Batteries are either primary or secondary. Primary batteries can be used only once because the chemical reactions that supply the electrical current are irreversible. Secondary (or storage) batteries can be used, charged, and reused.
Give examples of primary and secondary cells. Examples of primary batteries include dry cells and alkaline batteries while lead acid batteries, nickel-cadmium batteries are examples of secondary batteries. Batteries can be broadly divided into two major types. Primary Cell / Primary battery & Secondary Cell / Secondary battery.
The key points are: - Primary cells cannot be recharged while secondary cells can be recharged by passing current in the opposite direction. - Dry cells are inexpensive but have a limited shelf life. Lead-acid batteries are rechargeable and commonly used in vehicles. Nickel-cadmium batteries can be recharged hundreds of times.
Secondary battery chemistries, distinct from primary batteries, are rechargeable systems where the electrochemical reactions are reversible. Unlike primary batteries that are typically single-use, secondary batteries, such as lithium-ion and nickel-metal hydride, allow for repeated charging and discharging cycles.
Primary batteries are “dry cells”. They are called as such because they contain little to no liquid electrolyte. Again, these batteries cannot be recharged, thus they are often referred to as “one-cycle” batteries.
Secondary rechargeable batteries can be drained and recharged several times with an applied electric current, reverse current can be used to restore the original composition of the electrodes. Lead acid batteries used in automobiles and lithium ion batteries used in portable gadgets such as laptops and mobile phones are two examples.
Secondary Cell: A secondary cell, also known as a storage cell, generates electrical current through a chemical reaction and can be recharged after being discharged. Examples include lead-acid cells, nickel-cadmium alkaline cells, etc. What are the Differences Between Cell and Battery? A cell is an individual unit.
Batteries are either primary or secondary. Primary batteries can be used only once because the chemical reactions that supply the electrical current are irreversible. Secondary (or storage) batteries can be used, charged, and reused.

Primary cell battery; Secondary cell battery; Primary and Secondary cell battery 1. Primary Cell Battery. Primary cell batteries are designed to be used for once, and discharged. We cannot recharge this type of batteries. Some example of primary cell batteries are.
N 2 = number of turns on the secondary, V 1 = primary voltage, V 2 = secondary voltage, I 1 = primary current, I 2 = secondary current. Example: A 50 kVA single-phase transformer has a 4000 V primary, and a 400 V secondary. Assuming an ideal transformer, determine (a) the primary and secondary full-load currents, (b) the transformer turns ratio.
