Lead acid battery is a rechargeable battery developed in 1859 by gaston plante.
It expresses approximately the change in capacity of rechargeable lead acid batteries at different rates of discharge.
It is based on the well known type lm 3914 led display driver from national semiconductors.
Balance pin 5 is used as the reference voltage for regulating the current.
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.
To use this circuit to monitor a 6v battery substitute d1 for a 3 3 volt zener diode and adjust r1 accordingly.
Charging a lead acid battery through pwm method is said to initiate desulfation helping recover battery efficiency to some levels.
This lead acid battery charger circuit is simple to build and can be fit in a small box.
Below is a lead acid battery charger schematic using the famous ic lm 317.
Responsible for this behavior is peukert s law wilhelm peukert 1897.
This voltage is compared with the divided battery voltage at the wiper of p1.
