Ray-O-Vac R9VL8 Lithium Batteries - 9V

Used these to replace the batteries in my smoke detectors. The previous batteries only lasted 6 months, these last the entire year and still hold a charge. I swap them out every year with fresh batteries, and use the rest of the charge for other uses. So definitely worth every penny.

Always reliable in the 9 volt size. This is used for my husband's recliner so very important if the power goes out. Which it did. A lot. Hurricanes!
