It seems to be about percentage of the 2017 production. But does it measure value or volume?
Does it include lithium-based batteries? I believe they were only introduced to the market in the 1990s, but the graph goes back to 1975. Also, how many of these batteries are lead-acid based car batteries, disposable batteries for electronics, rechargeable or not, etc.
