How To Distinguish Between An Old Or New Small Battery?

Because small battery volume is relatively small, it’s not very convenient to keep, many people like to use a container to put the old and new small batteries together. The result is placed for a period of time. It is not easy to distinguish which battery is new, which is the old battery. Here we introduce how to identify the old or new small battery?

Pick up a small battery in one hand, then place both hands in a parallel position and make sure that the two small batteries are the same height:

Release both hands at the same time and let the two small batteries fall onto the table at the same time. Observe the drop test and you will find that one small battery will bounce very high when it falls on the table, while the other small battery will hardly jump after falling on the table.

The small battery that jumps high is the old small battery, and the one that hardly jumps is the new small battery. The reason why the two small batteries fall to the table after the bounce height is different, this is because the new battery has a semi-liquid material, falling down when a certain buffer effected, which the jump is not high. Because the electricity is consumed, it slowly becomes a solid, so the old small battery bounces higher and higher.

This is the simple way to distinguish old or new small batteries. Quickly use this method to distinguish you from keeping a small battery at home, to see which is new, which is old?
