Why does a battery drop when a current is drawn?
When a current is being drawn from the battery, the sudden drop is due to the internal resistance of the cell, the formation of more sulphate, and the abstracting of the acid from the electrolyte which fills the pores of the plate. The density of this acid is high just before the discharge is begun.
What happens when a battery is discharged?
This voltage drops suddenly when the external load is connected and current is driven out from the battery. The voltage drop at the beginning of the discharge may cause, under circumstances such as heavy work or high rate discharge, the battery to exceed the minimum voltage required by the external load.
Why does a lead-acid storage battery lose its capacity?
Lead-acid storage battery will lose part of its capacity due to self-discharge. Therefore, before lead-acid battery is installed and put into use, the remaining capacity of the battery should be judged according to the battery's open circuit voltage, and then different methods should be used for supplementary charge for the battery.
What voltage does a lead-acid battery run?
The battery block that supplies current to these systems is usually sized according to the minimum required voltage of the external load and the ohmic voltage drop along the electrical line. Although currently rated at 2 V/e for sizing purposes, lead–acid batteries operate at a starting voltage of 2.1 V/e when fully charged.
What contributes to the voltage drop in a lead–acid cell?
The different contributions to the voltage drop in the lead–acid cell can be grouped in three main groups: those affecting the electrolyte resistance, those related to the material structure, electrodes and separators, and those involved in the electrochemical reactions at the double layer.
