Compare and contrast a traditional battery and a maintenance-free battery.
What will be an ideal response?
Both a traditional lead-acid battery and a maintenance-free battery contain two groups of coated lead plates, known as electrodes. The electrodes are immersed in a dilute solution of electrolyte. One group of plates forms the positive electrode, whereas the other forms the negative electrode. Glass, rubber, or other insulating materials are used as separators to keep these electrodes from making contact.The traditional battery has a vent and vent cap for each cell. These devices permit gases to leave the cell while charging and the addition of distilled water that is lost by evaporation and during charging. This maintenance-free battery, however, does not require the periodic addition of water to the electrolyte solution because it has an electrolyte reservoir. The maintenance-free battery may be purchased with terminals located on the top or side to satisfy a variety of installation requirements.
