If you live laptop batteries like we do, then you can reel off a ton of details about the unsung heroes of the mobile computing revolution. We’re so into this stuff that many of our family members have had to beg us to stop talking laptop batteries and the wonders of a PA2487U, an 02K7054, or an F1705A.
Some of you, however, need a basic primer on just what a laptop computer battery is. Well, this article is just for you. Let’s start off with the most fundamental question: what is a laptop computer battery?
A laptop battery provides a source of electrical energy that supplies needed power to your laptop. The laptop battery uses a combination of cells that are electrochemically active, which is to say, they naturally transmit electrons from one end of the laptop battery (or “terminal”) to the other, when those two ends are connected in a circuit. A laptop computer battery can be engineered to be highly portable, like a watch battery, or it can be built to withstand extremes in operating conditions, like a car battery.
Engineers build laptop batteries by employing various “electrochemical cocktails” that create the desired flow of electrons under the conditions that are specific to whatever application they’re working on. A laptop battery, for instance, needs more power than a watch but needs to weigh less than a car battery. Other relevant characteristics of a laptop battery include its manufactured cost, its environmental impact, its expected useful life, and its chemical volatility.
One of the main distinctions among all laptop battery technologies is whether it can be used more than once. In laptop computer battery industry lingo, “primary” laptop batteries are those that can be used only once, while “secondary” laptop batteries can be recharged are reused multiple times.
The laptop battery falls into a secondary category of battery technology, which includes Lithium-Ion batteries. This technology is actively used in all of today’s laptop batteries as well as older technologies like Nickel-Cadmium, Nickel Metal Hydride, and Lead Acid (which is what’s used in car batteries).
