the second stage of battery charging. where the voltage remains constant and current is gradually reduced as resistance in the circuit increases. this stage continues until a full charge condition is sensed. During this stage, the charging voltage is typically highest, from roughly 14V to 15.5V
Why does output voltage drop when charging battery? [closed]
The ''battery charger'' in question is an unregulated, full wave DC power supply that utilises a transformer having a centre-tapped secondary, a pair of diodes and a filter capacitor. At no load, the filter capacitor holds the DC voltage close to the peak secondary voltage
Is power consumed from battery to run the phone when charging?
This doesn''t really answer the question of "does it use battery or pass-through from the charger when the charger cable is plugged in". And the answer is, it depends on how that particular phone was designed. Although I presume most use a pass-through and then ...

Using Laptop While Charging: Bad?
It''s fine to plug in your computer and use it while the battery charges. However, every time a battery is recharged, its lifespan drops a little. Modern devices use electronic controllers that stop charging the battery when it''s full, though. The current bypass the battery and runs the computer directly.

Discharge and Charging of Lead-Acid Battery
When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby reduces the amount of acid in the electrolyte. The sulfate (SO 4) combines with the lead (Pb) of both plates, forming lead sulphate (PbSO 4), as shown in Equation.
