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.

In order to prolong the service life of the battery and avoid failures such as breakdown, we should pay attention to the following points in the maintenance of the battery:

Several misunderstandings in the process of using batteries in general:
1. When using maintenance-free batteries, simply think that maintenance-free means that no maintenance is required.

Maintenance free battery means that it is not required to be overhauled and maintained from the time of delivery to the time when it is in the hands of users until the end of its service life. The maintenance free battery is a sealed single battery and cannot be disassembled. What are the reasons for maintenance free lead-acid batteries?

There are many factors affecting the capacity of lead-acid batteries: discharge rate, temperature, termination voltage, plate geometry, electrolyte concentration, etc.

The rubber cap is a very important part of the small VRLA battery, also known as the exhaust valve. The opening and closing pressure of the rubber cap is a very critical performance indicator.
