Lead-acid batteries and Sulphuric acid

Lead-acid batteries needs sulphuric acid; their prices have moved together.

Lead-acid batteries (energy) and Sulphuric acid (chemical): 2 relationships.

How they are linked

1. Material need

Physical flow · Direct · Sulphuric acid → Lead-acid batteries

Building or running Lead-acid batteries needs sulphuric acid.

2. Price link: electrolyte

Cost and price · Moderate · Both ways

Each cell is filled with dilute sulphuric acid, and spent acid is recovered in recycling. Acid is a small cost, so the acid index shows only a weak link, with monthly moves at 0.08 and yearly moves at 0.36.
