[RE-wrenches] cleaning battery caps

Jay,

We sell quite a few of the Water Misers due to the number of mobile customers leaving their RV stored here in the desert for 6 months. They have been effective for reducing water loss. I have seen some real nasty ones but never has anyone suggest any problem with effectiveness. 

The caps are simply a mechanical method of returning H2O to the cells. As long as you can hear the beads rattle, my guess is they will still work. Curiosity got the best of me so I cut open a used one that was no longer rattling. The beads look good but were sticky. If you have some that do not rattle, I would not hesitate to try cleaning them with some strong detergent and thoroughly rinsing.
 
One other thing to check is that the holes are not plugged and they are snapped down tight. Check the inner seal for debris.

Yea weird.

I've got a client who wants to clean his water miser battery caps, they are filled with battery "scum"

He thinks and seems right to me that they are not working as well as they used to, and
I dont know what to tell him

Any ideas?
