Laptop Batteries Types and Styles

Find laptop batteries information and resources

Several types of laptop batteries have evolved over the years. The first rechargeable batteries were the Nickel Cadmium Batteries (NiCd). The next step in battery evolution was the Nickel Metal Hydride Batteries, or NiHM. Both types of batteries are no longer in popular use due to a memory effect that required the notebook computer battery to be fully discharged before recharging for optimal output. The notebook battery currently in use is the Lithium-ion, or Li-ion type. This lap top battery is popular because of its lighter weight, rapid charging ability and environmental friendliness.

Older laptops may still have an old NiHM battery that can be upgraded to Li-ion. There are also smart batteries available that better manage battery energy and usage over time. The following resources will help you learn about different laptop batteries types and styles:

1. Find out what you need to know about older NiHM laptop batteries.
2. Read about the newest industry standard Li-ion laptop batteries.
3. Learn more about the power-saving features of the smart lap top computer battery.
   

 

Learn how NiHM laptop batteries work, and how to find out if you can upgrade

You may have an older laptop that still uses a NiHM battery. If an Li-ion battery option is available for your laptop, it's usually a smart idea to take it. Li-ion batteries are lighter, and handle their charge better. Usually you can look up the model of your laptop on the manufacturer website to find out whether they have a newer Lithium-ion battery option. If you're stuck using NiHM laptop batteries, it's a good idea to know how they work and how best to care of them.

Lithium-ion laptop batteries are lightweight and handle their charge better than the older NiHM or NiCd batteries. They only lose roughly 5 percent charge monthly, compared to around 30 percent in NiHM batteries. They can also handle more charge and discharge cycles than the older batteries.

Most smart battery technology is based on the SBS or Smart Battery System, an industry-standard for rechargeable battery technology. Smart laptop batteries report their own state, and are capable of self-calibration, vastly extending the life of the battery. This functionality is enabled by internal microprocessor circuits.
