The rechargeable batteries, best described as charge accumulators electric, I'm batteries whose charge can be completely restored by supplying electricity. The rechargeable batteries the most common are the classics stylus batteries of type AA and le batteries present in portable electrical devices such as smartphones, notebooks, tablets, ereaders ...

The sector of rechargeable batteries it is booming and manufacturers are moving in different directions. The need for development ofelectric batteriesincreasingly powerful is dictated by market needs on two fronts. On the one hand, the automotive sector, for electric mobility, and on the other, the energy sector for the need to store electricity produced from clean sources.

The duration of rechargeable batteries
The duration of rechargeable batteries it can vary greatly depending on the technologies used for the production of electric charge accumulators. Between rechargeable batteries commonly used (AA batteries, AAA mini batteries…), the most popular are the branded ones Duracell and Beghelli, among the many available on the market we point out the models eneloop from Panasonic which offer up to 3,000 charge cycles.

The battery life of notebooks, smartphones and other portable devices that take advantage of lithium battery technology can be increased by following low energy consumption strategies (do not leave applications open in the background, decrease display brightness, deactivate vibration, deactivate the bluetooth and wifi functionality when not in use ....), as well as the life cycle of the rechargeable batteries it can be increased by following other good practices.

We often ask ourselves: "Is it better to completely discharge the battery before recharging it, or to recharge the battery when there is still some remaining charge? "
This question is not only legitimate but also intelligent!
Some types of rechargeable batteries are susceptible to damage due to complete discharge (for example, the rechargeable batteries lead or lithium ion) so, for extend the lifespan of the rechargeable battery you should never let the device completely download.

When to recharge notebooks and smartphones?
For notebooks, smartphones, tablets or other devices with rechargeable batteries lithium-ion, it is good to provide a full recharge before the energy availability of the accumulator drops below 20 percent of energy.

Other types of rechargeable batteries, unlike lithium-ion ones, they are sensitive to the so-called "memory effect ", also known as lazy battery. In this case the batteries it needs to be recharged only when it is fully discharged to avoid rapid performance degradation.

Types of rechargeable batteries
Based on the use, the market provides a wide range of accumulators of electric charge. The research is moving towards the development of rechargeable batteries more efficient and with shorter charging times. Here is a short list of technologies already widespread and those in the process of being tested:

  • Lead-acid batteries
  • Gel batteries
  • Solid electrolyte batteries
  • Li-ion batteries
  • Lithium-ion polymer batteries
  • Sodium sulfur batteries
  • Nickel-iron batteries
  • Nickel metal hydride batteries
  • Nickel cadmium batteries
  • Sodium metal chloride batteries
  • Zinc nickel batteries
  • Sodium Air Batteries - Lithium Air Batteries
  • Molten salt batteries
  • Zinc silver batteries
  • Bicarbonate batteries

Disposal of rechargeable batteries
Disposing of accumulators is by no means a simple task. When it comes to batteries, the task of every citizen is to place them in the special transparent columns located outside commercial parks and various sales outlets. When it comes to car batteries, luckily many car manufacturers have implemented recovery and recovery systems; no less important is the "raw material", thanks to battery disposal it is possible to recover the so-called "rare earths", precious elements for the electronics industry.

    Granted, this is a great option

    I apologize, but in my opinion you admit the mistake. I can prove it. Write to me in PM, we will discuss.

    Does anyone know about radio here? We need a colleague who would tell briefly about the T2 transistor (it is not clear how to check rv = rv1). Hopefully there are radio amateurs here. If completely off topic, then I'm sorry. I have to write, I just don't see a way out. PS: if the spelling is not correct then also excuse me, I'm only 13 years old.
