This article is to explain the fatigue lead-acid batteries used in pulse charger circuitry. The circuit is simple but effective. For your more thorough grasp of this principle, we suggest that you can know more about some of the important components of the circuit, such as: BC546 . If the battery has a rest for at least 1.8 volts / cell and cell short circuit, desulphation plate can be done. This circuit is an additional modification, and a normal part of the charger, which is responsible for the problem of sulfuric acid. The object is to make the battery voltage is not high enough boiling sulfate solution or melt of the battery. This is accomplished by applying a high voltage short time, let the battery rest. Pulse short range of about 0.5 s / 3 s off and long pulse range is 1.4 s / 2 age. These times can vary depending on component tolerances. Began long pulse and if you find a "boiling" (more than normal charge) in the electrolyte switch to short pulses. Do not leave this process unattended, at least until you know how your particular version of this project demonstrates. I created version. Some 10 years ago, this circuit one has tried it but I believe that someone could be further improved.
