and if iv lost a contact, ill open another put a new 1 in, if i find my lost one ill use that n put the newly opened one in solution in a lil container n cover it in tin foil. can ths weaken it?

You can't use the broken one, if you have a broken one- discard it, even if it costs money to get a new one!

Oh, thanks guys
