Lenovo ThinkPad 720 Battery
Your Lenovo ThinkPad 720 battery makes your laptop portable which gives you the opportunity to use it inside, outside or anywhere your heart desires. Because no battery is the same, make sure and double-check the model number and compare it to the old battery. Buying a battery with a higher milliamp rating is fine, it simply means it is a stronger battery. What really is critical to a battery fitting your laptop is the actual size of the battery and the connection it has. The more power the battery has, the longer it will last when fully charged.
