Please can somebody advise whether batteries should generally be removed from Pioneer and Voyager HPs if the calculators are to be stored for long periods of time?
Over the past 2 years I have bought some new-in-box HP calculators to keep stored away as future backups. These are an H14B, HP32S, HP42S, HP19BII and an HP11C.
I have removed the batteries as a precaution in case the batteries do leak, but I have heard that it might be prudent to actually leave the calculators stored with batteries inserted to provide nominal power to the calculator circuitry and capacitors.
Please can anybody advise on the pros and cons?
Thanks
