After eight months of use the battery swelled up.  I'm happy to say that this vendor honors their warranty and sent me a replacement battery right away with no hassle.  I'm thankful for this.

After installing this battery, I find that my laptop is running slower than before. My laptop shows 2 batteries and 1 of them not installed. Other than that the battery life was better
