The capacitor charges when connected to terminal P and discharges when connected to terminal Q. At the start of discharge, the current is large (but in the opposite direction to when it was charging) and gradually falls to zero. As a capacitor discharges, the current, p.d and charge all decrease exponentially. This means the rate at which the current, p.d or charge

Charging Capacitors: How Many Can You Power With A 600mAh Battery
Capacitance Value: The capacitance value refers to how much electrical charge a capacitor can store. This value is expressed in farads (F). As the capacitance value increases, the number of capacitors a 600mAh battery can charge decreases because it takes more energy (and thus more capacity) to charge each capacitor.

How long do Capacitors retain their charge?
Capacitors are not the same as batteries. Capacitors begin to slowly discharge immediately after the power source is removed. Batteries can hold that charge for days, weeks, even years depending on the battery type. Or use a 1K 5W resistor across the terminals. Hold the body of the resistor not the leads. Then check with a voltmeter to be sure.

6 FAQs about [Battery filter capacitor is charged]
What are the different types of filter capacitors in battery charging circuits?
There are mainly two types of filter capacitors in battery charging circuits: input filter capacitor and output filter capacitor. The AC voltage across the step-down transformer is rectified and often filtered using capacitors to obtain a regulated DC voltage through a voltage regulator chip to charge the battery.
What is the purpose of a capacitor in a battery charging circuit?
The input capacitor ensures that the voltage regulator chip connected across the transformer is stable and does not oscillate. In a simple battery charging circuit, the battery is directly connected across the output capacitor of the voltage regulator chip. In most cases additional filter capacitors are not required in such circuits.
What is a capacitor filter circuit?
The capacitor filter circuit is applicable for small load currents. The main function of half wave rectifier is to change the AC (Alternating Current) into DC (Direct Current). However, the acquired output DC is not pure and it is an exciting DC. This DC is not constant and varies with time.
How to design a battery charging circuit with or without filter capacitor?
The design of a battery charging circuit with or without filter capacitor depends on many factors including the type of battery and the charging method used. One must follow the safety precautions and have basic knowledge about the batteries being charged. The most common battery charger circuit is the constant-voltage battery charger.
Do battery chargers need a capacitor?
Some chargers do not deliver pure DC and instead supply a pulsating (uneven) DC voltage. In such cases an output capacitor can be added across the circuit to smoothen the pulses. In most of the common lead-acid battery charger circuits, capacitors are not required across the output terminals.
Do you need a capacitor to charge a lithium ion battery?
In such cases an output capacitor can be added across the circuit to smoothen the pulses. In most of the common lead-acid battery charger circuits, capacitors are not required across the output terminals. However, charging a lithium-ion battery is slightly different and requires additional circuitry and a capacitor to protect the battery.
