Was watching some of the online feed from NASA on the ISS and think it's nice they have a Russian to English translator when the Russian cosmonauts are communicating.
I was wondering, it was said in the "early" days nickel-hydrogen batteries were used on the ISS when orbiting the "dark side" of the earth and then I guess resupply missions brought up lithium ion ones. Probably the nickel-hydrogen ones were sent to burn up in some re-entry vehicle after replacement?
I remember reading where it's advantageous to just charge up lithium ion batteries to 80% capacity to preserve the longest life for long term use.
For some of my small R/C helicopters, I don't care. Charge to 100%, fly the heck out of them and when they crap out, they're cheap enough to buy new packs!
Wonder how NASA and the Russian space agency handles Lithium Ion battery charging on the ISS and if the current cells reach end of life, is that the end of the station? Or are they constantly flying up new packs with the resupply missions to keep the storage capacity up to spec? Ditch the old cells in space to re-enter and burn up? I don't know, but inquiring minds are interested!!! Kurt
