What is the battery saturation voltage
Charging of lead-acid batteries
Lead acid charging uses a voltage-based algorithm that is similar to lithium-ion. The charge time of a sealed lead acid battery is 12–16 hours, up to 36–48 hours for large stationary batteries. With higher charge current s and multi-stage charge methods, the charge time can be reduced to 10 hours or less; however, the topping charge may not be complete.
Module Circuit Design
In a typical module, 36 cells are connected in series to produce a voltage sufficient to charge a 12V battery. ... I 0 is the saturation current from a single solar cell; I L is the short-circuit current from a single solar cell; n is the ideality factor of a single solar cell;

As you can see on the datasheet below for the 2n2222a NPN transistor, the "Collector-Emitter Saturation Voltage" and "Base-Emitter Saturation Voltage" are defined respectively as 0.3 to 1.0 and 1.2 to 2.0. I believe I understand transistor saturation, but whats the difference between Collector-Emitter Saturation and Base-Emitter Saturation?
Current transformer (CT) saturation calculator
Second step is to determine the slope (1/S) of the upper part of the saturation curve, being careful that the curve is plotted on log-log scales with the decade spacing equal on both axes. "S" is defined as the reciprocal of this slope. You should get a slope such that S is in the neighborhood of 15 < S < 25. Note that the result is not very …

The term "Saturation" means exactly the opposite for FETs and BJTs. The flat region is not in saturation for junction transistors. A transistor in saturation would be at the bottom left corner. By "Saturation voltage" they mean the collector to emitter voltage under the given conditions. Usually it is with a forced beta of 10 or 20.

How to Maximize Battery Potential: 7 Charge Types Explained!
As the battery charges, its voltage goes up, and resistance builds up inside the battery. The charger monitors the battery''s voltage and adjusts the charging current accordingly. This continues until the battery reaches the target voltage for the bulk stage. Then the battery moves into the next charging phase – the saturation stage.

Transistor Saturated: What It Is and How to Identify One
The collector-emitter saturation voltage, denoted as VCE(sat), is the voltage drop across a transistor when it is fully saturated. This voltage is typically around 0.2V for silicon transistors but can vary depending on the specific transistor type and manufacturing process. The VCE(sat) value can be found in the transistor''s datasheet.
