Problems with 34C Message #1 Posted by Ed Austin on 20 Oct 2008, 11:53 p.m.
Hi there
I purchased a HP34C from ebay and the listing stated "battery terminal has corrosion" but I took a chance (cost me $125 with case but with no charger and no battery pack here in the UK).
I inserted two AA Alkalines and great... the calculator works and passes self test and retains memory.
However the contacts on the battery pack were pretty messy but I managed to scrape off most of the residue which seemed to work its way also inside the calculator.
My question is? Will the remaining residue cause a problem in the future, some of it is inside and therefore I haven't been able to clean it (but can see it through the charging port).
The calculator also has a small crack near one of the screws... I assume this is due to the "slight" stretch when using alkalines?
Thanks for any advice!
According to the serial number it is a week 45 and year 1979 model.
I think it is the "solderless" design.
