Bulk Charging – The first charging stage. The charger applies an increasing voltage to deliver maximum current to the battery. This rapidly replenishes the charge. Absorption – After the bulk stage, the charger voltage is held constant at a slightly lower level as the current gradually tapers. This saturates the battery.
The multi-stage charging process typically includes three stages: bulk, absorption, and float. Let''s have a look at these stages in a little more detail; During the bulk stage, the charger delivers a constant current to the battery until it reaches around 80% of its capacity. This stage is intended to charge the battery quickly and efficiently.
