Review: Expectation matched. - I can’t complain about the product. The battery was packed really well. It matched the part I needed but unfortunately it was not the part that that fixed the problem. So now I have to decide if I want to spend more on the laptop than what it’s worth. I did like that it came with a tool set to help with installation a little easier.
Review: Very good - So far so good. Thanks!

So far so good. Thanks!

### ⭐⭐⭐⭐ SUNNEAR BN03XL Laptop Battery Replacement for HP Envy
*by W***G on September 7, 2023*

This battery is functioning fine. It's not easy to install these but that is because of the design on the laptop. It is not because of an issue with the battery. I have found the life to not be as good as expected. A fully charged battery will last for about 5 days. I cannot blame the battery for this as the old battery did not hold a charge for long at all. I think there are some leakages with the computer itself. This is probably not an issue with the battery. I was hoping to get much longer life with the new battery, but I cannot point to it being the problem.
