Colibri lighter you bought in 1983or 1984 touch sensor you need a battery where can you buy one?

I just called the service department of the new CST Enterprises that owns Colibri lighters brand (401) 943-1500 and was advise if you are looking for a compatible battery to replace the CR 1240E which was discontinued, you can stack two easily found 386 button cell batteries in the battery compartment and that will work. I'm going to try tonight to see if I can bring my father-in-laws beautiful vintage sensor lighter back to life. If you are looking for a replacement for another battery type, their service department was very helpful and had an immediate answer for my inquiry.
