Answers:4 Cell Battery: 1.5 to 2.0 hours 6 Cell Battery: 2.5 to 3.0 hours 9 Cell Battery: 3.5 to 4.0 hours The actual battery life will vary depending on the battery size, computer configuration, and how the computer is used.
Answers:A cell and a battery are really the same thing. Technically, the word 'battery' means a collection of things, so really a 'battery' should be multiple cells. When the word came about, that's what it was. You couldn't just plug into the wall and get 100 or 200 volts, so for anything more than 1 or 2 volts you needed multiple cells, a 'battery' of cells. The French word is 'piles', which also means several things of the same kind. But over the years the meaning of the word changed. Today we use the word 'battery' for one single cell, like an AA battery. A 9-volt battery has several cells in it (6 cells, each one being 1.5 v.), so it really is a 'battery' in the original sense.
