Discover Why LaptopBatteryOne's HP Batteries Will Keep Your Laptop Working for Years

Is your laptop's life span just not what it used to be? Laptop batteries are like other batteries - eventually and inevitably, they get used up. The average battery gets up to 500 charges or life cycles. Now, what you should do is invest in a high quality battery. You'll want to avoid cheap low quality replacement ones as they don't last and can potentially cause a fire.

LaptopBatteryOne's premium HP batteries, for example, are some of the very best and provide long run-times. They contain the same reliable components as the original HP batteries, often outperforming the original battery itself.

This battery is manufactured using the highest quality battery cells with integrated charge indicator LEDs. Depending on the capacity you've selected some upgrades last up to 68% longer than the factory issued laptop battery. This battery will perform better and fit more snugly than anything else on the market.

LOVE IT! Review by Mandy
How do you rate this product?
I've only been using it for 2 days but it seems to be a great battery. When I bought my laptop brand-new a few years back the factory battery was already dying. It got to the point where I could never unplug my computer from the charger because it would instantly die. I purchased this battery and now I can now make my laptop portable again! I can have it off the charger for about and hour and fifteen minutes before needing to plug it back in, something that I have NEVER been able to do with this computer. Great investment!

This fit perfectly and has no problems Review by Linda
How do you rate this product?
THis was a good purchase, the battery fit exactly as it was supposed to and holds a charge throughout the day. My son uses the laptop primarily to record music videos and synthesize music tracks so he's on it a lot. This was a very good replacement battery, if I need a new one in the future I won't hesitate to repurchase this one. (Posted on 10/8/2015)
Happy Review by Jessie
How do you rate this product?
I originally had wanted a different part but I had this feeling that it was not going to fit my computer so I bought this one. My original battery wouldnt hold a charge from the very moment my sister and mother bought it for me. I never thought about it because school was starting and I just wanted to get the computer and start using it. Now that I have this replacement I dont charge it as much because it lasts me a day or so depending on how much I use my computer. (Posted on 9/29/2015)
Works great Review by Pam
How do you rate this product?
I purchased this for my existing laptop. It works great. I get about a 4 hour charge on it with the OEM battery giving about 5 hours, but for the price difference, I will gladly sacrifice the extra hour. There was a huge price difference between this battery and buying it from the manufacturer. I highly suggest it and have suggested it to one of my co-workers that needed a new battery.

Great for the price Review by Bob
How do you rate this product?
This battery is awesome for the price. It lasts about 4 hours (the original factory battery, when new, lasted just over 4.5 hours). For the price I have no complaints. It definitely did what I needed: extend the life of my 4 year old laptop one more year. I would definitely buy it again under the same circumstances. (Posted on 8/31/2015)
