    Types and Designs

    There are dozens of different sizes and shapes; from tiny wafer-type watch and hearing aid batteries to huge shipboard and utility system batteries, there’s a battery for just about any power need. Coupled with the multitude of sizes, there are also a wide variety of chemicals used to make batteries, such as Nickel-Metal Hydride, Lithium-ion, lead-acid, and many others. You’ll read all about the various chemicals that batteries are made with. You’ll discover how the various chemicals and compounds the battery is made of work together to cause it to produce an electrical voltage, and you’ll also be given information on some of the many different ways that batteries are used, from cell phones and laptops, to uninterruptible power supplies for buildings and power utilities.

    About Rechargeable Batteries

    Rechargeable batteries are unique in that when they go dead, you can, with the right equipment, induce a complete new charge into them, allowing you to use them again. Some rechargeable batteries, such as car batteries, allow for the battery to be discharged and recharged thousands of times over the lifetime of the battery. Batteries for personal electronic devices, such as MP3 players, digital cameras, cell phones, flashlights, and portable stereos, can normally be recharged as many as one thousand times. You’ll find information on how to care for rechargeable batteries and extend their usable life. You’ll also find some information on how rechargeable batteries are rechargeable. Wondering why your rechargeable batteries aren’t holding a charge for as long as they should? You’ll read some useful troubleshooting tips so that you can have a chance to regain some of that usable life back.

    Special Considerations in Marine Battery Applications

    Batteries have been used in ships for a quite a long time. The original submarines that weren’t human-powered were powered by batteries. However, these early batteries had a major drawback that sometimes proved fatal to the sub’s crew: Exposure of the batteries to salt water, even in small quantities, caused the generation of deadly chlorine gas. Marine battery technology has evolved over the years. Referenced below you’ll find lists of battery types that are in use in marine applications as well as information on how these batteries are maintained aboard ship. Anchors Aweigh, matey!

    Responsible Battery Recycling

    Environmental responsibility is high on many peoples’ lists these days. The chemicals used in batteries, whether they’re regular alkaline batteries or one of the many varieties of rechargeable batteries, can cause severe problems to ground water sources and the ground in and around where they’re improperly disposed of. Referenced below you’ll find a wealth of information regarding the process by which batteries are recycled as well as information on how you can responsibly recycle your used batteries when you’re through with them.
