I can't begin to tell you how many times I've had to manually trace circuits, making my own schematics because "we don't provide that information". For something as simple as a battery charger, it isn't rocket science. The circuit boards are generally old tech (discrete components on boards with single side traces), and the parts are almost universally "off the shelf", even when they put a "proprietary" number on say a transistor. The tough part is when a banded resistor smokes and you can no longer read the colors. Sometimes an online search on a major component electrically nearby can yield a 'standard circuit' which at least gets you in the ballpark for a replacement resistor, or capacitor, or even an upstream or downstream transistor.
Most of these charger boards are simply voltage controls to turn off the charger when the battery is fully charged, to keep it from overcharging - a common problem with standard transformer only chargers where as the current decreases, the voltage can creep to well over 8v on a 6v charger, or over 15 on a 12v charger.
I've worked on a few. If you can list a make and model, I may have already drawn out a circuit. If I can find one useful to you in my workbench paper pile, I'd take a picture and send (post) it.
