FAQs about Lead-acid battery desulfurization circuit
How does a lead acid battery desulfator work?
Brief Description. Most lead acid battery desulfators out there use a flyback design with inductors. While this does work, the inductor can only hold so much energy each pulse. If the battery has a high resistance, that energy won't be absorbed very well and will show up as a very high voltage spike on an oscilloscope.
Can a pulsing method extend the life of a lead acid battery?
In this instructable a novel (resistive) pulsing approach is described for driving the lead-sulfate back into solution that is faster than the more traditional inductive method. Sulfation is not the only aging mode in lead acid batteries, so while desulfation may extend the life, it will not do so indefinitely.
Why is sulphation a problem in a lead acid battery?
Sulphation in lead acid batteries is quite common and a big problem because the process completely hampers the efficiency of the battery. Charging a lead acid battery through PWM method is said to initiate desulfation, helping recover battery efficiency to some levels.
How sulfation reversal is possible in lead acid batteries?
Several manufactures have developed ways for sulfation reversal in lead acid batteries in recent years with different successes. Some pulsed charge appears to be the basis of the working processes. This is contrary to ordinary charging techniques with a steady voltage in most cases.
What is a desulfurization desulfator circuit?
There are some very popular kits in the circuit I made. Description of the circuit; The desulfurization Desulfator circuit (also known as Regeneration or electrolyte stratification) offers a way to bring dead batteries back to life and renew tired batteries.
Does charging a lead acid battery sulfate a battery?
Charging a lead acid battery through PWM method is said to initiate desulfation, helping recover battery efficiency to some levels.
