Laptops yield more power than smartphones, and they have more portability as compared to regular desktop personal computers, so in that case, it needs a stronger battery. You should keep in mind that high capacity batteries are sometimes not right for you. The high capacity batteries have higher weight than the regular batteries. For example, carrying them with your luggage at airports might become an issue. But these batteries make the laptops last longer than their usual timings so high capacity batteries are more useful that way. When your battery is working at an abnormal rate, it can also affect the performance of your computer.
The following points are useful when you are buying an ultrabook battery:
1. Being aware of your laptop Brand and its Model: Knowing whether your laptop is Dell or Vaio does not matter. You should know the precise model number of your laptop when buying an ultra–book battery as it significantly reduces the times it takes to find the replacement battery.
The model number can either be printed on the right side of the laptop or beneath the base. It could be printed inside the battery compartment if you are unable to find it near the spots mentioned above. If you have to check the model number inside the battery compartment, be sure to unplug and turn off your computer first, for safety measures.
2. Know your battery model number: If you cannot find the model number via the processes mentioned above, then you can surely find a model number on the battery itself. Knowing the battery model can be the quickest way to find a replacement battery for your computer. One of the fastest ways to find a battery is an online web search. There are several useful websites to find online. You have to insert the model number in the search bar of any site that seems trustable to you. (For example Batteries.com)
3. Make sure to verify a battery before you buy: Before purchasing the battery, you should take precise measures and check its warranty. For example, you should scrutinize the battery connector and compare it to the connector of your old battery (connectors are present on either side of a battery). If they both do not match, then the new battery will not connect to your laptop. In case you do not have the older battery, you can always compare the connector of a new battery with the battery compartment plug of your computer.
4. Make sure to check the back of your laptop. When inspecting your laptop before or after buying the battery, make sure to inspect the battery connector (labelled battery connector). It may be that the new battery you have just purchased or looking forward to buying does not look like the former or has a different shape or does not seem like it would fit in your laptop’s battery compartment area. Then you should contact the website’s call centre and ask for their verification if the battery is correct for your computer or not.
