I was hoping it would last a bit longer, but it does last three or four hours. I work online so this is merely for using the internet and not, say, watching DVDs or listening to music, it is really very durable. the stamina is recommended.

had this battery for about a month ,it seems that it has a slight worse capability of power storage.

Same power (5200 mAh), same fit, same finish, same everything as the original battery. Works great. Computer doesn't complain about aftermarket battery. i was very satified whti this item.thanks a lot.

I wasn't that impressed with the life of the Dell battery so I thought why not save some money here? My battery was fully developed. Go ahead and buy this battery with confidence and pat yourself on the back for being smart .while a little patience for receiving.

purchased this battery to replace a toasted laptop battery. I am surprised at the life I get out of my T41 running Ubuntu 9.04. With other laptops I usually keep my power supply close by for when my battery dies abruptly (i.e. it says 10 minutes and the next moment "I am shutting down messages"). This battery has been running great. I have not had the sudden power drops like described.highly recommended.

The battery was delivered very fast.when installing it, my laptop works great. It has a great service, excellent product for the price. I would recommend this seller to everybody.

I bought these about half year ago and have used them about 10-15 times. compared with my old ones ,I find it has much longer time.
