Why do batteries run down?

Answer 1

The electrolyte in batteries is partially depleted as the reaction proceeds, and as soon as the reaction ceases, the battery's power-generating mechanisms also come to an end. Batteries contain electrodes dipped into an electrolyte, which causes spontaneous redox reactions. The Gibb's energy of these reactions is converted into electrical work and used from suitable purposes.

A good battery can withstand many charging and discharging cycles. Primary cells, like the dry cell or the mercury cell, cannot be reused. However, secondary cells, like the lead accumulator or the nickel-cadmium battery, can be recharged and used repeatedly.

Answer 2

Batteries run down due to chemical reactions occurring within them, leading to a depletion of the materials involved in generating electrical energy.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
