Editor's Pick: Time to change the batteries in your smoke alarms? 9V block batteries aren't used often, but it's a hassle when you need one and find it dead. The Energizer MAX series has a long shelf life, so stock a few in your drawer. When the alarm's low battery beep goes off, just swap them in.
