My take of the batteries
on September 16, 2026
Posted by: MyaK
My boyfriend has already done a review on here about the Duracell batteries, and personally both of us love them, especially for controllers, they're long-lasting and were great. Um, my first impression, obviously I feel like everybody's been surrounded by Duracell batteries since they were little, um. Just use it for anything that you need batteries in. I have a LED lamp up there, Hello Kitty one, and it lasts a really long time with the Duracell batteries. It stayed on for like a week straight. It's great.
