Great value battery, although it lasts 2 hours instead of the 6 like my original battery. I wouldn't mind buying another in a year or two when the battery dies on me.

If you expect this battery to perform like the original, do NOT buy it. Right now I am lucky to get 4 hours before it is time to recharge. When new, the battery life was about 75% of the o.e.m.

What can you say about a battery, it either works or it doesn't. Windows didn't like it with no battery even when plugged in.

My computer was running slow, I kept getting an error message that my battery was low, I check several places for a replacement battery glad I found just the right one on Amazon at an amazing price. I installed it on my computer it gave my computer a brand new life, loving the product would recommend to everyone.

Good replacement, doesn't last as long as the original but it still holds about 2 hours of charge on average.

So far so good! My HP would only run when plugged in and that's not always convenient. This was perfect, popped it right in and gave it a charge and I'm back up and running! Great price too. I get almost 5 hours of constant use before needing to charge it up. Happy me!

I purchased this battery and the battery life was ok. It didn't fit flush to the bottom of the computer and inserted with more force then the original. After 4 months the battery is junk. Doesn't keep or take a charge. One day it was working fine and the next day as soon as the computer AC cord was unplugged my computer turned off. Did a battery test and the battery is junk. Their warranty is for 3 months for a reason. DO NOT BUY THIS. I attempted to contact customer service to see if they could do anything about it and they did not respond. Don't waste your money on this product.

I bought this CWK replacement battery 2+ months ago and couldn't be happier. The lower price was great and the quality was even better. The order was shipped quickly and arrived in perfect condition. This battery out performs my original HP battery in every regard and fits my laptop exactly. I will definitely go with another CWK product when the opportunity arrives. I highly recommend this product and the company based on this purchase.
