Compaq Evo N400C Battery
Your Compaq Evo N400C battery allows you to move freely about which gives you the opportunity to use it anywhere you please. The more power the battery has, the longer you will be able to use the laptop when fully charged. Not all batteries are the same, be sure to check the size and model number in order to make sure it is similar to the one you are going to replace. It is OK to buy a battery with more milliamps, as it signifies that the battery can last for a longer period of time on one charge. What is truly important is the connection type and physical size of the battery.
Main clues the li-ion battery is not going to last much longer
- The laptop battery is puffed up and looks like it will explode
- The unit will not boot up when not connected to the charger
- The laptop does not last longer than 45 minutes before it shuts itself down
