Works great *by L***D on November 11, 2024* My OEM battery wouldn’t hold charge for more than a few minutes. This swapped out quickly (and there are plenty of online videos to help if you need it); and the battery now last for hours again ### ⭐⭐⭐⭐⭐ Quick and easy way to restore battery life *by R***T on April 17, 2024* I bought this to help a friend with her laptop, she was at a point that she could only go about 10 minutes without a charger cable. On replacement her laptop will run for a couple hours with no issue. It was a straightforward installation that only took about 15 minutes. ### ⭐⭐⭐⭐⭐ Amazing! Laptop works better than new. *by J***H on October 6, 2024* I like the fact that the battery came with the tiny screwdrivers necessary for replacement.
