Hello Baxxter I have never used one of these batteries but a look here makes me think it is not worth the money; DELL 85 WHr 9-Cell Lithium-Ion Battery for Dell Latitude D620 Laptop : Laptop Accessories | Dell

Look at the ratings tab

Have both and 5 hours is more realistic unless you want to cut performance and use power saver mode.

Have a Dell and a 9 cell battery and it cannot in any way run 9 hours. The best I have accomplished is 6 but that is in power saver at a 40 % reduction in performance so for me it is not an option.

HP's are similar.

Both of the above do not consider the price. Dells list is $155.

My wife has a 12 cell battery in her HP laptop and she gets about 7-8 hours on a charge. I have a 9 cell on my Dell laptop and at standard power saving settings, I get about 5-6 hours.

Im a mac user when it comes to laptops, and i get about 8 hours battery from my 13" macbook, if i boot it into windows i only get 2-3hours on a full charge.

In my case, the 12 cell is an HP similar to this one;

That battery is going to make the laptop weigh a ton.

 

[pparks1]

The 6 cell battery for my wife's HP is listed at .7lbs. Her new 12 cell battery is 1.7lbs. So, it added 1lb. Which is a lot, if you are talking about a 5lb laptop..about 20% of the total weight.

You need to be much more specific

What 15" with what processor, etc. You can get all the info from the mfr of the computer you are considering.

These are high estimates. My usual time on a Dell 15" with 9 cell battery is usually around 5 hours.

Go to the mfr. They are the most accurate source of info for your system. You can actually calculate how long it would last if you really want to do a ton of work.
