What are storage batteries?

storage batteries, also known as rechargeable batteries or secondary cells, are objects that store energy until it is needed to power the electronic device. In general, they have similar sizes and voltage to one -off batteries, which are also called primary cells. Unlike primary cells, storage batteries can be launched and then charged, allowing repeated use. This provides a number of benefits to users, especially in terms of financial and environmental effects. Compared to primary cells, however, they have some disadvantages and therefore storage batteries did not receive disposable batteries.

All batteries produce electricity through the interaction of chemicals contained in the battery body. Primary cells include chemicals such as zinc, carbon or silver that produce electricity when combined in the right proportions. This process causes chemicals to deteriorate; When they have deteriorated, the point that they no longer create electricity, the battery is unnecessary and must be discarded or recyKlisted. The battery could not be re -used without changing chemicals, which would be a disproportionately expensive process.

storage batteries use different chemicals such as nickel, lithium and cadmium, to produce the same amount of electricity compared to primary cell batteries. These chemicals do not get worse so quickly, so storage batteries can be recharged and reused tens or hundred times. Unlike primary cells, they lose their charges over time, even if they are not used, so they are impractical for devices such as emergency flashlights or smoke detectors. They are also more expensive than primary cells, especially in combination with the cost of charging equipment.

Battery chemicals, whether primary or secondary, are generally toxic; Therefore, the batteries used should only be transported to a device that is approved to dip such chemicals. For this reason, storage batteries are more environmentally friendlyEnvironment than primary cell batteries. For devices such as cameras, electric tools, and laptops that are constantly used, the initial cost of storage batteries and chargers comparable cost of using disposable batteries throughout the service life of the device are higher.

Most car batteries are lead-acid batteries; They contain a fee for starting an electrical system of the car and can be recharged by connecting to a power supply or other automatic battery. Solar systems also use storage batteries that can be recharged by connection with solar panels. These solar systems can charge small devices such as laptops or mobile phones, or be converted to home current for everyday use.
