As always, our moderator is correct. Some but not all Die Hard and Interstate batteries are made by Johnson Controls. The following is a partial list of batteries made by JC:

Motorcraft®
Sears Die Hard Gold
Auto Zone (Duralast Gold)
Eveready
Everstart (Wal-Mart
Interstate Mega-Tron
Toyota (TrueStart)
Mitsubishi (Diamond Car Care)
Mazda
Advance Auto (Autocraft Titanium)
Costco (Kirkland Signature)
Pep Boys (ProStart & Energizer)
Johnson also makes the Optima brand

The Delco battery that came in my 2001 Tacoma lasted over sever years. The Johnson Controls made battery that came in my '05 Tundra lasted three years. That would not be remarkable except that it was the first of five Toyota OEM batteries that didn't live to the ripe old age of seven years. The other three were Land Cruisers that came with Japanese made batteries.
