In Previous post on Laptop Buyer’s Guide – Processor I provided some information on various processor to buy laptop.
Here is little bit information of Battery
There are three different laptop battery chemistries. Nickel cadmium was the first chemistry, which was followed in time by nickel metal hydride and lithium ion battery types. Notebook batteries are also sometimes referred to as “smart” or “dumb.” These terms are explained below.

Nickel Cadmium (NiCd) NiCd batteries were the first rechargeable batteries for notebook computers and featured low cost, versatility and high output current capability. NiCd batteries can be charged rapidly and used in a wide range of products. However, they are now being designed out of notebooks in favor of the newer and higher power NiMH and LiON batteries.
Nickel Metal Hydride (NiMH) NiMH batteries represented a significant improvement over NiCd batteries due to improvements in cost, safety, reliability and capacity. Currently the most widely used notebook battery, the NiMH battery has only one drawback. The “memory effect” of NiMH batteries requires that they be fully discharged prior to recharging for maximum charge effectiveness.
Lithium Ion (LiON) LiON batteries are now the most popular notebook battery because of improvements over NiMH in the area of memory effect. In addition, for batteries of comparable capacity, LiON batteries are generally somewhat lighter in weight than NiMH batteries. Because the LiON chemistry is the newest in the market and offers these benefits, the market price for LiON batteries is often significantly higher than for NiMH batteries with the same actual capacity.
Smart / Dumb Batteries Some batteries are denominated as “smart” or “dumb.” Smart batteries have internal microprocessor circuits which help manage battery energy, report the state of the charge, predict running time and track battery usage. Dumb batteries are counterparts of smart batteries but do not have these smart battery features.
