Lenovo ThinkPad T440 Battery
Your Lenovo ThinkPad T440 battery makes your laptop portable so as to work or play anywhere you please. Buying a battery with a higher milliamp rating is fine, because it simply implies that the battery will last longer. What is truly important is the connection type and physical size of the battery. More amps in a battery basically means the longer you will be able to use the laptop on a single charge. Because no battery is the same, be sure to check the model number and compare it to the one you are going to replace.
What are the clues to watch out for to know my primary battery is on its last leg?
- The laptop does not last longer than 45 minutes before it shuts itself down
- The laptop battery is puffed up and looking like it is going to burst
- The laptop does not turn on when it is unplugged
