There are lots of manufacturers that make laptops with various configurations. Laptop power requirements vary based on the design, specifications, and configuration of specific models.
Based on an assessment of the maximum power requirements and space available for battery installation, laptop manufacturers order batteries that are suitable for their various laptop models. Laptop manufacturers usually do not make their batteries, but rather supply them from specialist battery manufacturers.

All modern laptops have a lightweight lithium-ion or lithium-polymer battery that is usually built into the laptop. The battery is strong enough to work with a laptop and all accessories like MP3 players, DVD players, and USB devices.
With normal use, lithium-ion batteries are expected to last about three years. However, it is important to note that the three-year period begins immediately after the battery is manufactured and not when it is used. The indication that the battery needs to be replaced usually appears when the laptop becomes inoperable unless it is connected to a power source via an adopter.
If it is clear that the battery needs to be replaced, it is advisable to contact an authorized retailer for that particular brand of laptop. An authorized dealer can provide the correct backup battery type and install a spare battery upon request.
