Compaq NX8220 Battery
Your Compaq NX8220 battery makes your laptop portable so that you can use it where you want. Because no battery is the same, make sure and double-check the part number of the new battery and compare it to the one you are going to replace. More amps in a battery basically means the longer it will last on one charge. It is OK to buy a battery with more milliamps, as it just means the battery will last longer. What is important is the physical size of the battery as well as the connection.
Simple indications of a failing Compaq battery
- The battery is puffed up and looking like it is going to burst
- The laptop lasts under ten minutes before it shuts itself down
- The Compaq laptop is unable to boot up at all when unplugged
