Energizer hearing aid batteries are produced and sold by Energizer Holdings Inc., a global consumer goods company that makes hundreds of personal care and household products under various brand names, including Energizer®, Schick®, Playtex® and Banana Boat®, to name just a few. Energizer Holdings has operations in 50 countries and distribution centers in 160 countries. The company prides itself on innovation and beating out its competitors in all market sectors and in enhancing customers' lives.

But Energizer Holdings is one of the world's leaders in the production of dry cell batteries and flashlights, which are marketed under the Energizer brand name. Perhaps unsurprisingly, batteries were the company's first product. Below is a brief history of Energizer Holdings and its innovation in batteries.

Brief History of Energizer Holdings, Inc.

Like many other brand names which started long ago, Energizer Holdings is a conglomerate of various old companies that acquired each other or merged to offer their products.

Energizer makes hearing aid batteriesIn 1896, National Carbon Company, Inc., manufactured the first dry cell battery - the Columbia - that was made commercially available in the United States. Around the same time, in 1898, Conrad Hubert of the American Ever Ready Company invented an "electric hand torch" - popularly known today as the flashlight - which ran on dry cell batteries in unison with a bulb and brass reflector.

In 1913,  National Carbon Company, a unit of Union Carbide & Carbon Corporation, bought American Ever Ready Company and began using the Eveready name for its batteries, calling them Eveready Layerbilt. As the demand for batteries grew in the U.S., so did Union Carbide's profits, as they jumped from selling 12.5 million batteries in 1922 to 303 million batteries in 1926. Electric radios became the standard in the late 1920s, but during World War II, the need for batteries grew again and more innovations were produced that Union Carbide took advantage of, such as the sealed nickel cadmium plate batteries. The company eventually was renamed Eveready and then, in the 2000s, Energizer, as it branched out into new products, was sold and gained brand recognition for its Energizer battery worldwide, due in part to its unique and incredibly popular Energizer Bunny® advertising campaign in the late 1980s.

Hearing Aid Battery History

Quickly following World War II, the company began investing in the development of batteries for hearing aids. In 1947, Union Carbide produced the first ever hearing aid batteries, and in 1955, the company introduced the first Eveready miniature hearing aid batteries. The year 1960 marked the development of a silver oxide system miniature battery, developed by Eveready for use in both watches and hearing aids.

By 1989, Energizer led the industry in its initiatives to protect environmental and human health by creating batteries that were mercury-free. In 1991, these initiatives extended to its hearing aid batteries, which were the first zero mercury hearing aid batteries in the world to be commercially available. The company then introduced the EZ Change® dispenser for hearing aid batteries, which made it easier for people to change their tiny hearing aid batteries because users could use the device to directly insert the new batteries into the hearing aids.

Hearing Aid Battery Options Today

Today, energizer makes hearing aid batteries in sizes 312, 10, 13 and 675. All of the batteries are mercury-free, come in 100 percent recyclable packaging and are enclosed in an EZ Turn & Lock case that allows you to keep unused batteries secure so they aren't lost. There's an access tab on the back of the packaging to allow easy removal, and the tabs are longer, making insertion into the hearing aid easier. Sizes 10, 13 and 312 are sold in an eight-pack, while size 675 comes in a six-pack. The packaging is also nice because it allows you to tear off the excess packaging on a perforated line so the case fits in your pocket or purse for on-the-go battery changing.

What sets them apart

As a company, Energizer Holdings has made a commitment to sustainability:

"Essentially, our approach to sustainability all boils down to one simple thought: 'Do the right thing.' Not just because we're decent, good-hearted folks – which we are – but because we're staunch believers in the idea that doing the right thing affords us tremendous opportunity to make a positive impact on the well-being of our communities, our environment, and our shareholders."
