When you need to constantly use a high-powered device, such as flashlights, stereos, electronic faucets, or any wireless device like microphones, pagers, or computer equipment, the Fusion line is your best choice. The breakthrough zinc formula is designed to create better ion transfer, which means the battery can supply more powerful energy to your device. This makes these AA batteries particularly useful in heavy-duty applications where the batteries require frequent use.

    Thank you for your feedback! We’re sorry you did not prefer this product. For recommendations, please contact our Customer Solutions team.
    I used this for my flashlights. They lasted a good while (comparable to other battery brands) and no battery leaks as far as I'm aware
    These may not be rechargeable but we have always used this brand of batteries. They always seem to last the longest out of all the other brands that we have tried. I am glad that we always have these on hand. They are dependable no matter the device that you use these batteries for .
    The Rayovac 815-4TFUSK Fusion AA Advanced Alkaline Batteries - 4/Pack is a great battery when you don't want to be changing the batteries in an electronic device every couple days.
    These Rayovac batteries are great, they last longer than the Panisonic we were buying, and they are a little more money but pay off in the long run.
    These are long lasting batteries. A pack comes with 4 and they are very inexpensive. I like that they are alkaline and this brand makes other sizes
