Hi Jason,
Thanks for your reply, I grew up with these type of batteries, I always thought these where world wide known, it's only recently that I found out that this is a typical European model of battery.
We use to cut them open when I was a child, when the where worn off, to see what's inside.
This was before we heard of health and safety
all we saw was this was a hard outer case with 3 AA type of batteries in them, connected in series…
