Batteries rechargeable or nonrechargeable

Batteries: Rechargeable or Non-Rechargeable?

When it comes to batteries, consumers can buy either non-rechargeable or rechargeable ones. These are also called primary and secondary batteries, respectively, and both are useful for different situations.

Primary (non-rechargeable) batteries are often used to power small, portable devices. Radios, toys, and flashlights are all devices that use primary batteries. Convenience is a major selling point of these batteries. These batteries can be used from the moment of purchase. Another advantage of primary batteries is that they are usually cheap, and have a high energy density.

Of course, primary batteries are not without their shortcomings. The worst problem associated with primary batteries is the waste they can create when improperly disposed. Because the average household goes through so many, it is easy for waste to accumulate. Some primary batteries, like button batteries, can pollute the environment if disposed through normal means. These primary batteries require special means of disposal, the nature of which varies from place to place. Batteries can sometimes be recycled, but this is not always an available option.

Secondary batteries, also known as rechargeable batteries, provide an alternate option. Secondary batteries are often used for electronic items that demand more power. Secondary batteries are used for products like phones and power tools. The laptop battery is a common example of this type. As suggested by their name, these batteries can be used multiple times. This makes up for the increased cost and decreases wastage.

Secondary batteries also suffer from some drawbacks. One of these is preparation: they often need charging, even before the first use. Lack of versatility is another problem. While a primary battery can often be used with a wide range of products, secondary batteries are rarely interchangeable. Disposal of rechargeable batteries is also problematic. Secondary batteries are usually classified as hazardous wastes. The good news is that secondary batteries last much longer than primary batteries.

Many different components go into the manufacture of batteries. These materials aren’t necessarily exclusive to one type of battery. Alkaline batteries are an example of this, as they are usually associated with primary batteries, but are sometimes used as secondary batteries. A battery’s component materials play a big role in determining how it’s used.

Primary and secondary batteries both play important roles. Because of this, battery outlets usually carry both varieties. Many people now choose to buy from online battery retailers, which offer a wide variety at a low price.
