Batteries: Rechargeable And Non-rechargeable

By:


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.

The primary, or non-rechargeable, battery is most often used in small, portable devices that do not require a great deal of power. Such devices include radios, toys, and flashlights, to name a few. Convenience is a major selling point of these batteries. They require no preparation, being ready to use upon purchase. In addition to that, primary batteries are generally quite cheap, and offer a high energy density.

Of course, primary batteries are not without their shortcomings. The most severe problem is the waste caused by primary batteries. The average household goes through many primary batteries, resulting in a great deal of waste. When disposed through normal means, some primary batteries (like button batteries) can pollute the environment with corrosive materials and heavy metals. As such, these types of primary batteries can only be disposed of through particular means, which may vary according to the consumer's residence. Batteries can sometimes be recycled, but this is not always an available option.

Secondary, or rechargeable, batteries offer an alternative. These batteries are typically used for electronic items that require more power. Secondary batteries are used for products like phones and power tools. The laptop battery is a common example of this type. As their name suggests, these batteries can be reused. This makes up for the increased cost and decreases wastage.

Secondary batteries also present some drawbacks. One of these is preparation: they often need to be charged before their initial 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. The proper disposal of rechargeable batteries presents another problem. Most secondary batteries are classified as hazardous wastes. Fortunately, they 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. The materials can have a major impact on the use and benefits of a battery.

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.
