You decided to look into a new battery when having some trouble with your laptop, such as you can’t have the computer charging, or else it dies instantly. Or your laptop battery has broke but you are not willing to buy a new genuine one. It is a good choice to purchase a replacement battery.
Then the problem came as this is your first time to replace the battery: How to Choose a Compatible Replacement Laptop Battery?!
Uh uh uh, let me have a think!
Well, the choise of a laptop replacement battery is determined primarily by a few basis and they include: Part number; Brand, and Model; and finally the Voltage.
Part Number
Essential to the purchase of your new laptop battery is the part number. A part number is a unique identifier that is assigned to a part to simplify referencing and to unambiguously define a part within a single manufacturer. The part number above all is what needs to be known before going to buy your battery.
It can be found on the battery itself.
Brand, and Model
Secondly the brand and model are next most important part identifiers you must know.
The brand is the manufacturer (e.g. Sony, Fujitsu, Dell). The model is a multi-component word that includes the line and actually model number. For example the Sony VAIO VGN-FZ90S is an example of a sony made laptop that is part of the VAIO series and which has model number VGN-FZ90S.
Most laptop’s hold this information within your computer’s system info. To access this info go into the properties of your computer and view the model information.
Voltage
For laptop batteries the most common voltage measurements are: 7.2V, 9.6V, 10.8V, 11.1V, and 14.4V. Please chose the closest voltage to your original battery.
Remember nominal voltage allows for slight deviation from the original but you cannot use a 7.2V battery if it requires 14.4V.
The best example would be a 10.8V battery could be used with an 11.1V battery.
