5 out of 5 eggsWorks great

Pros: Was having issues with the stock battery overheating. This one works great and due to it being slightly higher, raises the back of my laptop which assists in cooling in general. This battery works great for my needs.

Cons: None really.

5 out of 5 eggsLong-lasting contender!!!

Pros: -Man does it last!!! Puts the stock Battery to shame.
-The power meter on the outside is genius: 3 sections = 3/4 full (about).
-You can charge it without having it in the laptop.

Cons: Zip
Zero
Nada

Other Thoughts: I keep this battery full as well as my original. That way, IF, note IF, this beast gets too low, then I can plug in the minutely powerful stock battery, and charge this up to 25% while the original drains pretty good. After that, re-swap to the beast and finish the class lecture notes!

5 out of 5 eggsHP KS526AA 12-Cell Extended Life Battery

Pros: Battery working very well.

Cons: See below.

Other Thoughts: Had to rma the first one I received. Upon unpacking the battery, the "meter" lights were constantly illuminated.

Pressing the battery "meter" button had no effect.

(Appeared to be shoddy packaging on Hp's part. They seem to be shipping these in package with the "meter" button depressed by the packaging.)

5 out of 5 eggs

Pros: The battery was a major upgrade from my 6-cell battery that was included with my laptop. With how I have my laptop setup, I can get a good 5+ hours on a single charge when doing light web browsing, compared to about 1.5 hours on the 6-cell battery

One major plus is how I can charge it separately from the laptop; using my laptop's AC. This is quite a nice feature; allowing you to charge this battery up while using a different one with your laptop.

Also, it standing up taller in the back is a plus; allowing for improved airflow to the fan (Which does make it run a bit cooler)

Cons: Because this battery adds extra bulk, it's harder to fit the laptop into a carry case; which could pose a problem for some

Other Thoughts: This was a great purchase

5 out of 5 eggsAnother good one!

Pros: High capacity, built-in battery meter, can charge outside of computer

Cons: none

Other Thoughts: Let me start by saying I'm hard on batteries. I run my laptop down several times per day and I have a high-performance (what some would call "gaming") laptop and run MANY things at once so my <2 hour runtime is atypical of an average user. I usually kill batteries at a rate of 1 per year. Even with that, on power-saver my 15.6-inch HP dv6t (Intel i7-720M+nVidia GT 320M) can easily get through a 3 hour class with one of these batteries and have some power to spare.

I purchased this to replace one that lost capacity after being heavily used for about 18 months. I have 2 of them in working condition and because of the charger port right on the battery, I can have one on charge while using the other and swap batteries when I get low. These do stick out the bottom but I personally find that an added benefit because it props the keyboard up and improves air circulation and cooling under the laptop.

Bottom line: This is the best extended battery I've ever owned for any computer.

4 out of 5 eggsOkay...

Pros: Extended life

Cons: Too clunky for the laptop model. Lifts the notebook, but seems to just get in the way.

Other Thoughts: Wish Newegg had the regular 6-cell for sale

5 out of 5 eggsWhat a great battery! LONG LIFE!

Pros: Picked this battery up a little under a year ago after my stock HP battery kicked the bucket. What a battery. Easily holds a charge for over 4 hours. It also charges fairly quickly.

Cons: It's large and heavy. If you can't carry a lot of weight and struggle with your laptop as it is, this is something to consider. It also prevents your laptop from being able to lay perfectly flat since it sticks out from the bottom. Overall this isn't really a big deal.

Other Thoughts: I recommend this battery for anybody whose laptop can fit it. It's a great buy.

4 out of 5 eggsVery satisfied with this battery!!

Pros: Long battery life. Works as a cooler for my laptop since there's some space between the battery and the base because of the big size. Works out good for me..

Cons: Was tricky to install the first time but once I got hold of the notch in my laptop it was easy.

5 out of 5 eggsWorks Well

Pros: I own an HP laptop with no cooling ports on the side, so the large size of this battery props it up and keeps it cool. I have owned this battery for over a year and it still lasts me 3+ hours on Power Saver.

Cons: None. Battery works great, even after a year.

Other Thoughts: Nice reliable battery, plus cooling my laptop, for a reasonable price.
