The start-stop battery safety valve is a type of safety device used to control the internal pressure of start-stop batteries. Its particular feature is its ability to prevent overpressure and gas buildup within the battery during operation.

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.

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.

Under the same specification, the volume of lithium iron phosphate battery is only half of that of lead-acid battery, and the weight is only 35% of that of lead-acid battery. Theoretically, the space is completely enough. However, it is necessary to consider whether it can still be installed in the original position, and whether it protrudes or is squeezed.

One of the obvious differences between dry cell batteries and wet cell batteries is that the electrolytes of wet cell batteries are liquid, while the electrolytes of dry cell batteries are colloidal or solid. They have different advantages and disadvantages due to different manufacturing materials. So which is better between dry cell batteries and wet cell batteries? ​

The battery safety valve, also known as the battery exhaust valve, is a valve that acts as a safety protection valve on a valve-controlled battery. When the battery is working, the internal pressure of the battery is gradually increased due to the internal reflection of the released gas. When the pressure reaches the valve opening threshold, the safety valve automatically opens to discharge the gas. After the internal pressure of the battery drops to the valve closing threshold, the safety valve automatically closes. At the same time, during this process It can prevent external gas from entering the battery and acid splashing in the battery. It can avoid the bulging and explosion caused by excessive pressure in the battery or the oxidation failure of the battery reaction solution caused by the entry of external gas into the battery.

The length of the service life of the car battery depends on the structure and quality of the battery on the one hand, and is closely related to the daily maintenance on the other hand.The following aspects are what we need to pay attention to.
