Lenovo ThinkPad 4289 Battery
Your Lenovo ThinkPad 4289 battery allows you to move freely about so that you can use it anywhere in the house or even outdoors! Getting a battery with a higher amp rating is OK, as it suggests the battery will last a bit longer on one charge. What really is critical to a battery fitting your laptop is the actual size of the battery and the connection it has. Not all batteries are the same, be sure to check the physical connection and size and compare it to the old one. The more power the battery has, the longer it will last when fully charged.
Simple indications of a poorly performing li-ion battery
- The battery gets puffy and looking like it is going to burst
- The Lenovo laptop will not turn on at all when unplugged
- The laptop lasts under ten minutes while unplugged
