Lenovo IdeaPad Z40-75 Battery
Your Lenovo IdeaPad Z40-75 battery makes your laptop portable so as to work or play anywhere you please. 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. Not all batteries are the same, make sure and double-check the physical connection and size and compare it to the one you are going to replace. The more power the battery has, the longer it will last on one charge.
Major clues of a weak li-ion battery
- The laptop does not run longer than one hour while using the battery only
- The battery gets puffy like its about to burst
