五. Type of battery:

Lithium-ion Battery:

If you are using a laptop with a Lithium-ion battery (most newer laptops), it should give you

between 300-500 charge/discharge cycles. This type of battery doesn't like full discharges and

should be avoided when-ever possible. The technology is still being enhanced and should

continue to be the battery of choice for laptop manufactures in the future. Elevated

temperatures seem to have an adverse effect on this batteries life. Lithium-ion battery

manufactures believe that a typical life span should be somewhere between 2 to 3 years. Most

lithium-ion batteries fail because of exposure to excessive heat rather than the charge/discharge

habits of the user.

Nickel-based Battery:

(nickel cadmium and nickel metal hydride) Unlike the lithium based battery, this battery likes

being discharged and then fully charged. If a Nickel-based battery is always partially discharged

before recharging, the usable capacity of the battery will be reduced. This battery has a voltage

capacity 3 times less than the Lithium battery (1.2 V -vs- 3.6 V) making it less commonly used

in the portable industry. If your laptop is 3 or more years old, then most likely you have this

type of battery.
