Besides the slightly under capacity battery, the other flaws that this battery has is it's fit in the laptop and the rubber stoppers. The fit has some really small slight jiggle to it. Also the rubber stoppers on the bottom of the battery are noticeable larger than the rubber stoppers on the original battery. Another thing with the stoppers is that the adhesive of the rubber stoppers to the battery is really poor. There's two under there and both came out when transferring laptop to a backpack. I've fixed it using gorilla glue and so far it's been sticking on.
Overall I believe this is a good deal. Dollar per mAh ratio is better than the original and there isn't much of a bigger difference in capacity from the original dell battery to this one.
My original Dell 9-cell 8400mAh battery was down to around 20% capacity, it would only last about 30 minutes. The only 8400mAh replacements are from Dell and cost an arm and a leg, I figured a 7800mAh capacity would suffice.
I got the battery quickly and installed it, worked fine. I ran the Dell diagnostics on the battery to test the capacity and it was only 6600mAh.
To run battery diagnostics in Windows 7, open your command prompt and type "powercfg -energy" and press enter. It will run for 60 seconds and create a report that will display the battery capacity and other information.
The seller let me return the battery for a full refund (Thanks!) and they told me they would revise the listing. They have not, but I will delete this review once they do. If you have already purchased this battery then I advise you to check its capacity.
Then I plugged it in, charged it, and started my machine. This baby holds a 4-hour charge! Which is impressive for the amount of resources my computer uses. That was 4 months ago... Now I'll be lucky if the charge lasts me through an hour-long meeting.
This battery is okay for the price, but its charge will rapidly reduce over time. Unless you're trying to squeeze the last few weeks out of your laptop's usable life, you should probably go with a better (and probably more expensive) battery.
My opinion (from a guy who dealt with laptops for 15 years)- You are likely purchasing a used product that has been furnished. For a battery, that is terrible. Do not go with this buyer.
Don't waste your money!
