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.

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.

1. Due to the advantages of its own structure, the loss of lithium battery electrolyte is very small, and there is basically no need to replenish distilled water in time during the service cycle. It also has the characteristics of shock resistance, high temperature resistance, small size and low self-discharge rate. The use cycle is generally twice that of ordinary batteries.

According to the types of batteries currently owned by the market, batteries can be roughly divided into two types: traditional lead-acid batteries and maintenance-free batteries that have been popularized in recent years.

During the application process of lead-acid batteries, it is necessary to carry out irregular safety performance evaluation inspections to ensure their normal operation and avoid losses caused by their failures.

As a traditional battery, lead-acid battery has become a common battery in daily life due to its low cost and rechargeable advantages. Adding water for repeated use is a common method, so when the liquid level of the lead-acid battery is too low, under what circumstances is it allowed to add water to make it work better?

A 0.25mm thick glass fiber layer made of coarse glass fiber is pasted on both sides of the battery separator. The battery separator improves performance, prevents the battery separator from shrinking and loosening, and improves the ability to retain electrolyte. Since the battery separator has a protective effect on the performance of the lead battery, the main function is to prevent the short circuit of the positive and negative electrodes, but it cannot significantly increase the internal resistance of the battery. The battery separator should be porous, allow free diffusion of electrolyte and ion migration, and have relatively low electrical resistance. When some of the active material falls off, it must not pass through the pores to reach the opposite plate.

Protect the charger: There are instructions on protecting the charger in the general instruction manual. In order to reduce costs, the current chargers are basically not designed to be highly resistant to vibration. In this way, the chargers should be wrapped with soft materials such as raincoats to prevent vibration and bumps. After many chargers vibrate, their internal potentiometers will drift, causing the entire parameters to drift, resulting in abnormal charging status. Another thing to pay attention to is to keep the charger ventilated when charging, otherwise it will not only affect the life of the charger, but also may cause thermal drift and affect the charging state. This will damage the battery. Therefore, it is also very important to protect the charger;

1. Compared with many traditional separators, PE separator has the strongest oxidation resistance from the material point of view. However, due to its soft texture and thin base thickness, PE separator is deformed during battery charging and discharging, which is easy to cause heat loss and aggravate the thermal oxidation process of the separator.

The glass fiber separator used in the AGM sealed lead battery has a porosity of 90%, and sulfuric acid is adsorbed in it, and the battery adopts a tight assembly form, so the diffusion and electromigration of ions in the separator are very little hindered, so the AGM sealed lead battery has Low internal resistance, high current and fast discharge capability.
