Professional presentation Principle and maintenance of lead acid battery,Let us learn more about the Principle and maintenance of lead acid battery.
Due to its safety and low price, lead-acid batteries are widely used and widely used. In different usage occasions, there are different usage requirements. In order to meet these requirements, various batteries with different structures are derived. When designing a circuit, choosing an appropriate battery structure will produce many benefits. This time, some commonly used …
The cycle life of lead-acid batteries is usually tested by the method of charge and discharge cycles. The test takes a long time, often several months. Mr. Ma Shaohua proposed the following technical test methods, which can greatly shorten the test time. The principle of accelerated life test The life of the product is directly …

Advantages and disadvantages of valve regulated batteries 1.1 Advantages of VRBsBecause the lean valve-regulated battery has no flowing electrolyte, the positive active material changes due to the change in the volume of charge and discharge, resulting in the weakening of the binding force between ions, and it will not produce convection and bubbles due to …

Ordinary lead-acid battery Lead-acid batteries produced in the 1950s are now called ordinary batteries, and users at that time had to have an “initial charging” process link when using the product. After the electrolyte is injected into the battery, the battery heats up. After the temperature of the electrolyte drops, the first charge is performed, …
Influence on battery internal resistance In lead-acid batteries, the resistivity of the electrolyte is thousands of times greater than the resistivity of various substances on the positive and negative plates. Therefore, under normal circumstances, the internal resistance of a fully charged battery is largely determined by the electrolyte. The internal resistance of a discharged battery …
Rational use of additives From the chemical reaction equation, it can be seen that PbO2, Pb and H2SO4 are the necessary substances to really participate in the reaction in the battery charge and discharge reaction. Now there are all kinds of additives in the market, which only play an auxiliary role. Through the role of …

Effect of temperature on battery performance It can be seen from the reaction equation that PbO2 is on the positive plate and Pb is on the negative plate. The conductivity of these two substances changes very little with temperature. Therefore, it can be said that the temperature effect of battery discharge performance is caused by …
The chemical reaction equation of a lead-acid battery says: PbO2+2H2SO4+Pb=PbSO4+2H2O+PbSO4 It can be seen from the reaction equation that PbSO4 is generated on the positive and negative plates after the discharge is completed. At this time, theoretically speaking, if the same substance is immersed in the electrolyte, there is naturally no potential difference, and there …
The chemical reaction equation of a lead-acid battery says: PbO2+2H2SO4+Pb=PbSO4+2H2O+PbSO4 It can be seen from the reaction equation that the acid in the electrolyte only participates in the electrochemical reaction. During charging, it changes from the combined state of the solid on the electrode plate to a new ecology and enters the electrolyte, and when …
From the reaction equation, it can be seen that a sufficient and necessary condition for battery discharge is to have an electron transfer circuit or other means to “transfer” the electrons on the negative electrode from the negative electrode to the positive electrode. This “moving” can be continuous or intermittent; it can be external or …
