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.

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.

The batteries of traditional automobiles and new energy vehicles are divided into lead-acid batteries, nickel metal batteries, lithium ion and lithium polymer batteries, high temperature sodium batteries, metal air batteries, super capacitors, flywheel batteries, solar cells and graphene batteries, etc. There are two kinds of starting power supply and power supply. So far, electric vehicles are still inseparable from lead-acid batteries.

There has always been such a voice in the battery industry: that the quality of life of lead-acid batteries in recent years is not as good as before, especially in winter, it is even less durable. Although many manufacturers say that their batteries can be used for two or three years without any problems, in practice, there are still many users who feel that the batteries need to be replaced in about a year and a half. Is the life of lead-acid batteries really becoming more and more useless? How long is the service life of a normal battery? To answer this question, we must first understand a premise, how to define the service life of lead-acid batteries.
