The short lived battery was on Pathfinder, not on the Sojourner rover.
If I recall correctly, Pathfinder had both a rechargeable and a
non-rechargeable battery. It was when the non-rechargeable battery died
when the extended mission ended, because the rechargeable battery alone
was not enough to power the communications gear. The non-rechargeable
battery was designed to last for a month and actually lasted almost
three months.
Anyone can confirm this?
