The battery life was a great upgrade... once. Then the battery would not recharge. In the process of returning it. (Laptop: Dell Precision M4600)

Purchase these on a regular basis - they work well

Bad product. Failed only 3 months, after the return period ended. While I sometimes buy third party batteries, over the last 6-8 months the quality from many sellers has been crap. Better to by directly from laptop manufacturer and get an actual warranty and quality product.

Good value, perfect fit

Purchased this product the first time and it wouldn't charge, so returned and ordered again hoping it was just a fluke, but it wasn't. Second one worked no better than the first, so I had to return it also. Don't waste your time!

This battery has never worked for me. What a waste of my money. I do not recommend you buy this knock-off battery. My expectation is that this battery was not tested.

This battery after fully recharged, it does not work at all. This is a trash.

Didn't work and wouldn't charge. I got ripped off!
