Since Lindsay's application was in the southern hemisphere thecurrent
generated during collapsing fields as a by-product of the on/offcycle
would charge the internal battery instead of draining it.  (Sorry,the
preceding is a joke, I was just trying to make the point that Idon't know
the reason for the internal battery failure). 

Lindsay did not mention the frequency with which the Tektronix was 
activated, I assume it was the same sort of interval (about every2 
hours) but if not that would be a significant factor.  

Another possibility would be differences in the 1502B and 1502C in 
terms of their power up requirements and as Lindsay mentioned .

More information without an actual answer.
