AI Customer ServiceWith the move from analog to digital, new demands are placed on the battery. Unlike analog portable devices that draw a steady current, the digital equipment loads the
AI Customer ServiceThis represents a large current from a relatively small battery of about 800 milliampere (mAh) hours. A current pulse of 2.4 amperes from an 800 mAh battery, for example, correspond to a C-rate of 3C. This is three times
AI Customer ServiceWhen battery is fully charged, it can supply high current while maintaining voltage across it, hence low internal resistance. In an electrolytic cell, the conduction of electric current is mainly due to the presence of the ions in the electrolyte. When the battery is fully charged, the concentration of ions is maximum.
Voltage: As the resistance of what we have connected to the battery is fixed, the higher voltage we have, the more current we can provide. Or put another way, the voltage will determine the current intensity and the higher the voltage, the more intensity we will give. - If a battery is discharged, it will give less intensity of current.
Internal Resistance depends on the ability of the battery to supply current. A discharged battery cannot simply supply current. When high current/low resistance is attached across it, voltage drops across the terminals. When battery is fully charged, it can supply high current while maintaining voltage across it, hence low internal resistance.
The more capacity (Ah) a battery has, the more electricity it can provide. In theory, a battery that has 100Ah could give a current intensity of 100 Amps for 1 hour, an intensity of 1 Ampere for 100 hours, or 2 Amps for 50 hours. However, this is not always the case, as the faster a battery discharges, the more power it loses.
If a battery is discharged, it will give less intensity of current. - If we increase the voltage, the current intensity will automatically increase. In a car, everything that is connected to the battery is prepared to operate at a voltage of 12V. What would happen, therefore, if we could connect a 24V battery or 2 12V batteries in series?
So twice the power for half the time is the same amount of energy drained from your battery. EDIT: If the question is why would the battery capacity decrease over the expected ideal, then Brian's comment is the answer. The internal battery impedance means more power dissipation at higher currents.
