Value, 100 equals 2017 production. Actual figures [1].
> Does it include lithium-based batteries?
Yes [2]. Chemistry agnostic.
Note, however, that in 2017 “storage battery manufacturing (NAICS 335911) and primary battery manufacturing (NAICS 335912), were combined into a single 2022 NAICS category: battery manufacturing (NAICS 335910).” So comparing across that isn’t straightforward.

Are you sure that's the data set being used in this graph? Taking 2022's value over 2017's anchored value seems to come out to a ratio far higher than any part of this graph shows for 2022. The description text also says it measures indexed real output and other graphs don't beat around the bush about being value based https://fred.stlouisfed.org/series/A35DVS
