Lenovo ThinkPad X121E Battery
Your Lenovo ThinkPad X121E battery makes your laptop portable so as to work or play anywhere in the house or even outdoors! The larger the battery, the longer it will last on a single charge. Buying a battery with a higher milliamp rating is fine, it just means the battery will go further on a single charge. What really is critical to a battery fitting your laptop is the physical size of the battery as well as the connection. 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 old one.
Subtle hints the li-ion battery will not live much longer
- The battery gets puffy and looks like it will explode
- The laptop lasts less than half an hour before it shuts itself down
- The Lenovo laptop refuses to turn on while not connected to the AC adapter
