Current flow in batteries?
$begingroup$ Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics. Not noticable at most voltages, but see what happens when you touch a peice of metal to a 100,000kV line, even in a vaccumm with no earth, a sizeable current will flow to bring the metal to the same electrostatic charge.
current source
At 3.7 V, that would be 16 A. And, the current goes up as the battery voltage runs down. Check the datasheet of your battery. That''s either past the reasonable limit, or high enough that you will get significantly reduced energy per charge, and probably reduced lifetime. Pop up a couple of levels and think about the larger problem.
batteries
Le''s assume the load resistance is 4.5ohm and battery voltage is 9v, so current flow through the loop is 2amp; for the same load resistance(not be changed in any variation of voltage and current), if the battery voltage is 18v the current flow through the loop becomes 18v/4.5ohm=4amp. if I am wrong please give me feed back.

ELI5: How do battery charge level indicators work?
They measure the voltage of the battery. If for example The battery is declared to have a voltage of 1.5V (e.g. AA battery), the actual real life voltage varies between 1.5+ and 1.3V for example. The lower the voltage, the less energy is left in the battery. This is how to measure a battery when it is not supplying any current/energy to a load.
voltage
$begingroup$ The charge voltage depends on the battery chemistry. Some lithium ion batteries are charged to 4.2v, some to 3.6v, etc. And the battery voltage will vary with the current charge state - less charge means less cell voltage, but the relationship is not linear (quick drop from completely full, flatter plateau for a while, quick drop again when getting low).

6 FAQs about [How does the battery display the current ]
Why is current the same on both sides of a battery?
In a battery, current is the same on both sides because it forms a closed circuit. The battery’s internal chemical energy converts to electrical energy, generating a voltage difference between terminals. This voltage difference drives current through the circuit, from one terminal to another, and back through the battery.
Can a current flow in a battery?
Maybe something like "Current flow in batteries?" Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics.
What happens when a battery is connected to a circuit?
When a battery is connected to a circuit, the electrons from the anode travel through the circuit toward the cathode in a direct circuit. The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current.
How does a battery circuit work?
The simplest complete circuit is a piece of wire from one end of a battery to the other. An electric current can flow in the wire from one end of the battery to the other, but nothing useful happens. The wire just gets very hot and the battery loses stored internal energy – it ‘goes flat’ and stops working.
How does a battery produce electricity?
“The ions transport current through the electrolyte while the electrons flow in the external circuit, and that’s what generates an electric current.” If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes).
How does voltage affect a battery?
This voltage difference drives current through the circuit, from one terminal to another, and back through the battery. As the current flows, the same amount of charge passes through both sides of the battery, ensuring equal current on both sides.
