I bought this battery after a cord around. Plugged in laptops look foolish. We are in the era of nine cell yo! Dell and Batteries Plus want 130+ dollars for a replacement. I have had this replacement battery for 3+ months and it holds a 4 hour charge no sweat! Box comes with explicit charge/discharge instructions and tips for maximizing lifespan. Consider this battery and company for your future purchases. I didn't expect much and have gotten a solid replacement. Thank you.
Amazing life. It is better than battery as some sellers sell the original dell battery much cheaper Dell Inspiron 6400 Lithium Ion Battery. No problems at all. It works for average 2.5 hours.
I wasn't sure about this given some poor reviews on similar generic batteries, but this works quite well. It lasts as long as the original battery did (about 3-4 hours under light use--e.g., word processing, e-mails).
I have been using the battery for a little over a month now and I am generaly happy with the results. The power lasts at least as long as the OEM Dell battery did when it was new and it appears to be working just fine.
