Can I upgrade my laptop battery to a newer chemistry?

A question recently asked was, "Can I upgrade my Laptop Battery to a

newer chemistry?"

If the laptop has been pre-configured by the manufacturer to accept

more than one type of rechargeable battery, then the answer is yes.

The different types of batteries requires a different charging patterns

to be properly recharged and used in the laptop. Always refer to your

laptop computer manual or contact your manufacturer to find out which

battery types can be used in your laptop.

Nickel Cadmium (NiCad,NiCd), Nickel Metal Hydride (NiMH) and Lithium

Ion (LiIon, Li-Ion) are the three major types. Due to health and safety

and inefficencies, Nickel Cadmium and Nickel Metal Hydride batteries

are either discontinued or in the process of being discontinued.

Lithium Ion is relatively new and popular type. There is an even newer

type, Litium Polymer Ion or Lithium Polymer. This is much more

efficient and offers better power to weight ratio.
