Battery Improved / Battery

It is very common and necessary using batteries in daily lives. The old way of disassembling batteries wasn’t suit the ergonomics.—We disassemble batteries with a little space.
Because of this, giving me an idea of designing one side of the battery into cone. Push the conical side when we want to change the batteries, the other side will be raised upward, and we can take the batteries easily. The design is simple and easy, there’s no need to explain too much about the usage. It’s easier and more convenient than the old products in the past.
