There are millions of laptop battery.Finding a right laptop battery is difficult to the laptop users.

Don't think all laptop batteries are created equal. There is no such things as a generic or universal laptop battery. They are all different and guess what... it is the best interest of the laptop vendors to keep it that way. No, a Dell laptop battery is not the same as an HP laptop battery, and you cannot use the cheap IBM Lion batteries you just bought to replace the Vaio laptop battery of your girlfriend. The shape, specifications, and size of most laptop batteries differ from one model to another, and I'm not even talking about the well-known exceptions such as the flashy Apple batteries or the heavy duty, water-proof, Panasonic toughbook batteries!

All laptop batteries have, however, a few characteristics that are the same:

- The laptop batteries can be recharged an infinite number of times, especially nowadays because they are generally built of li-ion or Nimh;

- The laptop batteries can be pretty pricey, especially for the higher end models such as the HP, 600e IBM, the Compaq laptop batteries, or the Acer replacement battery;

- The laptop batteries can be pretty delicate electronic components: do not be surprised if your battery suddenly drops voltage or the laptop battery won't charge fully;

- The laptop batteries have to be regularly charged and discharged to maintain their battery life.
