The measured terminal voltage of any battery will vary as it is charged and discharged (see Figure 1). The MPV (mid-point voltage) is the nominal voltage of the cell during charge or dis-charge.
The maximum current that a battery can deliver is directly dependent on the internal equivalent series resistance (ESR) of the battery. The current flowing out of the battery must pass through the ESR, which will reduce the battery terminal voltage by an amount equal to the ESR multiplied times the load current (V = I X R). X R).
constant-voltage charger is a circuit that recharges a battery by sourcing only enough current to force the battery voltage to a fixed value. constant-current charger is a circuit that charges a battery by sourcing a fixed current into the battery, regardless of battery voltage.

The voltage calculated from equilibrium conditions is typically known as the nominal battery voltage. In practice, the nominal battery voltage cannot be readily measured, but for practical battery systems (in which the overvoltages and non-ideal effects are low) the open circuit voltage is a good approximation to the nominal battery voltage.
For example, in lead acid batteries, each cell has a voltage of about 2V. Six cells are connected to form a typical 12V lead acid battery. Due to the polarization effects, the battery voltage under current flow may differ substantially from the equilibrium or open circuit voltage.
The voltage provided to power the load is obviously very important: The Ni-Cd and Ni-MH batteries have a 1.25V nominal cell voltage (their discharge voltages are gener-ally assumed to be identical).
