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.
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.
Stock car superstars Richard Petty and Bobby Allison depended on DieHard to power their cars at the 32 events scheduled for NASCAR®'s 25th Anniversary Grand National Season in 1973.

The DieHard 48 has twice the life of its competitors because it applies technology that protects it from the inside out. Ordinary batteries crash quicker from spilling and losing electrolytes. They're sensitive to vibration and are slow to recharge. This battery is 20 times more resilient to vibration and recharges twice as fast. AGM technology allows the battery to consume fewer electrolytes and holds on to as many of them as possible. It supplies your car with a lot more charge to keep up with daily demands, and with 250 quality control checks, it out-performs and outlasts the rest.

  • The DieHard 48 Gold AGM Battery is the cream of the DieHard crop
  • It utilizes genuine AGM technology that reduces the consumption of electrolytes, preserves them and gives your engine the power it needs to meet your daily driving demands
  • It recharges much faster than other batteries
  • While other batteries weaken due to vibration, this battery is 20 times more resistant to damage caused by vibration
  • The Spill-proof design protects some of the more sophisticated equipment
  • Internal components receive further security from the Enhanced Electronic Suspension System
  • It ensures the proficient use of internal volume for more power-per-pound through the Flat-Plate AGM design
  • It has twice the life cycle of its counterparts for extended performance
  • It includes more than 250 quality control checks which makes it one of the most durable batteries on the market
  • It is made in the USA
The DieHard Gold Automotive Battery Size 65 has a tough exterior to defend it against damage and protect you from danger.

​

  • The DieHard Battery 65 uses demineralized acid and full-frame calcium-lead alloy grids to stop the battery from losing water

  • The reserve capacity gives your electrical devices 140 minutes to stay on when the car is off. In case of emergency, you'll have more than two hours to drive to a garage or your destination
  • It is designed to resist the loss of electrolytes with plenty of help from the flush manifold vented cover
  • Flame-retardants vents and heat-sealed prevent fires and emission of dangerous vapors during maintenance
  • The carrying handle makes it easily moveable
