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.

AGM sealed lead-acid battery uses pure sulfuric acid aqueous solution as electrolyte, and its density is 1.29-1.3lg/cm3. Except for a part of the electrolyte absorbed inside the plate, most of it exists in the glass fiber membrane. In order to provide a channel for the oxygen precipitated from the positive electrode to the negative electrode, it is necessary to keep 10% of the pores of the separator that is not occupied by the electrolyte, that is, a lean liquid design. In order to make the electrode plate fully contact the electrolyte, the electrode group adopts the method of tight assembly.

PE battery separator has many effects on the performance of lead battery. Every improvement of separator quality is accompanied by the improvement of lead battery performance. The main function of PE battery separator is to prevent short circuit between positive and negative electrodes, but it cannot significantly increase the internal resistance of the battery. PE battery separator is mainly used to prevent short circuit between positive and negative electrodes, but it cannot significantly increase the internal resistance of the battery. Therefore, the separator should be porous, allowing free diffusion of electrolyte and ion migration, and has a relatively small resistance. PE battery separator shall not reach the opposite electrode plate through fine holes, that is, the hole diameter shall be small, the number of holes shall be large, and the total area of the gap shall be large.

PE separator is a new type of separator after rubber separator, glass fiber separator and polyethylene (PVC) separator. It has the advantages of high porosity, small pore size, low resistance, good toughness and sealability. Prevent edge short circuit, reduce active material shedding, and improve battery life.

Whether it is a valve-regulated sealed lead-acid battery using glass fiber diaphragm (hereinafter referred to as AGM sealed lead-acid battery) or a valve-regulated sealed lead-acid battery using colloidal electrolyte (hereinafter referred to as colloidal-sealed lead-acid battery), they all use the principle of cathode absorption to make The battery is sealed.

There are two types of valve-regulated sealed lead-acid batteries (VRLA) today, namely, glass fiber separators (AGM) and silicon gel (Gel) are used to "fix" the sulfuric acid electrolyte in two different ways. They both use the principle of cathode absorption to seal the battery, but the channels provided for the oxygen evolved from the anode to reach the cathode are different, so the performance of the two batteries is different.

AGM battery refers to the battery whose separator is made of ultra-fine glass wool material. At present, the German department and the American department mainly promote AGM technology. Compared with ordinary batteries, the price is more than three times more expensive, but it has the following advantages:
