Customer ServiceAs noted before, a 12-V truck battery is physically larger, contains more charge and energy, and can deliver a larger current than a 12-V motorcycle battery. Both are lead-acid batteries with identical emf, but, because of its size, the truck battery has a smaller internal resistance (r). Internal resistance is the inherent resistance to the flow of current within the source itself.

Customer ServiceWhen connected to an external load, a redox reaction within the battery converts high-energy reactants into lower-energy products. This releases the energy difference to the external circuit as electrical energy. Initially, “battery” referred to a device of multiple cells.
An electric battery is an energy storage device comprising one or more electrochemical cells. These cells have external connections used to power electrical devices. When providing power, the battery’s positive terminal serves as the cathode, while the negative terminal functions as the anode.
“The ions transport current through the electrolyte while the electrons flow in the external circuit, and that’s what generates an electric current.” If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes).
It is helpful to think of circuits in terms of energy. Charges move along the circuit and their potential energy changes as they go through components, while it remains constant as they move through a wire. If a positive charges enters the negative terminal of a battery and exits the positive terminal, its potential energy will have increased.
Electric battery construction involves several key components that work together to store and deliver electrical energy. Anode (Negative Electrode): The anode is where the oxidation reaction occurs during discharge, releasing electrons into the external circuit. Common anode materials include graphite and lithium compounds in lithium-ion batteries.
The flow of electrons is reversed by providing electrical energy to the battery, driving the reduction reaction at the anode and oxidation at the cathode. This replenishes the chemical potential in the battery, storing energy. Notably, this process applies to rechargeable batteries like lead-acid and lithium-ion batteries. 3.
