We all know that our vehicle's batteries should be changed, just like the ones in a TV remote. But why is that? Do they have an expiration date? The answer is yes and no - while they have a recommended use period, they can be changed prematurely due to problems of fast aging. The Chemistry Behind Batteries Before we get into the nitty-gritty of battery aging, let's briefly explore how batteries work. At their core, batteries are chemical devices that store and release electrical energy. They consist of two electrodes (usually one made of a metal oxide and the other of a metal) submerged in an electrolyte solution. When you use a battery-powered device, a chemical reaction occurs between the electrodes and the electrolyte, generating electrical energy. Over time, as this reaction repeats, it can lead to some interesting changes within the ... read more
