This 24V to 36V linear battery charger is long overdue. While this is an old circuit technique, it is optimized for charging higher voltage lead-acid battery packs, and could be used on other types of ...

Did you know that regularly charging your car battery can extend its lifespan by two or even three times longer than usual? It also has the potential to revive a dying battery, saving you from having ...

D1 is the voltage reference zener. Tied to this is a string of divider resistors (R2-6) that set the various fixed voltage levels. R7 & 8 form a voltage divider to that divides the battery voltage by ...
