Rechargeable batteries

With the increase of portable devices such as laptops, cell phones, MP3 players and target = "_blank" title = "Battery power tools"> cordless power tools, the need for rechargeable batteries has grown substantially in recent years. The concept of the rechargeable battery has been around since 1859, when the French physicist Gaston Plante invented the cell Lead-acid, which later became the world's first rechargeable battery. That same chemistry is still used in car battery today.

The basic idea behind the battery the battery is simple: when electrical power is applied to the battery, electrons flow from negative to positive occurs during discharge is reversed and restored energy. This requires an adapter current in the case of devices with a function of the batteries or nickel-cadmium batteries or standard nickel-metal hydride, the multi most common use rechargeable batteries used today in remote control, flashlight or a digital camera.

Car batteries are one of the oldest type of rechargeable batteries and, in fact, the electric car predated the gasoline cousin. In a standard car, there is a single SLI lead acid battery that supplies power to the starter motor, lights and ignition system. The charger battery, in this case is the alternator, a smart device that converts the energy of gasoline into electricity and distributed as needed. In the electric and hybrid cars, batteries are used to drive the vehicle on the road. Traction batteries come in many varieties, from lead acid, nickel cadmium, nickel metal hydride and lithium ion.

The recharge rate has increased substantially in recent years and is divided into three categories:

Slow: 14-16 hours
Fast: 3-6 hours
Fast: Less than an hour

The loading rate is determined by the amount of electrical current is allowed in the battery charger. Some batteries can handle more tension in an amount less of time without overheating, while others need a lower voltage for a long period of time. The faster the rate of charge, more More likely is cargo that could ruin the chance of a battery of holding office. The key to avoiding a burden is the ability to dissipate load power once the maximum current is reached. Most chargers have built-in voltage regulators that, which allows you to leave your phone safely phone or a computer plugged in overnight.

The speed and efficiency of loading depends greatly on the quality charger with it. Chargers vary in performance Based on the price and like most products you get what you pay for. Chargers are generally designed for specific cell chemistry, although newest universal chargers have built in sensors that identify the cell type and react appropriately. There are also chargers smart using a microprocessor to monitor temperature, voltage and charge status, which is the percentage of energy available in Compared to its full capacity.

A common problem in nickel-cadmium rechargeable batteries is something known as the memory effect. This is when the battery is continually recharged before it has been downloaded more than 50 percent of its power, making it essentially forget to fully comply with the principle. Memory effect is caused by the formation of difficult to dissolve the crystals of cadmium in the depths of the battery. Cadmium crystals are an inevitable byproduct of discharge, the trick is to keep them small enough to be reformed as cadmium during the loading process. When a battery is completely discharged, the crystals in Deep in the battery is not affected by the flow of electric current, so they are not reformed as cadmium and can grow in the problems of larger crystals cadmium. The battery will still function normally, but is at a maximum at 50 percent. The memory effect can totally avoid cycling the battery once every two to three weeks, letting it discharge completely, and reloading.

It is important to remember that no batteries, rechargeable or not, it will last forever. All batteries suffer from aging of cells and the time they are used, the less capacity that ultimately will. Rechargeable batteries are still a great way to save money and reduce waste.
