Primary Battery vs Secondary Battery | Difference between Primary Battery and Secondary Battery
This page compares Primary Battery vs Secondary Battery and mentions difference between Primary Battery and Secondary Battery.
The figure-1 depicts dry cell and wet cell types. Dry cells are primary cells or batteries. Wet cells can be used as primary cells (i.e. non-rechargeable) or secondary cells (i.e. rechargeable). Let us summarize difference between Primary Cells and Secondary Cells.
| Specifications | Primary Battery | Secondary Battery |
|---|---|---|
| Recharging | These batteries can not be recharged or reused. | These batteries can be recharged or reused. |
| Reaction | Irreversible reactions occur | Reversible reactions occur |
| Number of times it can be used. | only once, can be used as long as active materials are present. | more than once by recharging |
| Application | It is used in portable devices, watches, transistors, radios etc. | It is used in automobiles, digital cameras, laptops, flash lights, electronic equipments etc. |
| Self discharge rates | Lower | Higher |
| Initial cost | Lower | Higher |
| Life Cycle cost | Higher | Lower |
| Disposable, can not be recharged. | Regular maintenance needed, Periodic recharging required. | |
| Examples | Leclanche cell, Dry cell, lithium cell | Lead storage battery, Ni-Cd battery, Lithium Ion Cell |
