Trying to figure out if a battery has any juice left can be a tricky thing, unless you have a fancy battery with those little finger-meter thingies. They all pretty much look and feel the same, dead or alive. But what if you could tell by doing a simple little test?

The life hack I’m testing claims that you can determine (somewhat) if a batteries is dead or dying, or if it’s still good to go. The test itself seems really simple – they all do, that’s why they are life hacks – and it is. Coming to a conclusion based on the test is a little bit tougher. See for yourself below.

While every battery didn’t exactly react like the hack suggested they would, I did notice a difference between the dead batteries and the new one. So I wouldn’t call this a guaranteed, proven method…I would say you could at least get an idea about the life of your batteries.
