I have a Casio calculator (fx-100s) that still goes strong on its original battery since I bought it, 18 years ago! I use it a few times every week.

- batmansbelt 12y agoIt might be solar powered.
- andmarios 12y agoNo, it only has an AA battery. I also have a remote control from a Sharp radio system which still works after 24 years with its original batteries! But this one is used very rarely, say 2-3 times every year.
- logicallee 12y agomaybe someone else uses it too and replaced the aa battery? Maybe you replaced it but don't remember?
- andmarios 12y agoNo because they both have these japanese batteries that most japanese electronics come with but you can't find them anywhere in the stores. If someone had replaced them, it would be with a known brand. Besides the calculator is always on my home office and I live alone. I was very surprised too when I found out about a year ago.
- lisper 12y agoHeh, I have a Casio EL-5813 that I got in 1980 that still is still running on its original batteries!
