Why Would You Buy a New ThinkPad Battery?

Your laptop comes with a battery unit when you buy it. Of all the laptop hardware, it is the battery that has the shortest lifespan. You will be required to replace after some time of continuous use. So, the first reason to look for a ThinkPad battery is to replace the faulty one inside your computer.

Another reason for looking for a new 6-cell or 8-cell ThinkPad battery is to have a spare when you have your system in the field. If you cannot access electricity when the battery requires recharging, then you can buy an extra pair to use when the first one drains out. It is a way of ensuring that your system is continuously running, even when you are in the field.

Can you Buy a ThinkPad Battery Anywhere?

You have to be keen when shopping for laptop batteries. They are some of the expensive hardware on your computer, and you can easily fall for a fake one if you want to save on the cost. The best place to buy any new battery, no mater if it is a 3-cell a 4-cell ThinkPad battery, or any other type, is from the manufacturer or certified distributor.

Apart from buying fake batteries that will not deliver the promised power, it can damage your system if it produces more than the rated voltage for your system. That will, in turn, cost you more to repair your computer that might die forever. As our advice, always look for a reputable seller and buy the best battery for your ThinkPad laptop.

How Do You Extend the Battery Life?

The service life of a ThinkPad battery varies from one user to the other. The difference is made by how you manage your batteries. The first option is to never let your laptop battery drain to zero. Recharge it when it is at least 10 percent full to preserve cells. Also, when you have to keep your laptop for a long time, when fully charged, take the battery out of the computer.
