The first batteries used in laptops were AA batteries. Many of them were needed, and they did not last very long. From AA batteries, laptops moved up to featuring heavy lead-acid-based batteries; these were heavy and also had a short daily life. The first type of rechargeable battery were nickel-cadmium batteries, or NiCAD; although they were inexpensive and had high output, they were heavy and not as efficient as the industry wanted them to be.
