Lead acid batteries are comprised of a Sulphuric acid solution electrolyte, a sponge metallic lead anode and a lead dioxide cathode. The result of all the reaction is a potential difference between the two plates where the positive plate gives up electrons and the negative plate gains them in equal numbers.
To protect the batteries for the fear of being destroyed, the circuit provides the detection of discharge. On order to control the discharge of the battery, a stable voltage in a circuit is required to check the voltage. Lead acid batteries are being used in several industries because they are tried and tested, robust, tolerant to abuse and overcharging, low internal impedance, can deliver high currents, wide range of capacities and sizes, supplied worldwide, indefinite shelf life if stored without electrolyte, reliable, and low cost. Lead acid batteries often fail prematurely due to over-charging, under-charging, deep discharging and low electrolyte level. 12v battery charger circuit auto cut circuits, 12v battery charger circuit with auto cut off gallery of electronic circuits and projects providing lot of diy circuit diagrams robotics & microcontroller projects.

Here is the circuit diagram of a battery eliminator circuit that can be used as a replacement for 9V PP3 batteries. This is the circuit diagram of a very powerful and efficient Ni-MH battery charger using IC LT4060 from Linear Technologies. Because of the chemical combinations, this heavy metal element is toxic and disposing it improperly would be hazardous to the environment. However, there is a limitation in the length of time for the reaction to produce the cell voltage.
Since the lead acid battery has a voltage of 12 V, it is not allowed to be rated below 10.8 V. This can done using the IC1 LM723 which is a monolithic integrated circuit programmable voltage regulator, assembled in 14-lead dual in-line ceramic and plastic package. Also it is gives you enough time to get ready for a recharging or buy a new one in advance.
I have a bank of 4 all tied to a 400 watt wind turbine and with no load I get a discharge, can you help me out. All of these can lead to sulphation of the plates which leads to high internal resistance and eventual failure. When the battery discharges, some of the lead from the plates combines with the electrolyte to make lead sulfate (PbSO4) which builds up on the surface of the plates as crystals (as electrons leave the battery as electricity).
Mechanically, the lead acid battery is made of a series of identical cells where sets of positive and negative plates comprise each cell.


The voltage will remain constant without the presence of connection between the two plates. It can provide internal current limiting and an external NPN or PNP pass element may be used when the output current exceeds 150 mA. Using wooden pallets is the best storage method since it will not allow damp paths, will not conduct, and will provide good air circulation. Normally, this process is regarded as irreversible but this circuit is claimed to reverse the process by applying high voltage pulses to break down the lead sulphate compounds. The chemical reaction will be able to continue the electrons to flow through the circuit from the negative plate to the positive in the event that a load is placed between the positive and negative plates.
Lead acid batteries should never run flat and the maximum recommended discharge is 75% of the total. A refreshening charge once every two months or more is recommended by most manufacturers during storage. The circuit is essentially a high-voltage pulse generator which is powered directly from the battery in question. When the battery is next charged this process is reversed with the lead sulfate crystals breaking down - returning the lead to the plates and restoring the electrolyte to its original composition.
This signifies that the minimum charge remaining on the battery should be around 25% before recharging.
Thin electrode plates allow a lot of energy to be discharged quickly for a short period of time like in car batteries. If the battery is badly sulphated, it will be necessary to connect it to a low power charger as well, say 2A.
There are always one or more negative plates than positives because the arrangement of the positive plate is always in between the negative plates. The battery will fail to produce any current when the supply of electrons becomes depleted.
Lead acid batteries should always be regularly charged even on its idle state once it has been filled with electrolyte. Thick electrodes in lead acid batteries can tolerate discharges better than thin but at the expense of producing heavier batteries. This is a particular problem when batteries are left discharged for long periods of time and when they are deeply discharged.Lead sulfate on the plates of a battery acts like an insulator reducing the plate area in contact with electrolyte.
The cause of this depletion may pertain to the electrolyte being turned mostly into water or the active material on the negative plate has been used up.
Over time this build up of lead sulfate crystals will result in a battery which cannot hold much charge - i.e. The efficiency of the battery system depends on the heating levels of the chemical process wherein greater heating means the battery is quickly exhausted. The 555 timer is connected as an astable oscillator with its output frequency set by R1, R2 and C2. The sulphuric acid has the ability to distribute itself very evenly throughout the electrolyte in the battery due to its instability.


The self discharge rate is a measure of how much the batteries discharge by them and is managed by the metallurgy of the lead used inside and the construction of the battery.
IC1 operates as a voltage comparator which compares the value of voltage between pin 4 and pin 5.
Its output pulses drive the gate of Mosfet Q1 which turns on to charge inductors L1 and L2. It can also be used every few months to keep batteries in the best possible condition all the time.
This will always to an even reaction between all the plates by producing current and voltage. When the voltage in pin 4 is larger than the voltage in pin 5, the output in pin 9 becomes low.
At the end of each pulse, Q1 turns off and the inductors develop a high-voltage high-current pulse which is applied across the battery via fast recovery diode D1 and the 100µF capacitor. Desulfation will not bring batteries with a shorted cell or worn out plates back to their former glory, but it is a valuable tool for anyone depending on battery storage for power who cannot afford to buy new batteries.When lead sulphate crystals build up on the lead plates, it is not an easy task to remove them and thereby recondition the battery. Both plates are turned into lead sulphate by the chemical reaction between the lead dioxide at the positive plates, the spongy lead at the negative plates, and parts of the electrolyte. But when the output in pin 9 becomes high, the LED will turn on as a result of the conduction of Q1. Breaking down hardened crystal build up and dissolving cystals back into the electrolyte requires a charging voltage much higher than would ever be used to actually charge the battery.
The regulation of the circuit requires an external power supply which can be regulated with a value of 10.8 V. But, if you were to put this constant high voltage through the battery it would overheat, release gas, and could potentially explode. Therefore pulse conditioning is used to give very short blasts of high voltage sufficient to shift the lead sulphate crystals without overly raising the temperature of the battery as a whole.Every lead acid battery has a resonant frequency at around 2 to 6 megahertz. If pulses of electricity (high frequency, high voltage, but low power) are sent into the battery, rhythmic beating (resonance) of the plates causes the crystalline deposits to break up and the sulphate returns to the electrolyte solution.This process takes three to four weeks typically during which time the battery must be trickle charged (in parallel with the desulphator) so that the battery ends up reconditioned and fully charged. Below is a video showing the lead plates inside two identical batteries - one which has been desulphating for three weeks, and one which has been left in its original sulfated condition.Note that the voltage measured across the battery terminals will drop as the desulphation takes place as the internal resistance of the cells is reduced by the clearing of the crystals on the lead plates.
At the same time, the amount of charge that the battery can hold will be increasing.Build a Battery DesulfatorA DIY battery desulfator circuit originally published in the US-based Home Power magazine has been successfully made for many years all over the world.
