In this article we will discuss about the working of lead-acid battery with the help of diagram. When the sulphuric acid is dissolved, its molecules break up into hydrogen positive ions (2H +) and sulphate negative ions (SO 4– –) and move freely.
The 5 useful and high power lead acid battery charger circuits presented below can be used for charging large high current lead acid batteries in the order of 100 to 500 Ah, the design is perfectly automatic and switches of the power to the battery and also itself, once the battery gets fully charged.
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.
8.4 How to Set Up the Circuit. Lead acid batteries are normally used for heavy duty operations involving many 100s of amps. To charge these batteries we specifically need chargers rated to handle high ampere charging levels for long periods of time.
