Hey, AO-16 and IO-26 still have some decent batteries, even after 20 years or so :)

Check their orbit numbers (80k-100k), and that's very close to the number of time they have been charged/discharged!  hehe

Neat on the new technology...but our buddies that built those birds picked some good batteries too!
