My uncle recently lent me his laptop indefinatly since I'm still in school and he rarely uses it, but there is a problem. The battery life is only 2ish hours max, which is hardly useful considering how long the school day lasts. So I was wondering if anyone could direct me to a good battery that would make the laptop last hopefully quite a bit longer than it does now.

The Laptop is a Dell Latitude D800, and I have roughly $150-$200 to spend.

Any suggestions?

Kvestion: is this going to be your primary computer?

If not, I'd acquire another $200 and buy an Asus EEE PC.

... I have not had pleasant experiences with Dell laptops. :smallsigh:

My Aspire 4720Z has a battery life of 30 minutes...:smallannoyed:
It's more a small, very low spec personal computer than a laptop.:smallsigh:

Chameleon, laptop batteries are going to be three hours at the max. Also, the batteries are rather specialised and rather expensive.

Just bring the cord and keep charging it.

Well, the easiest solution (although not necessarily the best) would be to just buy some more batteries, and swap out the dead one throughout the day. But if your battery is behind, say, some obnoxious cover with a rare screw head, you could run into problems. Either way, this (http://www.amadvance.com/Battery-for-Laptop/Dell/Battery-for-Dell-Latitude-p4508569.html) should fit the bill nicely. Actually, if you don't already have a spare battery, you might want to consider getting it anyway. Potentially, your current battery could just be at the end of its life...

You should also check your laptop's settings and make sure that it's running as energy efficiently as possible. Turn down brightness and stuff. Does it have a big screen? Because those tend to be the biggest power drains.

Just be sure to get one from a reputable website. There have been quite a few stories of laptop batteries exploding on the news. Some of the reputable websites I use are: Dell.com, Zipzoomfly.com, Tigerdirect.com, and Newegg.com

Dell charges way too much for their batteries (I think it'd have cost me $300 for mine). I found a third party on Amazon for $80, and I know a battery store around here sells Rayovac ones for the same.

Just take the cord with you, it shouldn't be big of a deal, should it?

My computer has a battery of like 1.2 hours, so be happy with what you have.

My macbook has around 4 hours on it at low brightness, 3 if on full.

My macbook pro has about 5-7 hours, depending on screen brightness and on how much I use the screen.

The laptops from acer, especially their batteries, often suffer Constituition damage if you overcharge them.

Mine is 1 Con left and if you pluck out the cleric, it dies. My advice to you is to bring the cleric with you to school, then plug it in a rest shrine whenever you can. :thog:

Nemo (my EEE PC) has 7 hours of battery life max (usually works out to about 5-6 normally).

If you can't see your way clear to a non-Dell laptop, then I'd recommend scoping out your classrooms for outlets (there's bound to be at least 1 in range of a desk you can sit at).

I've never even heard of laptops running that long without a cord...

Mine's a Toshiba Sattalite (refebished for $250; great deal for a comp with 3 gigs of ram and 250 HD), and it runs for 2-3 hours.

just bring the cord to charge it when you need to.

Bringing the cord is a good idea. Problem with laptops is that the batteries tend to run out fast once you do anything that is processor intensive (games, but also Photoshop and other programs that need to make a lot of calculations).
