G'day everyone :wave:
I've got several battery chargers (panasonic camera battery charger, NiMh AA charger, Ultrafire 18650 / 16340 charger) that simply display a RED light when charging ... and then a GREEN light when finished.
Well, the problem is that some color blind people (I'm red-green color blind) really struggle to tell whether the batteries are charging or finished. This is frustrating and can also be possibly dangerous if batteries are overcharged (depending on the charger).
Here's a simple trick that I discovered to make life easier:
Stick a piece of RED cellophane (that clear thin plastic often used for wrapping up presents) over the charging status lights. The RED charging lights will easily show through the red cellophane, but the GREEN charging will practically be blocked by the cellophane!
Effectively, when I now glance at my charger and see the bright status light I know it is charging ... then when I see that the status light has "disappeared" I know it has finished!
Hope that makes sense. As the typical charger uses RED and GREEN to display charge status, I think that only RED-GREEN color blind people are affected ... but if you also find that you have this trouble sometimes, give this trick a go!
... if you have any spare red colored flashlight filters lying around, you can also use them instead of cellophane ...
Good luck, and safe charging everyone! 🙂
