Lenovo G40-30 Battery
Your Lenovo G40-30 battery makes your laptop portable so that you can use it anywhere you please. More amps in a battery basically means the longer you will be able to use the laptop on one charge. Because no battery is the same, be sure to check the model number and compare it to the one you are going to replace. Getting a battery with a higher amp rating is OK, it simply means it is a stronger battery. What really is critical to a battery fitting your laptop is the physical size of the battery as well as the connection.
Symptoms your battery has very little life left
- The laptop lasts under ten minutes while using the battery only
- The battery has its case swollen and looking like it is going to burst
- The unit will not turn on when it is unplugged
