Lenovo S21E-20 Battery
Your Lenovo S21E-20 battery makes your laptop portable so as to work or play wherever you fancy. Getting a battery with a higher amp rating is OK, because it simply implies that the battery will last longer. What is truly important is the connection type and physical size of the battery. The more power the battery has, the longer you will be able to use the laptop when fully charged. Not all batteries are the same, make sure and double-check the size and model number in order to make sure it is similar to the one you are going to replace.
Important signs your battery should need replacing
- The laptop does not last longer than 45 minutes while unplugged
- The laptop is unable to boot up while not connected to the AC adapter
- The battery gets puffy and looking like it is going to burst
