What is battery discharge tester ?
A battery converts chemical energy into electrical energy by creating a potential difference between two electrodes (anode and cathode) through a chemical reaction.
When a battery is discharged, electrons flow from the anode to the cathode while ions in the electrolyte move to maintain charge balance; when it is charged, the process is reversed.
