Lead-Acid battery – this is the most common type of batteries. It was invented a very long – even in 1859. This mechanism is mainly used in road transport and in the emergency sources of electrical energy.

lead Acid battery

The Principle on which operates lead-acid battery based on electrochemical reactions of lead dioxide and lead in the environment of sulfuric acid. Energy arises as a result of the interaction of sulfuric acid and lead oxide. Studies that were carried out a long time ago, gave the following result: inside the battery there are about 60 reactions (as a minimum) and one third of them occur without electrolyte acid. During the discharge starts lead oxidation occurring on the cathode and recovery of lead dioxide (at the anode). Reverse reactions occur during charging. So, if lead-acid battery is discharged, the flow is sulfuric acid (this decreases the density of the electrolyte).

Now should tell you how designed this unit. It is created by connecting the positive and negative electrodes and separators (so-called separating insulators). They are immersed in the electrolyte. Electrodes – lead grating. Negative have an active substance called "spongy lead", and positive – lead dioxide.

Lead-Acid battery can be classified according to various characteristics and parameters. You should list them. This:

  • Maximum operating time;
  • Battery capacity
  • Number of charge cycles;
  • The parameters of self-charging;
  • Dimensions;
  • Operating temperature;
  • The ability to conduct accelerated charge;
  • Maximum shelf life.

Lead-Acid battery can be made in the form of several items or one. The electrolyte that is located inside the battery may be in a gel state or a liquid. In the second embodiment, the battery will require no maintenance, refilling water and replacing the electrolyte. A helium service is not needed, therefore, are considered more convenient.

Car batteries vartaIt is Impossible to discuss a topic such as Varta car batteries. This firm is the first supplier of batteries for cars across Europe. Today Varta car batteries – a great choice for anyone who wants to buy a reliable machine which will last a long time without any maintenance. Manufacturers impose very stringent, the increased requirements for their products. A little more companies, in addition to this, what can give high quality results and provide the automotive market with good batteries. They differ from the others by high power and highest starting current. All this ensures that the motor will run even under the most critical and seemingly unrealistic conditions. In addition, this is ideal for diesel engines.
