Difference between the alkaline battery and lead acid battery

The main difference between alkaline and lead acid batteries is that lead acid batteries can be recharged while alkaline batteries are non-rechargeable.
A battery usually has one or sometimes more electrochemical cells. It also has some external connections that can be connected to help different power devices like flashlights and smartphones. The batteries also have negative and positive terminals. This is the anode and the cathode, respectively. Alkaline and lead acid batteries are the types of batteries available in the market today.

Lead acid battery
This battery still finds wide usage, and it was the first rechargeable battery introduced into the market. The energy-to-weight ratio and the energy-to-volume ratio of these batteries are rather low. The battery can supply a high surge current. This makes it have a large ratio in terms of power to weight. The batteries are quite affordable.

The differences between alkaline and lead acid batteries
When fully charged, lead acid batteries have a negative lead plate and a lead oxide positive plate. Sulfuric acid is used as the electrolyte. This is where the chemical energy is stored. When overcharging or charging, hydrogen and oxygen are produced caused by water electrolysis.

When the battery discharges, the hydrogen ions will form in the anode and move in the electrolyte solution. They are then consumed by the positive plate. The consumption of H2SO4 occurs on either plate. In the charging process, the reverse happens.

Alkaline battery
This is a primary battery where energy generation happens when manganese oxide and zinc metal react. The reason why the battery is called alkaline can be attributed to the potassium hydroxide, an alkaline electrolyte. Some of the batteries under this category may be recharged. However, attempting to recharge this type of battery can cause a rupture.

The negative electrode in an alkaline battery is zinc metal. Manganese oxide serves as the positive electrode. As noted, there is an alkaline electrolyte that is not a part of the reaction. The electrolyte is unchanged because the hydroxide ions are formed and consumed equally when discharging. The chemical energy in an alkaline battery is usually stored in zinc metal.

Lead acid batteries can be used in applications such as heavy trucks, forklifts, motorcycles, and electric bicycles. They can also offer backup power for alarms, such as on computer systems or UPSs.

Alkaline is very common, but they are being phased out with the entry of rechargeable battery options. However, they are still widely used. The batteries are used in different applications like fans, mp3 players, radios, and remote controls. This is because of their high run time and the fact that they last long.
