?

The simplest way to do this would probably be by using a 555 timer and a few other components to send the high voltage pulses into the battery. Generally desulfator circuits draw around 300mA, though it can fluctuate widely depending on the design you use. If it starts drawing >600mA then chances are you're doing it wrong.
