Hi all,

I usually don't remove the batteries from my calcs because I like to use them regularly. But I put a little adhesive part of a post-it on the back of the calculators and I document by this way the recommended month in mm/yyyy format to remove and change the batteries when it's time to do it.
In an other way, you can established a list of the calcs on paper (smartphone,...) and link each serial numbers or models with a limit remove date of the batteries.

Keep you safe !
