When we think about laptop batteries, many of us consider the rechargeable ones that we deploy nowadays. Still, a few decades ago AA batteries were widely deployed in laptops. It took many AA batteries to run a laptop. Moreover, it could not run for long. Some laptop users remember the heavy-weight lead acid based batteries that did not only last long, but also made a laptop exceedingly heavy. Since then the manufacture of laptop batteries has altered. Lighter nickel cadmium batteries (NiCd) substituted lead acid based ones. Still, these batteries were not deployed long, because nickel metal hydride batteries (also known as NiMH) were introduced. They lasted a lot longer and were lighter. Their main drawback was the so-called memory defect they had. If the battery had not discharged completely, it remembered it and put out less power than it should do. When lithium ion batteries (LiON) appeared on the IT market, customers witnessed a tremendous progress in laptop batteries production. These batteries are much lighter than other laptop batteries and have not got any memory defect. They are used in technically advanced models. Even though LiON batteries run for several hours non-stop, they need re-charging. As more and more people purchase laptops every year, the demand for longer lasting batteries is ever raising. There will surely be innovations until laptop batteries that do not require to be re-charged are made. No matter what you deploy your laptop for, you know that you require a long-lasting battery.
