Battery Discharge and its relation to the application
A 100-amp hour battery supplies a current of 5 amps for 20 hours, during which time the battery''s voltage remains above 1.75 volts per cell (10.5 volts for a 12-volt battery). If the same battery is discharged at 100 amps, the battery will only run for approximately 45 minutes before the voltage drops to 1.75 volts per cell, delivering only 75-amp hours of total power.

View more6 FAQs about [Internal current direction when the battery is discharging]
What is the direction of current flow in a battery circuit?
The direction of current flow in a battery circuit refers to the movement of electric charge, traditionally considered to flow from the positive terminal to the negative terminal. According to the National Institute of Standards and Technology (NIST), current is defined as the flow of electric charge, typically carried by electrons in a circuit.
Does the current flow backwards inside a battery?
During the discharge of a battery, the current in the circuit flows from the positive to the negative electrode. According to Ohm’s law, this means that the current is proportional to the electric field, which says that current flows from a positive to negative electric potential.
What happens when a battery is discharged?
During the discharge of a battery, the current in the circuit flows from the positive to the negative electrode. According to Ohm’s law, this means that the current is proportional to the electric field, which says that current flows from a positive to negative electric potential. But what happens inside the battery?
What are some common misconceptions about battery flow directions?
The common misconceptions about battery flow directions primarily involve the movement of current and electrons. Many people mistakenly believe that current flows from the positive to the negative terminal, but this is not entirely accurate. Current flows from positive to negative. Electrons flow from negative to positive.
How does a battery charge and discharge?
Charging and Discharging Processes: Current flow reverses during the charging process. A battery is recharged by applying external voltage, prompting the current to flow in the opposite direction. This process restores the original chemical compositions at the electrodes, allowing the battery to be used again.
Why does a battery Flow in the opposite direction?
This means that while electrons move from the negative terminal to the positive terminal inside the battery, the applied current is considered to flow in the opposite direction. This statement is incorrect.
