The battery voltage becomes smaller after charging
Charging a larger battery takes more time than charging a smaller cell, and vice versa. If the Ah rating varies too far, don''t charge (above 25 percent). Although a high-wattage charger reduces charge time, there really are limits to how quickly a battery could be charged. Extremely fast charging could be stressful to the battery.

electromagnetism
When the battery is disconnected, an ideal voltmeter connected across the connecting wires will continue to read the battery voltage since that is the voltage the capacitor and connecting wires charged to. Electrons didn''t need to leave the negative plate to establish this voltage - the charge distribution giving rise to this voltage was already there.
