I have a Dell Inspiron 1520. My old battery only held about 30 minutes of charge so I decided it was time to get a new one. I was wary about purchasing the battery from pyrus electronics since it was so cheap. Nonetheless, the battery arrived on time and it works perfectly fine. When the battery is fully charged, I get about five to seven hours of power (depending on screen brightness, active programs, etc.).

Also, my battery fit perfectly into the slot. There was no force necessary as stated in a previous review.

I bought this product admittedly without reading carefully enough through the product description: I took myself to be buying an original Dell battery. When it arrived, it did not fit quite perfectly into my computer; it took an unhappy amount of force to get it situated. My computer (an Inspiron 1520) did indeed recognize the battery without any problem. However, it does not seem to power the computer for as long as my original Dell battery did, which would last for almost 6 hours when it was new. Perhaps this is because I have not yet "trained" the battery. But after the first charge and deplete and recharge, my battery meter now tells me that the freshly charged battery is good for about 4 and a half hours. That's not quite as good as I was hoping.

The product arrived within the time frame indicated by the seller.
The product was in excellent shape.
The product exceeded my expectations.
I would highly recommend doing business again with this company and surf their website frequently.

All I was looking for was a battery that would give this 2 year old Vostro a little more life, while I saved up to replace it. So far it's worked for about 2 months, and the battery life seems to be comparable - I use the laptop plugged in 90% of the time, so my requirements aren't as stressing as most, but for what I needed it's just right (and definitely the right price).

It has worked so far, the seller sent it out right away with a pretty guarantee for a compatible product, we'll see how long it works....I'd rexommend the seller.
