Rechargeable Batteries Vs Disposable

Rechargeable or disposable batteries are both good choices and will reliably energize the batteries we depend on. Read on to learn how to make the best choice between rechargeable and disposable batteries.

Disposable batteries are largely used for powering low voltage devices that are not used often. The life and endurance of the disposable battery is dependent on the apparatus it will energize and the chemical agent involved in the makeup of the battery. Carbon Zinc is the most affordable and best-selling battery and is available in all of the standard sizes. The sizes include AAA, AA, C, D, and the 9-volt as well as lantern batteries in 6 and 12 -volt. Carbon Zinc works best in low energy depleting devices used now and then. Longer lasting but more costly is the heavy-duty carbon-zinc battery which functions well in low and medium drain appliances that have low usage. Others include Alkaline, Super Alkaline, Air Alkaline, Lithium, Silver Oxide, and Zinc Air.

Alkaline Disposable Batteries

One of the favorite batteries is the alkaline and it has all of the (standard) sizes available. The alkaline battery includes the flat round type that works well in often-used medium to high energy depleting items. For devices such as medical apparatus and photo equipment, a (specialized product) in the alkaline line is available. (Super alkaline) batteries will last longer in high use devices. The less common (air alkaline) batteries are very long lasting however are mostly used in large lantern types as in 6-volt and 12-volt.

Rechargeable Batteries

(Ni-Cads) or nickel cadmium is the most commonly purchased rechargeable battery. The energy provided by these batteries is adequate however; the disposal is more hazardous to the environment because of toxic metals. The best rechargeable batteries are (NiMH) or nickel metal hydride. They perform well and are less toxic to the environment. Rechargeable batteries are accessible in quite a few sizes and voltages. There are choices of all of the more typical battery sizes as found in disposable, as well as specialty sizes. Rechargeable alkaline batteries can replace the disposable batteries normally used, are less costly than the (Ni-Cad), and hold a longer charge, however; the life span is less than NiMH batteries.



As a general rule, rechargeable batteries will save money. This is especially true with items used frequently such as toys and electronic gizmos. The initial expenditure for the rechargeable batteries and charging unit will be more expensive. However, if you change batteries routinely on heavily used devices that pull a lot of energy and if you find yourself making too many trips to the store for disposable batteries then do the math and approximate a yearly cost. If the price tag seems high then contemplate the advantages of the rechargeable battery. The range in price for rechargeable batteries and the recharger may be around $75.

Consequently, if rechargeable batteries make good sense for your particular use, then consider purchasing extra batteries. When the power runs out of the Walkman while jogging and you don't want to wait to charge the battery and the kids are having a fit because their favorite toy is out of power. This may be the time to purchase extra rechargeable batteries. The additional batteries can be charged and conveniently waiting for quick replacement.

In conclusion and without having to do jump through the hoop with mathematical equations, the question of rechargeable versus disposable batteries boils down to usage and cost. How often are the devices used and how much energy do they consume? Low wattage clocks and remote controls or flashlights, and rarely used items, will of course be a better choice for disposable batteries because they will last for at least a few months. On the other hand toys and radios and similar appliances used often and consume a lot of energy would most likely be the best candidates for rechargeable batteries and would after the initial investment save money. The cost per kilowatt-hour is much higher in disposable batteries. In both cases, consider the environment while using batteries. Many retail stores will accept used batteries and provide for proper and safe disposal, to keep our earth as safe and healthy as possible.
