Panasonic CF-Y4 Battery
Your Panasonic CF-Y4 battery allows you to move freely about so as to work or play anywhere you please. Because no battery is the same, make sure and double-check the part number of the new battery and compare it to the old battery. It is OK to buy a battery with more milliamps, as it just means the battery will last longer. What really is critical to a battery fitting your laptop is the physical size of the battery as well as the connection. The larger the battery, the longer it will last on one charge.
What are some hints that my primary battery needs to be replaced?
- The laptop will not boot up while not connected to the AC adapter
- The battery is puffed up and looks like it will explode
- The laptop lasts less than an hour while unplugged
