I purchased a use HP Elitebook laptop. After about 8 months the C-Mos battery finally went dead. I ordered this to replace the old. It works just fine. The price was reasonably priced and the shipping was satisfactory.

Great value for money.
Works great as of 2 weeks. It still holds a charge. It's very easy to install and good and has easy connectivity. ; you just need to plug it into the header. The battery life is still good, and it fits perfectly into the header. Overall, I recommend this 5/5 because of the great value for money.
