For Earth orbit satellites, ensuring reliability and safety requires the DOD of Li-ion batteries to be limited to about 40%.
“For Earth orbit satellites, where long life cycles (>30,000 cycles) are expected [85], ensuring reliability and safety requires the DOD of Li-ion batteries to be limited to about 40% [41].”
From Parametric Study of a Lunar Base Power Systems (2021) · cites this paper as [85]
The Cell Systems passage compares portable fuel cells with lithium-ion batteries, but does not discuss satellite batteries. Searches for Earth-orbit satellites, depth of discharge, and a 40% limit found no passage in our copy addressing the attributed claim. The >30,000-cycle statement has a separate citation and is not judged here. (LLM, conf=0.76)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
