Battery question

[matrix563]

I have a dell D630 with a 9 cell extended battery. I am thinking about getting a 6 cell battery to go where the cd rom goes for extended battery life.

Currently with the 9 cell i get about 6.5 hours with wifi off and the lowest screen brightness, and almost 6 hours with wifi on and lowest screen brightness.

How much additional time am I looking at by adding a 6 cell battery to the laptop?

iv'e searched online and only came across this 1 comment:

My unit had a 9 cell and spare 6 cell modular battery, for 13 hours of battery life.

also saw this:

6 hours is a bit of an over estimate, I can get about 4-4.5 hours off of my 6 cell with the brightness down 5 notches, wireless on, and working with Firefox / Word sort of stuff. I've got the media bay battery as well, and Vista estimates about 10 hours of life with the same usage / settings, but I haven't done any actual tests. It's a long time.

I would say 4-4.5 hours would be a good estimate, considering the fairly limited knowledge I have of the D630, but I do know a friend who has one, and he has the 9 cell and the 6 cell, and says that 10 hours with brightness 50% and wifi on is not a problem. He's running Vista 32 bit Home Premium.
