Re: battery test for the HP15c Limited Edition Message #4 Posted by Jeff O. on 3 Jan 2013, 8:17 a.m., in response to message #1 by Guido (Canada)
Thanks for the tip!
Unfortunately, during my 15c LE battery capacity experiment, I found that the memory often got cleared during battery changeover, even when changed one at a time. I also found that at 2.7 Volts, there was a lot of life left in the batteries. They hit 2.7 Volts very quickly, then held fairly steady for a long time. But when the unit finally quit during a run of the test program, the batteries read 2.6 Volts. So picking the optimum time to change may be tricky, and the act of changing may clear memory anyway.
Of course my voltage test procedure of moving the batteries to a 34s and using the BATT function was not the best. I wish I had known your trick when I did my test. I may do some experimentation using your technique to see how that compares to the wp34s method.
