Opening the lead-acid battery means opening the safety valve on the lead-acid battery to directly see the interior of the battery. The safety valve of the lead acid battery is located below the safety valve cover of the lead acid battery. The safety valve cover is generally glued or ultrasonic welded to the large cover of the lead acid battery. Make up water for lead-acid battery according to the following operating procedures.

Many people don't know whether they can add water to lead-acid batteries. In fact, they can add water by themselves. The danger is that they are afraid of the sulfuric acid splashing out. Therefore, they need to wear rubber or plastic gloves when adding water. In addition, it is meaningful to add water when the charge is not switched on. Adding water indiscriminately is not only beneficial, but harmful. In addition, distilled water should be added instead of other things. The amount should not be too much.

Lead-acid batteries are mainly composed of negative elemental lead, positive lead dioxide, electrolyte and separators. The PE separator is between the positive and negative plates of the battery, which can prevent the positive and negative plates from directly contacting and discharging to cause short circuit. At the same time, there are a certain amount of holes on the separator to ensure the passage of positive and negative ions and prevent open circuit. Therefore, the importance of the separator is no less than that of the positive and negative plates of the battery. At present, it is generally believed that the explosion accident caused by the short circuit of the lead-acid battery is mainly caused by the aging of the separator.

The damage to the battery varies with the degree of heating of the battery. As long as the battery works, it will heat up. That is because the chemical substances inside the battery are active and react to release energy during the discharge process. However, if the battery discharges too fast, it may be that the battery capacity is small and the discharge current exceeds 0.5C for a long time. It is emphasized here that although the battery consumes a certain amount of power after a short drive, after it is stationary, the battery has a recovery process, and the electrochemical process of the electrode plate continues, so the voltage will rise, but it does not mean that the capacity will rise; On the contrary, when driving for a long distance without stopping on the road, the electrification of the electrode plate and the consumption of electric energy are carried out at the same time.

Mainly divided into three states (the color of the battery eyes of different manufacturers may be different): look at the color of the battery "eye", for example: green or blue means it is in good condition; black or red means it needs to be charged; white means the battery needs to be replaced.

The internal resistance of lead-acid battery refers to the resistance that the current flows through its interior when the battery is working. It is generally divided into AC internal resistance and DC internal resistance. Because the internal resistance of the rechargeable battery is very small, the polarization internal resistance is generated due to the polarization of electrode capacity when measuring the DC internal resistance, so its true value cannot be measured. However, the AC internal resistance can be measured without the influence of the polarization internal resistance, and the true internal value can be obtained.

1. The internal resistance of the battery consists of ohmic polarization (conductor resistance), electrochemical polarization and concentration polarization resistance. During the charging and discharging process, the resistance changes, and the internal resistance changes from large to small, on the contrary, the internal resistance increases.

The most common problem is the difficulty in starting. Of course, this does not mean the difficulty in starting in the cold environment (the difficulty in cold starting in the cold region is mostly caused by the oil mark). For example, starting the car in normal time only takes more than 1 second, but becomes a 3 second starting time; Secondly, the fuel consumption is increased due to the uncertainty. The reason is that after the battery decays, it is not durable or easy to fill. The engine is always busy charging the battery, so the fuel consumption will naturally increase; Secondly, when idling, the lights will suddenly dim, which is also caused by insufficient speed.

During the production and design of commonly used storage batteries, the thicker end of the battery pile is a positive electrode, and the thinner end is a negative electrode. At the same time, you can identify the color of the battery pile. The positive electrode pile is dark brown, while the negative electrode is dark gray. In addition, the positive and negative marks of some batteries are expressed in English letters, that is, P represents positive electrode, and N represents negative electrode.

The colloidal battery uses a type of gel-like electrolyte. There is no free liquid inside, but there is a certain amount of "free water". The main components of the colloidal electrolyte are gelling agent and sulfuric acid, so can water be added to the colloidal battery? In fact, due to the airtightness of the colloidal battery, the water emitted is very rare and can be ignored. What if you add water blindly?

The super battery is a kind of hybrid energy storage element, which is composed of two parts, including the lead-acid battery part and the asymmetric super capacitor part, which are connected in parallel in an internal non control circuit mode. The super battery realizes the integration of lead acid battery and super capacitor in terms of structure design and battery use function. The so-called integration is to combine the above two in the same single battery system.
