Many people don't understand that the lead-acid battery can add water. In fact, I can completely add, dangerous is fear of sulfuric acid inside, wear rubber or plastic gloves, and when charging does not transferee, add water to mean, add water Not only there is no need, but harmful, and to add distilings, don't add other things, don't be much more, the amount of water-acid battery is taught, and the problem to pay attention to. Science: What is a lead-acid battery? The electrode is important from lead and its oxide.

The electrolyte is a battery of the sulfuric acid solution. In the state of discharge, the important component of the positive electrode is a lead, negative electrode is lead; in the state of charge, the important components of the positive and negative For the lead of sulfate, it is divided into an exhaust battery and a maintenance lead-acid battery. The battery is important from a tube positive electrode plate, an a negative plate, an electrolyte, a partition, a battery tank, a battery cover, a pole column, a liquid cover, and the like.

Generally used are lead-acid storage batteries, which is generally the same as UPS to supply power supply to the computer room equipment. What kind of battery should be hydrated? 1, the lead-acid battery of the lead-acid battery decreased below 20% is severe, must. 2, the capacity dropped to 40% or less, more than 20% of the lead-acid battery, more water, recommended to repair the water.

3, the capacity dropped to 60% or less, more than 40% of the lead-acid battery is not much shortage, if there is conditional hydrating battery repair effect will be better. 4, the capacity of less than 60% is basically no shortage of water, no need to add. 6 single hydration of lead-acid batteries should be normal when it is normal.

Specifically, each lead-acid battery is hydrated, and the degree of loss of lead-acid battery is to be seen. In summary, the presence of the lead-acid cells in each single-generation of the lead-acid battery should be ensured during the entire repair process: How much is the general lead-acid battery plus water? A 12V lead-acid battery has 6 monosaki, and the total amount of each monobotic electrolyte is about tens of tens to more than 20 ml according to the battery capacity. The portion that is usually supplemented only to several tens of milliliters, the method and the step of adding water in the lead-acid battery in the electrolyte: Open the lead-acid battery refers to the safety valve on the lead-acid battery , Can directly see the interior of the lead-acid battery.

The position of the safety valve of the lead-acid battery is below the safety valve cover of the lead-acid battery, and the safety valve cover is generally adhesived or welded to the lead-acid battery cover with adhesive or ultrasonic welding. Water supply for lead-acid battery should be carried out in accordance with the following operations. 1, ready to work.

The electrolyte electrolyte with distilled water and pure sulfuric acid, the ratio is: 500 mL, distilled water, add 0.5 ml, pure sulfuric acid. Preparing standard rubber safety valve spare.

Tools are: replay cone, suction (can be replaced with disposable needles), transparent polyethylene tube, diameter suitable for pipetting (needle tube) suction, ABS glue. 2, open the cover of the lead-acid battery along the exhaust hole. Some lead-acid batteries of the lead-acid batteries are ABS adhesive, some lead-acid batteries are connected with buckles.

Note that when you open the cover, don't damage the cover. At this time, you can see the rubber cap of 6 safety valves. 3, open the rubber cap, expose the exhaust hole, can see the inside of the lead-acid battery through the exhaust hole.

Some lead-acid battery safety valves can be centered, and some fillers are surrounded around the rubber cap of some lead-acid batteries, pay attention to the filler. 4, inhale the formulated electrolyte with dropper, injection of the electrolyte from the exhaust hole. Electrolytic solution should just cover the polar plate 1mm.

5, cover the lead-acid battery exhaust hole of the electrolyte of the electrolyte, covers the gas permeability to prevent the dust falls. After standing 24h, observe if there is a flowing electrolyte (free acid) inside the exhaust hole, if there is no supplementary electrolyte. 6 single hydration of lead-acid batteries should be normal when it is normal.

Specifically, each lead-acid battery is hydrated, and the degree of loss of lead-acid battery is to be seen. In summary, in the entire repair process, it should ensure that there is a single single-generation of the lead-acid battery. In the exhaust hole, the 2OCM long transparent polyethylene cannula is connected to the lead-acid battery of the nominal I2V, 16.

2V constant voltage limit charging in the lead-acid battery nominal I2V without coverage. Preferably, the lead-acid battery is placed in an acid-resistant container to prevent overflowing electrolyte contamination and corrosion equipment. After the charging to the red light starts flashing for 3 hours, it is considered that the lead-acid battery is charged for the first time.

When the lead-acid battery is added to or supplemented water, attention should be paid to what is the electrolyte of the lead-acid battery is an aqueous solution of sulfuric acid. The electrolyte in the lead-acid battery is the component of the reaction, so the capacity of the battery has an electrolyte in the battery. Direct dependencies.

Usually the loss of power of the power VRLA lead-acid battery refers to the electrolyte loss of moisture. It is important that the water loss is important: (1) hydrogen or oxygen generated by hydrogen electrolysis is separated from the battery; (2) The grid is corroded to convert lead (PB) into a neutral (PBO2) process, oxygen Absorbs lose the oxygen in the aqueous component; (3) water vapor can also be lost directly through the shell wall of the battery; (4) water vapor in the battery with hydrogen and oxygen yet. When the battery is hydrated, it should be paid to the following problems.

After the battery hydration is completed, it is checked whether the lead-acid battery pole surface is also electrolyte: if there is no electrolyte, the electrolyte will be charged again; if there is an electrolysis in 6 Liquid, absorb excess electrolyte with straw. Any lead-acid battery that is to be hydrated is before, the lead-acid battery operates in a highly sulfuric acid battery, and the lead-acid battery or the light or heavy existence of this vulcanization, so the lead-acid battery after hydrating is required. Pulse.

Pay attention to the following points when adding an electrolyte or supplementing water to a lead-acid battery: (1) Electrolytic solution high over the polar plate L.0--1.5mm.

For the lead-acid battery with two red lines, the electrolyte must not exceed the red line. The electrolyte is too full to overflow the small hole from the lead-acid battery. Because the electrolyte is electrically conductive, once the lead-acid battery is positive, the negative two is formed, the self-discharge circuit is formed.

In this case, the electrolyte should be wipe off, or rinse with water. (2) If there is anything inadvertent when adding electric to the electrolyte, don't go fishing with a metal, apply a wooden stick to clamp the impurities. If the wire or copper wire is removed, the metal molecules will be self-discharged from the corrosion of sulfuric acid, and the lead-acid battery is damaged.

(3) In the process of charge and discharge repair, the lead-acid battery will gradually decrease due to electrolysis and evaporation, resulting in a decrease in electrolyte liquid. If it is not supplemented in time, it is possible to shorten the life of the lead-acid battery, and should be supplemented with distilled water in time.
