Answer:
The government could impose heavy tariffs on all imported batteries.
Step-by-step explanation:
Import tariffs are taxes imposed on imported commodities. Should the government impose heavy tariffs on the imported batteries, their prices in the domestic market will go up.
One of the objectives of a tariff is to protect locally produced goods from unfair competition by low-priced imports. The imposed tax become a cost to the imported batteries, which will make them more expensive. The locally produced batteries will compete favorably with the imports. The domestic industry will grow since it has raw materials and a market to sell its products.
