Review: Decent replacement battery with a good price. - Exact fit for my wife's laptop. Swap was easy, included screwdrivers weren't the best. I used my own to avoid stripping out screw heads, but they will do the job, the spudger tool was adequate to separate the case as well. Battery charged fine and seems to work well. Time will tell how good it's longevity is, but for the price it worked out great!
Review: Great replacement for a weak or dead battery in Dell Laptop. - replaced a truly dead battery in my Dell laptop. Followed the instructions and used the laptop on battery only for a two hour meeting. Still had a significant charge left when I was done. Quite happy with fit, function and happy with the price.
