This is exactly why the zener must be rated at the above specified voltage for generating a constant 14. 1 V at the emitter side and across the connected 12 V battery. While charging the battery when the battery terminal voltage reaches the 14.1 V value, it reverse biases the emitter of the 2N6284, which shuts down the conduction of the ...
How to Design a Three-stage Battery Charging Circuit | Custom
In the float stage, the charger tries to maintain the fully charged battery in the same state indefinitely. Here, voltage is reduced and a current of less than 1% of the battery''s capacity is applied. You can leave battery charging in this state forever and no harm occurs to the battery.
