Lifeline Batteries — 'Made in USA' claim

Lifeline Batteries, based in San Dimas, California, manufactures AGM batteries using absorbent glass mat technology. The company describes its AGM batteries as made in the USA and positions itself as a family-owned and operated producer with roots in the aerospace market. Lifeline traces its origin to founders who began producing lead-acid batteries from the ground up more than three decades ago, then expanded into aviation before marketing brand-named batteries across multiple industries including RV, marine, and racing.
