FAQs about Lead-acid battery sulfation repair circuit
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.
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. Sulphation is a process where the sulfuric acid present inside lead acid batteries react with the plates overtime to form layers of white powder like substance over the plates.
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.
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.
How does crystallized lead sulfate affect battery performance?
The crystallized lead sulfate not only does not participate in the reaction, but also adsorbs on the surface of the electrode plate, which increases the internal resistance of the battery and affects the charge and discharge performance of the battery and the battery capacity3.
How does a battery desulfator work?
A battery desulfator is an electronic device that reverses the sulfation process in lead-acid batteries, restoring their capacity and extending their lifespan. It works by sending high-frequency pulses through the battery, which breaks down the lead sulfate crystals and allows them to be reabsorbed into the electrolyte.

For a 4.2 V LiIon cell, the useful voltage range is 4.1 V to 3.0 V – a cell at 4.2 V quickly drops to 4.1 V when you draw power from it, and at 3.0 V or lower, the cell's internal resistance. Now you know what it takes to add a LiIon battery input connector to your project, and the secrets behind the boards that come with one already. It's a feeling like no other, taking a microcontroller project with you on a walk as you. Now, you've got charging, and you got your 3.3 V.

Then this is a closed circuit that will charge the capacitors. (sorry for the ascii circuit, the -| |- are capacitors, the MMM is a resistor, and the (-+) is a voltage source). Your argument is: If the circuit is open, the current must be zero. Consequently the field must be zero.
Will a capacitor be charged if a switch is open?
The circuit is open since the switch is open. My book says that the capacitor will only be charged when the switch is closed, but I don't see why this is true. I would expect the capacitor to be charged a little - not as much as if the circuit is closed, but still charged none the less.
