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 was in excellent shape.
The product exceeded my expectations.
I would highly recommend doing business again with this company and surf their website frequently.

My old stock battery only held a charge for 20 minutes’ worth of use, so I definitely needed a new one. When I saw this one, it was an easy choice. Being a 9-cell, it’s important to remember that it will stick out a bit (roughly an inch) from the back of your laptop; I do not see this as a con.
My laptop (Vostro 1500) accepted it without the slightest difficulty, and sliding it into the battery slot was effortless. Even after the recommended breaking in process (which was presented in badly translated English), it does not last as long as I had hoped. I can get two to three (somewhere in the middle) hours of moderate use from a full charge, which is still a marked improvement. The computer’s power gauge estimate of how long the battery lasts is not accurate, sadly. It believes the charge lasts longer than it really does, and the battery dies around the 10% mark (though when I plug it in and turn it back on, it properly reports the approximately 0% reading). There may be a way to fix this, but I don’t know it.
All things considered, this is probably not the highest quality battery you can find, but it’s more than worth it for the price.
