When your battery suddenly run out of charge and can not be fully charged, it means your need to buy a replacement battery.
There are so many battery manufacturers for you to choose from. I suggest you choose a company which provide high quality batteries, I suggest you choose a company which batteries are certified by CE and RoHS with a 1 Year Warranty. As battery is a consumable product.
Now, let’s talk about your biggest concern: how to select a compatible battery, check the model number of your laptop’s original battery, if you have no idea about this, just shut down the laptop and unplugged, carefully check the inside, you should find P/N along with some numbers on the battery, part number also can be found on the box of battery. If you still not sure which one, you may consult the customer service of battery store for help. It’s really a waste of time and money if your choose a wrong one.
