We’ve all asked ourselves this question at one time or another. But do you know the answer? Let’s take a closer look at rechargeable batteries versus standard alkaline batteries to see just how they measure up.
How are they different from regular alkaline batteries? How do they work?
A rechargeable battery is a battery that can be recharged and used many times. It is also known as a storage battery, as it has the ability to accumulate and store energy. Rechargeable batteries come in many sizes and types. NiMH is a common type, so 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.
Where do my disposable batteries go and are they harmful to the environment?
Unfortunately, the jury is out on this one. Unless you live in California (where recycling of all types of batteries is required due to the potential toxicity of their components), they probably end up in the landfill. If they do get recycled, they will, in all likelihood, get turned into rebar or angle iron.
Are rechargeable batteries really cost effective?
According to one journalist, after just a few charges the rechargeable batteries will pay for themselves! That’s quite a bit of savings – as much as $100 or more each year depending on how many batteries you typically use. If you’ve got kids, digital cameras or a myriad of other things – you probably use a lot.
