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.

I put this battery in my laptop after dealing with horrendous battery issues in the past. This was a great purchase, and I can now unplug my laptop with confidence that it won't immediately shut off! This battery arrived almost fully-charged as well! (Posted on 10/26/2015)
A low cost replacement battery Review by Kelly
How do you rate this product?
Bought this to replace an ailing HP Pavilion's original battery that died out after 2 years. Very well priced compared to others I found through an internet search and is providing >4 hours of working time which is comparable to what I got out of the original battery. So far, so good.

This replacement battery came with my battery charger. Perfect fit and didn't know I really needed a new one. But when I changed batteries, my laptop ran a lot faster. I gave this battery a 5 star rating because it was what I needed and it works/fits perfectly (Posted on 9/29/2015)

This has worked excellently for the laptop Review by Pinney
How do you rate this product?
Well for those of you who have said nay, this is a yeah for me. It has revived my older laptop to be able to use again. Thought at first the power supply, but it was indeed the battery. This has worked excellently for the laptop and I would definitely recommend the purchase. No problems and have had over a month. (Posted on 9/20/2015)
Amazing battery and service! Review by Patricia K. Cook
How do you rate this product?
Fast shipper. Battery life is about 4-6hrs. Using for HP dm4-2070us. Whenever I need another battery i would purchase from this company again, almost as the same as the price of an hp but worth the money! (Posted on 8/27/2015)
