What Are the Different Kinds of Batteries?
As technology continues to grow and new products are developed, there's increasing need for batteries to power these many various devices. From phones and cameras to your child's favorite toy, or even grandpa's hearing aid, everyone needs batteries. But not every battery is the same. Not only do they vary in size and voltage, but also in terms of the materials of which they're made.

Size Requirements
* Different gadgets require different levels of voltage. For example, a video camera needs a larger and more powerful battery than your remote control. Many batteries that power larger devices such as phones, laptops and other similar devices can be plugged in and recharged. Smaller devices, meanwhile, usually require you to replace the batteries once they die. Common Types

* Double A, Triple A, C and D batteries are some of the most used types of batteries. Many are alkaline batteries, and once they run out of juice, they're no longer any good. The rechargeable versions of the AA and AAA batteries are made from nickel-metal hydride. While the rechargeable batteries may cost more upfront, in the long run they can save you money. Rechargeable Batteries

Nickel-metal hydride and lithium batteries carry the largest amounts of energy and are usually rechargeable batteries used for laptops, cameras and cell phones. Not only can this type of battery be plugged in and recharged, but it also can hold a charge for longer than "throw-away" batteries. Zinc Air Batteries

* Zinc air batteries use oxygen to produce energy, and therefore they contain less storage space, allowing them to be made very light and small. And while zinc air batteries can't power large devices, they offer a steady flow of energy, making them good for use in hearing aids and other small devices. Silver Oxide

* Silver oxide batteries are similar to others in size. The silver oxide allows them to store more energy. They deliver the same...
