1 out of 5 eggsMine was junk

4 out of 5 eggsSo far so good

Pros: Cheap, fits well, almost indistinguishable from the Dell version.

Cons: Seems to give somewhat less time than what I remember from the original battery, but this could be from my computer not running as efficiently as it did 3 years ago.

Other Thoughts: I plan to treat this battery well, and if it gives out on me before a reasonable amount of time I'll note it.

5 out of 5 eggsGood Battery

Pros: Powers the laptop- has a good battery life, over 3 hours of typical office application work. I installed this as a replacement on two Dell Latitude D531 laptops in a work environment. Both have performed well.

Cons: None.

Other Thoughts: As always Newegg shipped promptly, and the product arrived in good condition.

5 out of 5 eggsGreat Replacement Battery

Pros: Ordered several of these to replace dead batteries in the D830 and D531 laptops we currently use at our business. They fit perfectly and have given us no troubles so far.

Cons: None!

Other Thoughts: These are almost HALF the price of the "official" manufacturer batteries that Dell sells on their website. Shipping was prompt and packaging was great. Will definitely order more of these in the future from Newegg!
