How many times have you stuck batteries into and out of a device to see if they still have any energy left? Most people have that drawer full of junk batteries in their homes. Some are dead, and some of them are still good with plenty of energy left. So how can you tell the difference between the two?
The most accurate way is to use a multimeter. This device measures current in the battery and tells you how much power it’s got left. However, not everybody has this tool. Not to worry. There’s an even simpler way to find out without one. This works for all types of alkaline batteries. The best part is, it only takes 2 seconds. Now you can finally have a way to tell instantly if it’s dead or not.
