Lenovo ThinkPad 4300 Battery
Your Lenovo ThinkPad 4300 battery allows you to move freely about so that you can use it where you want. Because no battery is the same, make sure and double-check the model number and compare it to the one you are going to replace. More amps in a battery basically means the longer it will last on one charge. It is OK to buy a battery with more milliamps, because it simply implies that the battery will last longer. What really is critical to a battery fitting your laptop is the physical size of the battery as well as the connection.
What are the clues to watch out for to know my battery has gone bad?
- The battery has its case swollen and looks like it will explode
- The Lenovo laptop refuses to turn on when not connected to the charger
- The laptop lasts under 20 minutes while using the battery only
