We tend to throw away batteries without a full juice before they actually die. This new D-type battery design, mostly used in Flashlights / Torch can accommodate such AA and AAA batteries to get the most out of them.
This new product called R Battery is designed by Wang Shuo. Though it’s limited due to overall D-type battery has dropped down significantly over the years, this design looks promising up to an extent. You also may like to read about different Battery Sizes
What is R Battery?
When we say – the batteries have died, there still remains some power inside them. Which means, we throw the glass away while juice is not finished completely. This new R Battery design is made in such a way that – it’s in a shape on a D-type battery and can hold double A or triple A batteries inside.. To collaborate & transform remaining power from these old used batteries.
The Power of Three
R Battery has three slots to hold AA and AAA batteries that are past their prime and into the graveyard. Near-dead batteries do have some charge in them and the good ole’ R here uses their juice to spike up as one big cell. I’m not sure of the dimensions of this new big battery, but I see where this project is going and with a few revisions, I’m sure it will be a winner.
How does it work?
See, you can find three holes as you open-up the R-Battery cover… specifically created to hold AA and AAA batteries. Place these old batteries and the device will collect remaining power once the lid is closed to connect them together.
The LED strip on the side of this R-Battery then can display the amount of power collected from all three inserted used batteries.
I am not sure how & when this will go into production, but I just loved the concept of re-using old dried batteries. Isn’t it wonderful! Have you seen any product in the market yet? Do share with us through comments.
