Why Use Rechargeable Batteries?

June 18th, 2013 | Posted by EnergyEarth in Ask the Expert

We all know rechargeable batteries are better for the environment. But most of the time, it’s so much easier just to pick up a pack of the least expensive single-use batteries at the corner store when we need them. Did you know that rechargeable batteries cost significantly less overall and have a much lower environmental impact than disposable batteries? While they may cost a bit more initially, these energy saving accessories can be recharged and used hundreds of times, saving you money and helping you stay green with ease.

How do rechargeable batteries work?

Rechargeable batteries come in many sizes and types. Since we carry only rechargeable NiMH batteries, we’ll take a look at how they work specifically.

Rechargeable nickel-metal hydride batteries, or NiMH batteries, work in very much the same way its more common disposable counterpart does. However, NiMH batteries use a combination of nickel oxyhydroxide positive electrodes (NiOOH) and hydrogen-absorbing negative electrodes instead of cadmium or other, more harmful materials. A NiMH battery can have 2-3 times the capacity of cheaper batteries of the same capacity.

Why should you use them?

–          You’ll save money. Like we said, rechargeable batteries may cost more initially, but they can be reused hundreds of times and last for years, costing you significantly less overall.

–          You’ll help protect the environment. All batteries contain corrosive materials and heavy metals, even rechargeable ones. The fewer batteries produced and used, the fewer that get tossed.

–          You’ll conserve natural resources. Because rechargeable batteries can be used over and over, far fewer need to be manufactured.

–          You’ll reduce waste. Since you won’t be throwing away all those single-use batteries, they won’t end up in landfills or fill up your recycle bin nearly as quickly.
