Since reading is probably not an option for batteries, I use a strip of
tape around the batteries for those which can be recharged. Of course,
someone might need to help sort through batteries which have already
been used, to make sure only the rechargeables get the tape. I would
recommend transparent tape, as some products have a very small tolerence
for anything thicker than that. In other words, if one were to use duct
tape, and tried to put two batteries into something, either the tape
would be so thick the batteries would not go in, or, they might go in,
but would need to be pried from the device because they were in too
tightly. This is a method I have been using for a number of years and
have found it works quite well. The important thing is to make sure you
put the tape on at the beginning.
