The lithium iron battery for this conputer is 4000 mA/hrs. or 4 Ampere hours. That means that with a draw of 1 Ampere the computer would be useable off the battery for 4 hours. Since you can't run off the battery below a certain voltage you can deduct 20% leaving a battery life of a little over three hours.
Testimonial: "thanks for your expert opinoion. i hope you can suggest a compatible battery that would last for 3 hours atleast for the compaq presario CQ41-207AU"
Maybe a battery from this site will help, but check the capacity (Amp/hr) of your current battery first. The length of time a battery lasts is very dependent on how you use the computer. that is If you use the drives a lot, the battery will go flat sooner.

NO thats about the best you can get really. The best thing is to adjust your power profile to get the best battery life, also Charging it up, should always be done, Over night,if possible, whenever you use ON Battery alone, Recharge, the battery up each, night, try and develop a "Cycle" this will help lengthen the life of the battery.

SOURCE: Compaq presario r3000 amd athlon laptop cuts off after 10 minutes
from my experience this might be one of two things...
if it's shutting down while you're installing windows, i'm thinking you might have a problem with the motherboard channel for your CD drive. i saw this happen to a computer at work - we couldn't install windows because it cut off halfway through and blue screened on us.
it might also be a case of a bad hard drive, if you have any testing utility like drive fitness test i'd give that a shot. it sounds like a new one, but they're bad out of the box sometimes.
hope this helps
