Lenovo G40-70 Battery
Your Lenovo G40-70 battery allows you to move freely about which gives you the opportunity to use it anywhere you please. Buying a battery with a higher milliamp rating is fine, as it just means the battery will last longer. What is truly important is the connection type and physical size of the battery. The more power the battery has, the longer it will last when fully charged. Because no battery is the same, be sure to check the size and model number in order to make sure it is similar to the old one.
Simple signals your battery is dead
- The Lenovo laptop is unable to boot up while not connected to the AC adapter
- The laptop lasts under 20 minutes while using the battery only
- The laptop battery gets puffy and looks like it will explode
