Smiley Battery

Discipline: Professional Concept

Discipline: Professional Concept

[Visual / Tactile Distinction]
The plus terminal shows + in shape, and the minus side is - in shape. You can see it to recognize the ± ends. The plus side of battery is convex, and the minus side is concave. When a battery holder is designed for this battery, there is no risk of improper insertion of a battery anymore because of its obvious shape. With the simple but very clear concepts above, this sensational battery makes it easy to recognize the correct side for the plus and minus terminals. Regardless whether you can see or not, whether you have glasses or even reading glasses – absolutely EVERYONE can set the battery correctly without thinking.
