Our Heritage

Powering Happy Moments Since 1906


After over 110 years making batteries in Wisconsin, we have more than a few reasons to be passionate about what our
people have accomplished together.

Take a trip through our archives to see the products, places, and people RAYOVAC® has touched throughout the years.


1914

The French Battery Company introduces the French Flasher.

  • Flashlights are so novel at the time publications often refer to them as "electric candles".

  • Battery technology is so poor that consumers flash them on and off to keep them working for any valuable amount of time, yielding RAYOVAC®'s product name.

1933

RAYOVAC®'s Arthur Wengel patents the first portable radio with high fidelity reception.

  • Cumbersome by today's standards, its suitcase style shape draws crowds as its inventors lug it through the streets of New York and Philadelphia.

Wengel's portable plays as clearly today as in 1933.

1937

RAYOVAC®'s Arthur Wengel patents the first wearable vacuum tube hearing aid.

  • Wengel also pioneers scientific methods to test hearing and originates the concept that hearing aids should be fitted to each individual wearer.

  • Wengel releases the patent to the market at large in order to spur investment in the infant technology.

1939

RAYOVAC® introduces the first leak-proof "Sealed in Steel" dry cell battery just 3 months before Hitler's legions invade Poland.

  • The patented, industry-first steel can reduces leakage and provides a much longer lasting battery.

Early leak proof advertising did not trumpet the main advantage of this new battery. During WWII, a "soft sell" approach was used, because nearly all went to the military instead of civilians.

1949

RAYOVAC® introduces the steel Sportsman® flashlight.

  • Designed expressly for campers, hunters, and fisherman, it's triple plated chrome shell and stylish exterior make it a universal favorite.
