Where are energizer batteries made?

Energizer's, Duracell's, Rayovac's, & most Radio Shack & CVS Pharmacy brand are made in the USA. The CVS Pharmacy brand are made to look like Duracell's, and they were made in the USA leading me to believe they could be made by same, they have the same heft to them unlike some of the lower-priced brands. Walgreen's, Sony, are Indonesia, Sunbeam & AC Delco are China.
Some made in USA. Some Singapore and Japan. Barely any are made in China
