It took nine years of intense research and more than one million dollars for Sears to develop the DieHard — America's most innovative automotive battery — tested, proven and guaranteed to deliver across any circumstance.
Introduced in 1967, Sears designed the DieHard to produce 35 percent more usable starting power than other similar batteries. Featuring a revolutionary tough, thin-walled case of translucent polypropylene plastic, which was 50 percent thinner than conventional black rubber-type battery enclosures, the design's extra room meant bigger plates, more acid and extra starting power.
In addition to the space-saving and visibility advantages, the polypropylene case was stronger as well. The development of tools to manufacture the clear plastic container was a major undertaking. That project alone took some of the country's finest toolmakers more than a year and a half to build. The machines they developed represented a substantial advance in precision injection molding. The first, mammoth injection molding press for the DieHard weighed 600 tons and required 500 metric tons to clamp shut. By itself, the mold for the container weighed 4.5 tons.
Sears revolutionized the automotive battery replacement category in 1967 with the introduction of DieHard — a tough, thin-walled, translucent plastic case 50 percent thinner than conventional black, rubber-type battery enclosures. The result: bigger plates, more acid and extra starting power.
The name DieHard is derived from its unfailing operation over several million miles on test vehicles at high and low speeds in varying climates at high and low altitudes.
During testing, not a single failure was reported in over 26,000 starts in temperatures ranging from sub-zero to more than 100 degrees.
DieHard batteries were used in sets of three to provide the 36-volt starting power for most of the 33 cars entered in the 1970 Indianapolis 500.

In the 1960s, popular TV comedy shows starring Garry Moore, Carol Burnett and Tim Conway all featured parodies of the DieHard brand and its battery known for reliable starting power, performance and long life.
By 1983, Sears had introduced new DieHard diesel batteries for model VWs and Porsches, a new line of fleet service batteries and golf cart batteries, as well as the first DieHard motorcycle battery. Tough enough for select Harley-Davidson motorcycles, the new 12-volt motorcycle battery featured a spill-proof, high-impact polystyrene black case and an ABS plastic top. It not only boasted more power, but greater cold-cranking amps and reserve capacity than many original-equipment batteries.
Then the DieHard Incredicell System arrived. A powerful new automotive battery that virtually did everything except install itself, the Incredicell System featured up to 670 cold-cranking amps and 130 minutes of reserve capacity, as well as an exclusive under-dash-mounted electronic monitor, which kept the motorist abreast of the operating condition of both the battery and charging system. Used in most domestic and imported cars and trucks, the Incredicell System marked a new success for the DieHard brand.
DieHard introduced five new maintenance-free, "add-no-water" 12-volt batteries in 1976 for cars and trucks — eliminating the need for motorists to purchase a more costly premium battery.

In celebration of the 20th anniversary of the DieHard, Sears introduced the innovative XDH-1 Battery. The XDH-1 was a high-performance, experimental battery that DieHard especially made for electric vehicles. During a rigorous testing process, the XDH-1 successfully powered a two-person electric car for nearly a hundred miles at an average speed of 45 mph. With this revolutionary achievement, the XDH-1 DieHard made a serious contribution to the advancement of electric vehicle development.
The DieHard brand continued to lead the automotive battery category, constantly working to develop the most technologically advanced batteries available on the market.
