Unfortunately I now rarely use my lovely HP-17B II business calculator because the batteries get drained too quickly and as they are cell button lithiums they are too expensive to keep replacing them all the time.
Anyone else noticed this with the 17B II ? I suspect this is normal due to the inbuilt clock and alarm system of the 17BII but I could be wrong. Any suggestions other than keeping batteries out of the unit are appreciated.
