There is a precaution not to keep batteries in medicine containers as the battery may be toxic if mistakenly swallowed. I keep new batteries in the original package in a soft hearing aid case I carry in my pocket. Also in the soft case, I carry a small plastic container where I store partly used batteries. I replace batteries every Monday morning and they're good through the workweek and part of the weekend. Once they die on the weekend, I insert partially used batteries, if any, in the HA until Monday morning when I replace them with new batteries. The weekend backup batteries last for a while even though the tabs have been removed - I'm still figuring out how long. This way, I avoid having to interrupt activities at work to change a battery.
