When choosing a laptop battery replacement, meeting the manufacturer's specifications is important to prevent damage to your laptop. Information you may need when purchasing a laptop battery replacement includes:
Part Number, Make, and Model
The three most important identifiers when buying a laptop battery replacement are the part number, make, and model of your existing battery. For example, if you own a Dell XPS 13, the make identifies the manufacturer, which is Dell, while the model would be XPS 13. To determine the part number of your battery, simply shut your laptop down, unplug the power cord, and open the battery compartment. The information will be printed directly on the battery
Voltage, Shape, and Size
Double-check your existing computer battery to ensure you're purchasing a replacement that matches its voltage, shape, and size. If your original battery is rated at 14.4V, try to match that capacity when selecting a replacement.
