<p>Which laptops have battery life in the 3 to 4 hour range? Or should I just buy an extra battery to swap in?</p>
<p>my lenovo t61 can stand up to 3-4 hours (balanced performance). record is 5 hours if i’m using max battery setting</p>
<p>My HP pavilion dv6000 can go 4-5 hours, but that’s with the 12 cell battery.</p>
<p>My Sony Vaio CR220 tops out at just over 4 hours on a battery saver setting.</p>
<p>I’ve gotten nearly 6 hours with my 9-cell battery. I’ve got a Dell Inspiron 1501</p>
<p>Dell XPS’s can get about 4-5 hours on the 9 cell battery when just surfing the web or typing.</p>
<p>2.5 hours on my HP Pavilion dv9700t ;)</p>
