Comment (by Quozl):

 Richard Smith asked for battery voltages again, in case the batteries were
 at fault.  Tests done just now:
  1. measured voltages of each battery open circuit, results were 6.80V,
 6.81V and 6.76V,
  1. inserted each battery into laptop, powered up laptop, with AC adaptors
 disconnected,
  1. recorded psu_0/capacity, results were 94%, 94%, and 94%,
  1. recorded psu_0/voltage, results were 6500, 6546, and 6474,
  1. noted that temp2 is showing 50000,
  1. noted that voltage and capacity decline as expected.

 My conclusion is that the batteries are not at fault, but rather the EC or
 other components enter a non-functioning mode as a result of being left
 idle.
