The lead-acid battery (VRLA) is an electrode important from lead and its oxide, and the electrolyte is a battery of sulfuric acid solution. In the lead-acid battery 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 electrode are the lead of sulfate. How to test the lead-acid battery? A nominal voltage of a single lead-acid battery is 2.

0V, which can be discharged to 1.5V, which can be charged to 2.4V; in use, it is often used in series with 6 single lead-acid batteries to consist of a lead-acid battery that is 12V.

24V, 36V, 48V osv. Electrochemical reaction valve controlled lead-acid battery in electrode is as follows. Opladning er at tilslutte ekstern jævnstrøm til batteriet, så den elektriske energi omdannes til kemienergi.

Afladning er, at den elektriske energi frigives fra batteriet til at drive eksternt udstyr. When the VRLA battery charging will reach the vertex, the charging current is only used to analyze the water in the electrolyte. At this time, the battery is censusing oxygen, the negative pole is born with hydrogen, and the gas will overflow from the battery, resulting in reduction of the electrolyte, need not to add water on time.

On the other hand, under the end of the charging or overcharge conditions, the charging energy is used to analyze the water, the positive pole-generated oxygen and the negative sponge lead, so that a portion of the negative electrode is in a unpleassed state, inhibiting the negative of the negative hydrogen. How to test the lead-acid battery of the lead-acid battery is a lead-acid battery that is often used in everyday life. Sometimes it will not be able to do it, go to the maintenance point 4S shop, they usually offer you new No need.

How to test the lead-acid battery? 1. First, you have to check the battery's electro-eye to judge the good or bad, in general, the green is good, red is bad, white or black is to charge or add the electrolyte, this detailed look at the density ball to see the electro-eye What color, explain, generally stated. 2.

For det andet opladning af batteriet. Generally, one-time charging is around 8 hours, and it can restore about 80% of the capacity of the new battery, and it can be continuously used. 3.

Efter opladning vil den ikke slå ilden. If the tester is tested, it will continue to discharge in 5- seconds in a normal discharge. If the discharge voltage is less than 8 volts, it will illustrate the battery problem, because you are a battery that is just charge, no There is a loss of loss.

4. Next, use the discharge instrument to continue monitoring, turn the battery's single-skin, press the discharge button, if there is any single-handed sustained bubble, then that single-hand is damaged, record it. 5.

Then use the densitometer to detect each monurractable density, if the density of the single line is larger than other single-density, then the single-handed is damaged. Replacing a single-handed professional operation, if you are not a professional, offer you to replace the battery, or ask a professional repair. Use conditions (1) to prevent direct contact with the metal container pen, should use an acid and heat-resistant material, otherwise it will cause smoke or combustion.

(2) Charge the specified charger under the specified criteria, otherwise it may cause overheating of the battery, deflation, leak, burning or crushing. (3) Installer ikke batteriet i en forseglet enhed, da det ellers kan lave udstyret. (4) Når du bruger batteriet i en medicinsk enhed, skal du installere backup-strømmen uden for hovedstrømforsyningen, ellers vil hovedstrømsvigtet forårsage skade.

(5) Place the battery away from the place where the spark equipment is kept, otherwise the spark may cause the battery to smoke or break. (6) Do not place the battery near the heat source (such as transformers), otherwise it will cause battery overheating, leakage, burning or crushing. (7) When using the number of medium batteries more than one, make sure that the battery connection is correct and the charger or load connection is incorrect, otherwise the battery is broken, burned or battery damage, and in some cases will hurt people.

(8) Pay special attention to let the battery are on the foot. (9) Batteriets specificerede brugsområde er som følger. At være uden for dette område kan forårsage batteriskade.

The normal operating range of the battery is: 77.f (25 ¡ã C) Battery after discharge (mounted in the equipment): 5.f to 122.

f (-15 ¡ã C to 50 ¡ã C) After charging: 32.f to 104.f ( 0 ¡ã C to 40 ¡ã C) medium: 5.

f to 104.f (-15 ¡ã C to 40 ¡ã C) (10) Do not put the battery mounted on the locomotive at a high temperature, direct sunlight, the stove or fire, otherwise May cause battery leakage, fire or broken. (11) Do not use the battery in a dusty place, it may cause battery short circuit.

Når du bruger batterier i et støvfrit miljø, skal du kontrollere batteriet regelmæssigt. Levetid 1, udledningsdybde udledningsdybden stoppes i færd med at udledes under processen. 100 % dybde, der peger på al kapacitet.

Lead-acid battery life is affected by discharge depth, the focus of design consideration is deep cycling, shallow cycling or floating charge. Hvis batteriet, der bruges af den lavvandede cyklus, bruges i dyb cyklus, vil bly-syre-batteriet hurtigt svigte. Da den neutrale binding af den positive elektrode aktivt materiale ikke længere er bundet, genereres ledningen, når afladningen aflades, og ladningen genoprettes til ledningen, det molære volumen af ​​ledningen af ​​ledningen af ​​cellerne er større, og den aktive materialevolumenudvidelse udvides, når den aflades.

If a molar oxide is converted to lead, the volume is added 95%. Således gentagne kontraktioner og ekspansion, er den indbyrdes binding mellem partiklerne af de neutrale partikler gradvist afslappet, og det er let at falde af. If the active material of a molar of the elixir is only 20% discharge, shrink, the extent of expansion is greatly reduced, and the combination resistance is slow.

Derfor, jo dybere udledningsdybden er, jo kortere er dens cykluslevetid. 2 Shorten the use period when overcharge. 3, the temperature of the temperature of the lead-acid battery life is extended with temperature rise.

At 10 ¡ã C 35 ¡ã C, each liter is 1 ¡ã C, about 56 cycles, between 35 ¡ã C 45 ¡ã C, 25 ¡ã C, 25 cycles per liter, more than 50 ¡ã C, due to negative electrode vulcanization capacity Loss and reduced life. Batterilevetiden øges med temperaturen i et bestemt temperaturområde, fordi kapaciteten øges med temperaturstigninger. If the discharge capacity is unchanged, the discharge depth is lowered, and the lack of life is prolonged at the temperature rise.

4, the concentration of sulfuric acid affects the addition of acid density, although the positive electrode plate capacity is advantageous, but the self-discharge of the battery increases, the corrosion of the grid also accelerates, which also causes the looseness of the lead in the cell, and the acid density is used in the battery. Added, low cycle life. 5, the effect of discharge current density increases with the discharge current density, the battery life is lowered, as the positive electrode neutral is loose falling off under large current density and high acid concentration conditions.

How to test the lead-acid battery? Installation and commissioning (1) Use tools with insulated sleeves such as pliers, etc. Brug af ikke-isoleret værktøj kan forårsage batterikortslutning, feber eller forbrænding, beskadige batteriet. (2) Anbring ikke batteriet i et lukket rum eller i nærheden af ​​brandkilden, da det ellers kan forårsage eksplosion eller brand på grund af den brint, der frigives af batteriet.

(3) Brug ikke fortynder, benzin, petroleum eller syntetisk væske til at rense batteriet. Using the above material can cause the battery case to crush the leak or fire. (4) When a 45 volt or higher voltage is resolved, take safety steps to bring insulated rubber gloves, otherwise it may be shocked.

(5) Anbring ikke batteriet et sted, der kan blive oversvømmet. If the battery is immersed in the water, it may burn or .
