I've had this battery for just a day, but I'm very happy with the performance so far. I run an HP Dv9000t with Vista Ultimate, so it demands a lot of power. Depending upon what I'm doing, I can get around 3 solid hours from this battery versus the one installed by HP which got around 2 or less. Also, this 12 cell is a fair bit cheaper than standard HP 9 cell. If you don't mind the extra weight and bulk (which bulges out from the bottom of the laptop) than this is the far superior battery.

This is a good replacement battery, although it is a little annoying at times the way it sticks out. My laptop is already a pretty large one and this makes it even more bulky. However, I knew it would be like that when I bought it. The positive is that it helps keep the computer cooler by creating extra space underneath.

I bought this product about a week ago and it has worked quite well. I have been looking for a bigger battery since the 8-cell's wear was about 20%. Though I know I didn't need a new battery yet, I felt that it would be nice to have some more battery life. I am running windows 7 (beta build 7100), I have the core 2 duo 2.4 GHz processor, 8600m GS graphics card, and 7200 rpm hard drives. Well, on power saver mode my computer is underclocked to 792 MHz, and I have undervolted my processor to as low as it could go without crashing. I was able to get a respectable 3 hours and 30 minutes out of my 8-cell (I use Batterybar to determine life), but then I got this battery and my life jumped to about 6 hours just typing and reading pdf's (which is what I primarily do at my university). When I surf the internet and the computer runs more my battery life is about 4:30-5:00. Also, the computer being lifted has made it a little more comfortable to type as well letting the cooling be much more effective. And finally, the shipping was surprisingly fast, only took 3 days to get to my house.

I ordered one of these batteries several weeks ago. After recycling it four times, it lasted only about two hours. I ran HP's battery check and the battery tested as defective. I returned the battery to Brilliant Store and it was promptly replaced. The second battery was recycled 4 times and the battery check run. Battery check indicated that this one had bad cells and that it should be replaced. This was sent back for a prompt refund. Still I am out about $20 for postage for the original order and returns. I am now trying a Ray-O-Vac purchased locally. If it doesn't work, I can return it without postage.

I purchased this battery a few months ago to replace the original HP battery for my DV9000 laptop. Shipping was incredible, it arrived alot faster than I thought it would.

The battery provides outstanding performance. It last a lot longer than the original. It's a little heavy, but what can you expect from a 12 cell battery.

I would definitely recommend this battery to anyone.
