Combustion road vehicles and Lead-acid batteries

Energy flows from lead-acid batteries to combustion road vehicles; their prices have moved together.

Combustion road vehicles (energy) and Lead-acid batteries (energy): 2 relationships.

How they are linked

1. Energy flow

Physical flow · 75% of flow · Lead-acid batteries → Combustion road vehicles

Starter batteries crank combustion engines.

• 75% of Lead-acid batteries's energy goes this way

2. Price link: main customer

Cost and price · Weak · Both ways

Every petrol and diesel car needs a starter battery, and the replacement market is large, including in India. The car price proxy shows no link to battery prices, with monthly moves at 0.01, because car prices reflect many other costs.
