The natural method of passive balancing a string of cells in series can be used only for lead-acid and nickel-based batteries. These types of batteries can be brought into light overcharge conditions without permanent cell damage. When the overcharge is small, the excess ener gy is released by increasing the cell The battery charger and
Moreover, some lead acid (LA) batteries found in solar applications are deep cycle batteries capable of surviving prolonged, repeated charge cycles, in addition to deep discharges. A good example of this is in deep sea marine buoys, where a 10-year deployment life is a prerequisite.

The battery charging circuit is completed when the relay flips its contacts to the Normally Open (N/O) position. Crucially, T2 simply has to be turned on for PB1 to begin this process; it only needs to be pressed briefly. Automatic Shut-Off: The voltage drop across R5 progressively drops as the battery charges.
Input sources are as wide as they are variable, but some of the more complicated ones that deal with battery charging systems are: high powered wall adapters with voltages spanning from 5 V to 19 V and beyond, rectified 24 V ac systems, high impedance solar panels, car, and heavy truck/Humvee batteries.
Nevertheless, like their Li-Ion counterpart, LA batteries are sensitive to overcharging, so careful treatment during the charging cycle is very important. Current integrated circuit (IC)-based solutions cover just a fraction of the many possible combinations of input voltage, charge voltage, and charge current.
