My battery lasts for 2 hours after 2 weeks of use(after following best practices of charging/discharging) which I would consider poor performance even after relatively cheaper price as compared to Dell battery that would last for at least 4.5 hours after 3 months of usage. I had to struggle a lot to fit the battery on my Dell D620. I would think twice about buying cheap as it may also be cheap in performance. I could not locate the contact number for this vendor as they don't print it on their payment receipts. Why would any vendor not like to give its customers a customer service number to call unless they are expecting return of goods instead of repeat customers.

Physically, this item is nearly identical to the Dell branded battery. There are no quality issues at all. It does have the battery meter on the bottom, just like the original one. Since my Dell unit crapped out after 18mo, I can't do any side by side comparisons, but I think the original unit had a bit more capacity. I recall getting 4 hours on my D620 running Fedora Linux (thought that was for maybe the first couple months). This unit is maybe 3-3.5 but again, I haven't really done any scientific tests. It could be that I'm just harder on the battery now than I was then. Either way, it's a steal at roughly 1/3 the cost of the Dell unit.

there was no review and I was hesitant to place order but I did because of price. Once I received package within 3 days - I was very happy. almost getting 3.5+ hours of bettery life.... Great product... value for money!

This battery is cheap, it does not behave like a 9-cell, you have at most 2.5 hours of use as opposed to 4 from the original battery. Also this battery failed on me after only two weeks of use. The battery life was down to about 15 minutes. When it fails, good luck getting a replacement from one of these fly by night importers. Bottom line, you can't get a $150 dollar battery for $50.

It's been almost a year of regular use and I still have more than 3 hours of battery life! Had 5 hours when it arrived and that lasted for several months. Only downside, for some reason, after 25% use it thinks it's out of juice and it turns my computer off. But, my computer turns right back on without problem. Also, it doesn't exactly fit flush, but it's still better than the battery dell sent me with this laptop. GREAT PRODUCT!
