I made a "caddy" for my Bosch batteries. Use at your own risk. Works for me. I also have one available for Ingco P20s batteries.

So... apparently it was not very wise of me to use the kitchen funnel to pour some desiccant beads.. lol.. I washed it, put it back in the kitchen cupboard and marched straight to my pc to make my own funnel - and then some.
