V Charged Up (Batteries)
One critical issue with the notebook
is the battery. Once the battery goes dead, you might as well
be hauling around a brick.
The first batteries for laptops (I
wont call them notebooks) were the lead-acid battery. This was
replaced by the Nickel-Cadmium (NiCd) battery. While weighing
less than the lead-acid, they have less total power between charges
NiCd Use it or Lose it
Your mantra for NiCd (pronounced NI-CAD) should be "Use it, or lose it." Recharging a Ni-Cad after a brief use, and repeating this process (say while taking the same short trip every day) will result in a battery that lasts exactly that long, regardless of rating. This is known as the memory effect.
What happens is a crystalline barrier forms around the metals right at the point of maximum discharge. The only way to 'save' a battery subject to this effect is to break the barrier with a small over voltage. How much over voltage is on a case-by-case event, and a dangerous experiment. You are NOT advised to try this at home, or the office.
