Genesis battery (was Space station goes to Plan B for oxygen)

One of the articles I read, said something about overheating a battery
on Genesis just after launch. Possibly during onorbit checkout???
Maybe it was the capsule's battery that they were talking about???

I couldn't tell whether the battery thing was actually a likely cause
for the Genesis parachute problem or just a speculation only because
there happened to be new releases on it.

Here's the information that I saw on the battery:

Soon after Genesis was launched in August 2001, engineers noticed
potential problems with a battery in the probe's sample return
canister. The canister crashed today in the Utah desert when it's
stabilizing parachute failed to deploy. The cause of the mishap is not
yet known and it may have nothing to do with the battery problem noted
early in the mission. But for the record, here is part of a November
15, 2001, news release from the Jet Propulsion Laboratory that
addressed the issue:

Project managers are monitoring the temperature of the battery
inside Genesis' sample return capsule to make sure that
long-term heating does not impair its performance when the
capsule returns to Earth in September 2004. Although the
battery is likely to become hotter than originally expected,
the flight team has a number of options for managing the
battery's temperature, and they do not expect the issue to
affect the mission.

The mission's science requirements call for 22 months of solar
wind particle collection. "In our current plan Genesis will
meet and exceed that goal, collecting up to 26 months' worth
of solar wind particles," said Chet Sasaki, Genesis project
manager at NASA's Jet Propulsion Laboratory, Pasadena, Calif.

The temperature of the lithium-dioxide battery is currently at
23 degrees Celsius (73 degrees Fahrenheit), within the range
anticipated by spacecraft designers. A radiator device
intended to shield the battery is not working as well as
expected, however, and the battery is likely to heat up to 42
degrees Celsius (108 degrees Fahrenheit). Mission managers
consider this temperature to be within acceptable limits. They
note that similar batteries have been maintained at 60 degrees
Celsius (140 degrees Fahrenheit) for 15 months without
impairing their performance. Ground tests are being conducted
on lithium batteries to measure their durability at various
temperatures.

The Genesis project team has been attempting to bake potential
contaminants off the battery's radiator by heating the
area. They are doing this with the spacecraft's sample return
backshell opened just enough to allow gas trapped inside the
capsule to escape, while still avoiding exposure to the Sun.
