Rated 5 out of 5 by from Great power! I used these for my radio and lamps for power outages during hurricane season. I am moving away from so many candles to bright lights that operate with batteries. I love the candles but my allergies not so much.

Rated 5 out of 5 by from Keep on going! I am so happy I got to try out Rayovac's D Fusion Batteries. They work well to power my devices, and keep going strong. A few I love about these batteries is the they have a 12 year power guarantee in storage, and a leak-proof guarantee. It makes me feel better about keeping them on hand and using them. I couldn't ask for more!

Rated 5 out of 5 by from Long lasting batteries I am using the Rayovac Fusion D size batteries in a toy of my son's. They last longer than other brands. Only downside? I get to hear is toy play music and talk all day long. I'm kidding. These have been a sanity saver for when my son cries that his toy has "died".
