When your Dell laptop battery starts to reach it's end of life don't waste your time clicking on the link that is provided in the battey monitor message. It will just take you to the Dell website where you will pay twice as much as the cost of this battery. I have had this battery for several months now and have received great performance from it. Thanks MLC and Amazon! You have a customer for life.

I charged this battery for six hours. As soon as the a/c plug was withdrawn, the computer screen went black. My wifi connection was intermittent while the battery was installed. The charge lite flickered amber to white, something I've not seen before and this machine is approaching it's third birthday. All in all it's been a bizarre experience. I was apprehensive buying a high mortality item used and learned yet another life lesson. I guess I should have known when I couldn't find any warranty information and when I asked Amazon, got a rather vague and unsatisfying "You may return an item for 30 days." I again noticed that that 30 days begins with the date or your order. When you take free shipping and it takes 10 calendar days, 5-7 business/shipping days and you get 30 to return defective items, you lose almost half your warranty/return period. The warrantyreturn period uses calendar days but measure delivery in business days so you lose weekends. Seems a bit of a double standard doesn't it? I hope these reviews are read by the powers that be so they realize we realize this is unfair and stacked against us. How would they feel if the went to a store and bought something and were told "Oh by the way, your warranty/return period began a week ago" ? Thanks and good luck...

I haven't had this battery very long, but it is working as I expected and was a heck of a lot cheaper then buying from Dell.

I am so glad I found this replacement battery here because I refused to pay $150.00 from Dell. This battery works well and it serves it purpose. I don't know about it being extended capacity... but I am never too far from an outlet so it doesn't matter...If you aren't sure about buying this... I say go for it. You can't beat the price...

Oh, and thanks to all the others who left feedback.. It really helped me make my decision. :-)

The battery came in time and package was OK and that's the only good thing about it.
It was 70% full when I installed it and within less than one month it was slowly but surelly discharging untill died completelly. So you really get what you pay for.

Overall I am happy with the battery. I was a little disappointed with the battery life. It's a high capacity 9-cell but doesn't last much longer than the factory 6-cell that came with the laptop. The indicator button on the battery itself also does not function. However, for the price I think this battery is a good bargain and would still recommend it for someone who's looking for a decent replacement battery.

My Studio 17 battery was never good to begin with, I would get about an hour on a full charge. After buying this battery to replace the stock one it is like night and day. This battery lasts 4 times as long. I have only had it for a few weeks but its performance has been pretty impressive compared to the stock dell battery. If you need a replacement or an upgrade I highly recommend this battery.

This is a very large battery for my very large laptop. Running a 17" PC laptop with HD, "bright," glossy screen takes a LOT of power, and this battery will only last a couple of hours on it. Makes me shudder to think what a normal laptop battery would do.
The pitfall is the lifespan. My last one, which was the exact same battery bought brand new with my laptop, only lasted just somewhat over a year, at which time it starts to have very short battery life. You would think something of this size and price could have a longer lifespan. I may be foolish to think so.
It's also a very expensive battery. The $50 I paid here on Amazon is rather reasonable, but the $150 Dell price-tag is incredible.
Good battery. It will do. Won't make me super excited to turn my computer on...
