The Manufacturing Process: Behind the Scenes at Johnson Controls Facilities

Raw Materials: Insight into the components used in DieHard batteries

When it comes to crafting DieHard batteries, Johnson Controls demonstrates an unwavering commitment to quality by carefully selecting the raw materials used in their production. The primary component of these batteries is lead, which is sourced from reputable suppliers known for their high purity levels. Additionally, a mixture of metal alloys, including antimony and calcium, is incorporated to enhance battery performance and longevity.

These alloys contribute to minimizing self-discharge rates and improving overall power output. Furthermore, specialized separators made from microfiber materials are utilized to prevent internal short circuits and ensure optimal charge transfer.

Production Stages: Step-by-step breakdown of how batteries are manufactured

The production of DieHard batteries involves a meticulously orchestrated series of stages designed to achieve peak performance. The process commences with grid casting, where lead alloys are cast into precise grid patterns that act as conductive pathways within the battery.

These grids serve as supports for active material application during subsequent steps. Next comes pasting, during which a precisely formulated paste consisting of lead oxide and other additives is applied onto the grids using advanced machinery.

This step ensures uniform distribution and adherence of active material throughout the battery plates. Once pasting is complete, plates are cured through controlled drying processes that promote stable chemical reactions necessary for proper functioning.

Following curing, assembly takes place whereby positive and negative plates are interleaved with separators to form the battery’s core structure. Once assembled, these cores undergo envelope formation through immersing them in electrolyte solutions—typically sulfuric acid mixed with deionized water—to activate electrochemical processes within the battery.

After envelope formation, heat sealing seals off cells securely before final integration into finished battery casings. Further quality checks verify correct cell voltage levels and ensure optimal acid levels, resulting in DieHard batteries ready to power a variety of applications reliably.


In the world of battery manufacturing, Johnson Controls emerges as an unrivaled force behind the creation of DieHard batteries.
