Think if you have only DC voltage and charge the lead acid battery, we can do it by giving that DC voltage to a DC-DC voltage regulator and some extra circuitry before giving to the lead acid battery. Car battery is also a lead acid battery.
This circuit can be used to charge Rechargeable 12V Lead Acid Batteries with a rating in the range of 1Ah to 7Ah. How to Recharge a Lead Acid Battery? Lead Acid Batteries are one of the oldest rechargeable batteries available today.
Lead Acid Battery Lead Acid Battery is a rechargeable battery developed in 1859 by Gaston Plante. The main advantages of Lead battery is it will dissipate very little energy (if energy dissipation is less it can work for long time with high efficiency), it can deliver high surge currents and available at a very low cost.
The battery's condition is dependant on the specific gravity of the sulphuric acid electrolyte. Of course the 6 individual 2V cells in each battery share the same electrolyte which is why they can be charged in series but separate batteries can't.
A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions. Chemical reactions take place at the electrodes:
It is normal to charge lead-acid batteries in series. As they are used, the cell voltages will change, which is why they are not charged in parallel. If they were charged in parallel, the one with the high voltage wouldn't get much current, and the one with the low voltage would get too much current.
