5.0 out of 5 stars Better than what I had expected., March 30, 2010

This review is from: HP KS526AA 12-Cell Multi Charge Extended Battery (Personal Computers)

With this being my second laptop to date, I know that the battery shipped with the unit is usually not enough. Although I had been getting about two hours on average with the battery that shipped with my HP Pavilion, I needed something more for those times when I expected to use the computer without access to an available AC outlet for more than two hours. This battery is far superior to anything else that I compared on the internet, and where I live the Computer Stores don't even carry extended life batteries for the laptops that they sell.

This battery has some of the extras not seen on off market batteries with lower price tags, and from Amazon.com with shipping was lower than some of the off market batteries that I compared it to. Although an extended battery is going to be larger that the original battery shipped with the computer (A little more than double the size), and obviously weighs more too, It is well worth having around because I am getting just under six hours on average with this unit.

This unit has two features that drew me to purchase it in the end - two features that I haven't come across before in an extended battery.
1.- On the side of this unit there is a battery check feature that utilizes a push button and four LED's in a circle to gauge the amount of power you have. For every one LED lit, you have twenty-five percent battery life left.
2.- On the top of the unit there is a port that accommodates Any standard HP branded, or HP brand compatible off market AC Charger. Therefore you have the option to charge your shipped OEM battery in your laptop while you charge the HP Extended battery without even being in the computer! An excellent idea for those that need to charge more than one battery at a time.

The height differential is nominal at best. Raises the back of the computer about 3/4 of an inch. Although I don't care about the difference in height for typing comfort even though an angle is recommended for typing comfort, The height differential is acceptable for increased airflow beneath the computer. My computer fans seem to be running less.

Now for the cons (there aren't many, and just something that is confusing) - On Amazon's website as well as HP's, this battery says that it is compatible with the following notebook Series: HP Pavilion: dv4, dv5, HP HDX: HDX 16 HP: G50, G60, G70 Compaq Presario: CQ40, CQ45, CQ50, CQ60 and CQ70. On HP's website that includes the dv6 model which I have. On the box when you receive it, it omits the dv6 compatibility even though it is compatible. Don't be confused.

In conclusion this battery is well worth the price through amazon.com. It is a lot cheaper than if you would buy it from HP Direct, and with the features that it includes is far superior to an off market external battery. I would recommend this to another HP laptop user, and even if all you are concerned about is having a battery for extra PC time, this battery is worth the price for the extra features that you have access to.

5.0 out of 5 stars Just what the doctor odered............, March 19, 2009

You think when you first by the laptop that the standard battery is enough. Then you start really working and going places and realize that 1 to 3 hours of battery power just "ain't cuttin' it" - especially on planes trips. You also find that power isn't available everywhere you go either. This battery does really good. Average of about 4 and half hours (I forget to change my power settings but ..... oh well.....) Form fact isn't too bad. Actually gives your laptop an upward tilt for more comfortable typing.

Abercrombie and Randy Leizear's reviews below really say it all, and Amazon's price with Prime shipping was the best for me. I use my lap top a lot and there's no way I could get by without this battery. I understand why the manufacturer doesn't give you this battery as original equipment as the cost of the computer would go up $80 to $100 just for the battery, but I couldn't use my laptop without this. I thought the stock battery would be enough -- I'd lived this long with it -- but after having this battery a while it makes things a lot more convenient.
