This review is from: (9-cell) Laptop Battery for Dell Inspiron 1520 1521 1720 1721 Vostro 1500 1700 Series Pn 312-0504 312-0513 312-0518 312-0520 (Electronics)

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.

This review is from: (9-cell) Laptop Battery for Dell Inspiron 1520 1521 1720 1721 Vostro 1500 1700 Series Pn 312-0504 312-0513 312-0518 312-0520 (Electronics)

I bought this battery for my Dell Vostro 1500. Everything seemed to work fine the first 45 days or so. Then for no apparent reason this battery died. Just like that.

This battery comes with a one year warranty. So I contacted Amazon customer service. Of course, I am out of their 30 day period to send it back. They asked me to contact the manufacturer (NG). Amazon doesn't even know what NG is, and what the contact info is. They asked me to contact the seller (Westronics).

I called Westronics. Left them a voicemail. Haven't heard back from them yet. If there is any progress I'll update this review. But for now, this battery is a piece of junk and customer service is the worst.

3.0 out of 5 stars Not as good as my original Dell battery!, August 4, 2009

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.
