In the 1930s, archaeologists unearthed a mysterious clay jar in Iraq. And that’s the story of the first battery…or is it? That confirmed that two metals and a salt solution are necessary to generate an electric current.

The battery started out as a series of wine goblets filled with super salty water into which Volta dropped electrodes. Volta thought the dead frog kicked because its body was a moist conductor between the hook and the scalpel-and he used that hypothesis to build a battery called the voltaic pile.

Galvani was convinced that meant the frog was electrified, but his friend and fellow scientist Alessandro Volta wasn’t so sure.

When the steel scalpel touched the amphibian, its leg twitched.

He and his wife were skinning the amphibian so they could rub its skin and produce static electricity. According to Lucia Rigamonti, PhD, an associate professor in the Department of Civil and Environmental Engineering at Italy’s Polytechnic University of Milan, some NiMH rechargeable batteries today are made with 15 to 20 percent recycled material.The year is 1780, and Italian physician Luigi Galvani has a dead frog attached to a brass hook on the kitchen table. And when you recycle rechargeables, you’ll even be reducing the need to mine the metals required to make them. (If you’ve ever forgotten about the batteries in an old device and opened it up to discover an unpleasant leakage, you can imagine what happens when countless millions of them are put in the ground.)ĭisposing of batteries at dedicated drop-off points (see Call2Recycle and Earth911 to find them) helps keep batteries out of landfills and their toxic components out of the environment. In a landfill, batteries can leak, which means that the metals and other toxic components in them can be absorbed into the soil and contaminate the water supply. When it does, it’s essential that you dispose of it properly. Second, make sure you buy a charger that can accommodate all of the various sizes you’ll be using.Įventually, every battery, whether single-use or rechargeable, will reach the end of its useful life. That means you’ll probably need to buy fewer of them than you do when purchasing single-use batteries. First, rechargeables have a shelf life of about 5 years and can be recharged roughly 500–1,000 times, depending on brand and usage. When shopping for rechargeable batteries, there are a couple of key things to remember. “Regular batteries are designed to hold their charge for extended periods so that they’re ready when you need them to be ready,” Whitehurst says. Single-use batteries are also better for any emergency supplies you may be keeping on hand, like flashlights. Single-use disposable batteries, on the other hand, are better for products that have a low energy pull over a prolonged period of time and are replaced infrequently, such as smoke detectors or your TV’s remote control. While children’s toys tend to be some of the biggest battery hogs, the same applies to devices like wireless computer mice. “You get the economic and environmental benefits of rechargeables a lot faster in high-consumption devices, like the remote control for your kid’s toy car that eats up AA or AAA batteries,” Whitehurst says.

Rechargeable batteries are best suited for something that draws a large amount of power over a short time. The most important thing to consider when choosing between disposable and rechargeable batteries is how you’re going to use them.
