## Customer Reviews

### ⭐⭐⭐⭐⭐ New laptop battery.
*by A***R on July 4, 2024*

Works great. Started immediately even without first charge. Fit my laptop perfectly!

### ⭐⭐⭐⭐⭐ Replacement for my old stand-by
*by D***E on January 21, 2023*

The battery in my old Dell laptop was not charging anymore. The old Dell is almost 10years old but still works great. Replaced with this battery and it works. I think it even works a little faster with this battery. Battery fits and stays charged

### ⭐⭐⭐⭐ Affordable
*by P***S on December 9, 2018*

Price is great, installed easily, I am not sure how long it will last so therefore I don’t want to say so far I’m happy with the purchase
