## Customer Reviews

### ⭐⭐⭐⭐⭐ so far so good
*by K***N on August 1, 2024*

Got me back to work!

### ⭐⭐⭐⭐⭐ Great replacement!
*by L***S on June 13, 2023*

Laptop powered up and the battery had 49% out of the box. It allowed me enough time to troubleshoot, and figure out why it wasn't charging, even though the power adapter was warm. It looks like the power socket is the problem. I'm hoping it's the lug, because if it's the socket, I'm doomed.We will see. However, this battery is great, and I would recommend i.
