East Penn has the largest battery manufacturing plant in America. They produce Deka, MK, O'Rielly's SuperStart (unless the model number ends in with a "J"), Sam's Club Duracell, as well as others.

Odyessy, also produces excellent American-made batteries. Odyssey Marine Batteries

Lifeline batteries are expensive and excellent. https://www.impactbattery.com/brands/lifeline/


***Johnson Controls make (Die-Hard, Interstate, EverStart, DuraLast, Exide, as well as many others). Since 2010 the majority of their batteries are produced in Mexico, ​NOT THE UNITED STATES. U.S. law requires that they label all the batteries made in Mexico.

Like with some other products now days, just buying by the label name, that meant quality in the past, does not mean today's quality is the same.
We also have Superlex premium batteries, they are built here in Kentucky. I work there, and can say over the years there have been a lot of improvements made in battery technology.
