Does 9V damage the HP37E?
Message #1 Posted by Tom (UK) on 11 Mar 2002, 1:04 p.m.

Take a look at:

http://cgi.ebay.co.uk/aw-cgi/eBayISAPI.dll?MfcISAPICommand=ViewItem&item=2007198517

Did the buyer get a bargain? Or has the calculator been damaged?

I see wlodekmj bid on this calculator, one in the same :^) (I try not to bid against this guy)

A recent HP11C went for 142 pounds ($200), nice looking but no manual, case, box etc. Are UK buyers starved of decent HP calcs?

My guess is that between the condition of the particular battery and the heavy load of an LED calculator, the battery voltage is very low. I'm not sure what the spec is, but I think a 9V rectangular batttery is expected to provide about 20 ma for a reasonable time. I sure wouldn"t try it!

Thanks to Tom(UK) for some interesting comments. Agreed, a 9V battery does not do an HP_37E much good - I wonder if the seller intentionally used a high voltage to get the apparently very bright display shown in the photograph. That would be very unwise!

I'm honoured that you "try not to bid against" me, but don't deny yourself items you need for your collection :-) Since you are in the UK, maybe we could compare collections one day. That is one of the uses of user groups - to let enthusiasts meet other than here :-) HPCC (www.hpcc.org) welcomes newcomers!

UK prices on eBay reflect the fact that purchasing from the US requires extra payment for postage, plus customs duty, plus VAT, plus paying the Post Office fee for their work in collecting the taxes from us! All that combined means it is easily worth paying an extra 10-20% more to buy in the UK. See my book :-)

I hope the final buyers of the 11C and 37E are happy! Or buy at MoHPC!

I have purchased numerous items from Europe (including a 9100A) and have never been charged a customs duty.
