Text version of the map
- Duralast Batteries (Brand): Duralast is AutoZone’s battery brand, and Clarios is a documented manufacturer; Clarios’ public filing does not establish one factory or exclusive supplier for every Duralast battery. [1][2]
- Duralast Batteries → AutoZone (Owner): AutoZone’s in-house Duralast brand. [1]
- AutoZone → Duralast Batteries manufacturing (Manufacturer): Clarios is explicitly identified as supplying Duralast through AutoZone in its December 2023 filing. [2]
Who owns Duralast Batteries?
AutoZone’s annual report identifies Duralast within its exclusive in-house brand range. AutoZone is the retailer and brand business; that does not make an AutoZone store the manufacturer of a battery. [1]
Who actually makes Duralast Batteries products?
Clarios’ December 2023 filing names Duralast through AutoZone among private-label relationships. This is primary manufacturer disclosure, but it does not identify the supplier of every current Duralast group size. [2]
Where are Duralast Batteries products made?
The public filing describes a worldwide battery business rather than a product-by-product factory directory. Exact Duralast plant and country assignments remain Unconfirmed here; no East Penn or other maker is assigned to a specific unit without dated product evidence. [2]
Is Duralast Batteries made in China or the USA?
The Duralast label and a US retail sale do not establish US manufacturing. The reviewed dated documents also do not establish Chinese origin for every battery in the line. [1][2]
Same factory, different label
Clarios also supplies DieHard according to the 2022 AGM announcement. That confirms a common manufacturer for documented relationships, not identical chemistry, specifications, warranties or assembly lines across all DieHard and Duralast products. [3][2]
