Dry Cell vs. Wet Cell: Key Differences Explained

battery dry cell wet cell electrolyte power source

This article breaks down the key differences between dry cells and wet cells, two types of electrochemical cells used to provide power.

Introduction:

  • Dry Cell: An electrochemical cell using an electrolyte with low moisture content. This design minimizes leakage, making dry cells ideal for portable devices.
  • Wet Cell: An electrochemical cell containing a liquid electrolyte. Wet cells are commonly used in vehicles like cars and motorcycles as a power source.
