Editor's Pick: If you have little ones at home, it's worth being extra careful about how you store coin batteries. These batteries feature a three-layer protective design: the packaging is difficult for children to open, and the battery surface has a bitter coating. If one ends up in a child's mouth, the coating turns blue upon contact with saliva, alerting parents to act quickly. Beyond the safety design, these batteries deliver stable power in both cold and hot conditions, and work in car keys, bathroom scales, remote controls, and more. They hold their charge for up to 12 years in storage.
