Introduction: Battery Juice Checker

Wanna know if your battery still has enough juice for you to use? Then take a look at this useful battery hack!

Step 1: Bounce Your Used Batteries

Drop the battery down with the flat side down about little less than an inch. If the battery falls its juice is mostly gone and not useful. If the battery stands up straight without falling, the battery is good to use! Try several times with each battery.

This would only work if you discharged your batteries with LARGE wattage --> Creating a pressure inside the battery by generating gases from the overload. This would bulge the battery a bit and causes a less firm stand.
