[amsat-bb] Ni-Cd Batteries on Satellites

[Pedro Converso]

LO-19 (aka LUSAT) after 30 years in space is emitting day and night a
strong carrier.

What is amazing that after over 2 millions charge/discharge cycles its
vintage NI-CD batteries are still able to receive and hold charge.

It is known that Lithium based batteries usually halve charge capacity
after +/- 400 cycles, probably you noticed that on your portable
device. https://batteryuniversity.com/_img/content/lithium2.jpg

This is just a comment for future satellite plans if long duration is
part of the objective.
