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 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.

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.

Despite their claims, this battery does NOT fit correctly in an Inspiron 1720. It is just loose enough to lose contact when I transport my laptop in its case. When I try to awake the computer from hibernation, it ALWAYS reboots completely, telling me Windows did not shut down properly. I lose all my open windows, work-in-progress,etc -- all the advantages of hibernation. Not sure about other models, but AVOID this battery for an Inspiron 1720.

DON'T WASTE YOUR MONEY AND TIME!!!! This battery charged 100% when first received and within 3 weeks was down to 33%! Now another week and it is at 30%, at this rate will be gone in the next month. $35.00 for two months is too expensive. It will not hold a charge and the company will not reply to emails. DON'T WASTE YOUR MONEY!!

I have a 3 year old Inspiron 1520 and my battery life has been hovering around 1.5 hours. I wanted to get a replacement battery since my battery health was around 47%. This battery worked for 3 days and, when it reached 40% charge, it would plummet to 1%. This battery held even less charge than my old one. I have sent it back for a refund and I would not recommend getting this.

Also, it is worth mentioning that this battery does NOT has the same charge compared to Dell's OEM 9 Cell battery. This battery is 7200mAh, Dell's battery is 8500 mAh.

I am very mad about this battery. I ordered it in June 2010 and now in October 2010 it is already pretty much useless. If my battery says half full my computer shuts off. This battery will most likely not last you. It's garbage. A product needs to last longer than 4 months!! You might want to consider buying the dell battery as they might back up their product for longer than 4 months. At this point it's like a disposal battery and I'll most likely have to purchase the more expensive dell battery anyway. Very unsatisfied with this product.

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.

Good battery. Fit perfectly. Not quite as good performance as my original dell 9-cell (now 4.5 hrs instead of original 5+), but at 1/5th of the price I am completely satisfied with this product. Please note that this is the 9-CELL battery and will stick out the back. Some people seem upset that this battery sticks out the back and their old one did not. The 6-cell does not stick out like the 9-cell. Please do not rate this product low because the battery sticks out. This is due to the design by DELL and not because of this specific battery.

I would definitely recommend this product.

Edit: Its almost 2 years later and this battery is toast. I get maybe 15 minutes out of it now. I would say it lasted a little over a year and a half before the time left on the battery became to short to use off of A/C power. This battery lasted maybe 1/2 to 3/4 of the time I had the original battery. It should be noted that I am hard on batteries. I'm bad at doing full charges/discharges. However, this does not change my rating. You cannot beat the price. Dell does not sell the 9-cell battery for my 1520 anymore and the 6-cell is $136. I will be purchasing another one soon.

replacement for wifes laptop battery. works fine. does extend a bit from the back, about 1".
