India, Sept. 30 -- Mobile networks never get a day off. When the grid flickers, the tower still has to stay lit, and that job has traditionally fallen to diesel generators and lead-acid batteries. Telecom companies are now moving towards lithium-based storage that is cleaner, lasts longer and needs less upkeep. That shift is creating steady demand for battery makers who can supply at scale and build within India.
