Dell Latitude C640 Battery
Your Dell Latitude C640 battery makes your laptop portable so that you can use it anywhere in the house or even outdoors! Not all batteries are 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. Getting a battery with a higher amp rating is OK, as it just means the battery will last longer. What is important is the actual size of the battery and the connection it has. More amps in a battery basically means the longer you will be able to use the laptop on one charge.
How do you know if your battery has gone bad?
- The laptop lasts less than an hour while unplugged
- The unit is unable to boot up while not connected to the AC adapter
- The laptop battery has its case swollen like its about to burst
