I was apprehensive at first in selecting your site for my battery replacement, but after receiving and using the battery I must say that I am very, very pleased with the results.
In short:
1. the battery works
2. the battery fits
3. the battery blends in well
4. and the battery was REASONABLY priced
It began working as soon as I placed it in my laptop.
Thank you for such an amazing product. I will purchase here again in the future.


This fits perfectly. I've had this for 3 months and no problems at all. Received the product very quickly. Very inexpensive for a battery that still works. It even lasts longer then my previous battery. A great buy!
