The nickel-cadmium battery, known as nickel-cadmium (pronounced "quasi-Kad"), which used to be the most common type of laptop battery. Nickel cadmium batteries could not hold on to power largely by today's standards, and could only be charged with a limited number of times. nickel-cadmium batteries can be easily ruined by staying in the charger after it has reached full charge, or to be recharged before they were completely dead. The latter problem, called the "memory effect" means that if you recharge the laptop before it was completely down, would remember the moment you put it back in the charger, and now downloads only the next time you use it.
The nickel metal hydride (NiMH) laptop battery was the next step after NC. NiMH batteries can have much more energy than NiCd, but still had some memory effect - though not as pronounced. Lithium ion (Li-Ion) is the latest technology of laptop batteries, although Li-Ion batteries have approximately the same amount of power as NiMH batteries, which are considerably lighter and much higher. Laptop Battery Li-Ion has no memory effect and lasts much longer than their predecessors. If your laptop supports multiple types of batteries, and Li-Ion battery is one of them, then you should choose the Li-Ion as the best type of battery for your laptop.
