Electronic scale with 12V4AH, VRLA battery capacity and voltage attentionTwo maintenance methods

Battery for cars will be used for more than 2 years, and capacity and discharge capabilities will decline. The general car battery life will not exceed 4 years. Of course, the life of a good battery will be longer. Let’s take a look at the maintenance method of water-type lead-acid batteries and maintenance-free lead-acid batteries.

Maintenance-free lead-acid battery

Quote: Regularly check the magic eye and keep the power sufficient.

Due to the maintenance-free battery, there is no water hole and the battery fluid level scale. We need to judge the status of the battery through the “Magic Eye” on the battery. The eye is green to indicate the battery is normal, charging foot; the magic eye is black indicating that it is necessary to charge; the eye is white to indicate that the battery needs to be replaced.

In addition, we generally use a voltmeter to check the battery voltage, although the voltage value of the battery can be detected but cannot check the capacity of the battery with load capacity. To check the actual situation of the battery, we should use a dedicated battery detector to check the battery’s discharge capacity and the capacity of load.

Water-based lead-acid battery

Pay attention to: battery fluid level and battery fluid density

The battery fluid of the lead-acid battery is made of sulfuric acid and distilled water. When the battery is discharged, the water will increase and the sulfuric acid will increase, which results in a decrease in the density of the battery fluid; when charging, the water will increase, and the sulfuric acid will change. The concentration of the battery reflects the ratio of water and sulfuric acid in the battery fluid. Normal electrolyte density is 1.28 (summer) / 1.29-1.30 (winter) (in the unit is gram per cubic centimeter).

As a owner, we should regularly check the liquid level. When the battery fluid is insufficient, distilled water should be added to a suitable level. After adding distilled water to the battery, we should check the battery fluid density, and keep the battery fluid density within a reasonable range.

Huizhong battery big precautions

1. The electrode terminal of the battery is where the season is prone to problems, so pay attention to check at any time. Check that the circuits have no aging or short circuits. Prevent batteries from retreat in advance because of over-discharge. If there is a green oxide at the electrode wiring, it is necessary to remember that the boiling water is rushed away. If these green oxides are not cleared, it will cause the generator’s power generation, so that the battery is in a loss, it will cause a battery when it is serious. Early scrap, or can’t do it. After rushing by boiling water, use compressed air to dry water, then spray the dedicated protective agent to prevent the oxide layer from appearing again.

2. The ignition system maintenance is about whether the vehicle can start, so it should be carefully examined to see if it is rust. Once rust, you should use a professional cleaning agent. In addition, the maintenance of the spark plug cannot be dropped light.

3, the charging system is to focus on whether the generator belt has aging in the raining, and there is aging or cracking. If the above is not happened, you should also remember to see the tightness of the belt. The belt is too loose, which will cause the belt to make the belt early; the belt is too tight, which will cause the generator bearings to be partition.

4, the battery is long long, it will slowly discharge it, until scrapped. Therefore, a car should be started every other period of time to charge the battery. The battery has a certain service life to replace it in a certain period of time.

5. Sometimes the engine flameout starts on the road. As a temporary measure, it can help other vehicles, and the vehicle on their vehicles can be used to initiate the vehicle, and the negative electrode and negative electrode of the two batteries are connected, the positive electrode and the positive electrode are connected.

6, the density of the electrolyte should be adjusted according to the standard according to the standards in different regions.
Wuxi Huizhong Weiye Electric Co., Ltd. has a large sealed lead-acid battery capacity: 2V200AH, 2V250AH, 2V300AH, 2V350AH, 2V600AH, 2V800AH, 2V1000AH, 2V1800AH, 2V2000AH, 2V2500AH, 2V2000AH, 2V2500AH, 2V3000AH, 2V4000AH.
7. Distilled water or special replenishment should be supplemented during lack of electrolytic solution. Don’t use drink pure water instead. Because pure water contains a variety of trace elements, the battery will cause adverse effects.

8. When starting the car, the start of the starter is not intermittently caused by over-discharging. The correct way to use is that each time the launch has a total length of no more than 5 seconds, and the startup time is not less than 15 seconds. The cause should be found from the circuit, ignition coil or oil passage in other ways such as circuit, ignition coil or oil.

9. Whether the small holes on the battery cover should be checked frequently when driving daily. If the battery cover is blocked, the generated hydrogen and oxygen can not be out, and when the electrolyte is expanded, the battery housing is broken, affecting the battery life.

Pay attention to the following points when purchasing a mobile phone lithium-ion battery:

First, the cadmium battery of the spot is 500mAh or 600mAh, and the nickel-hydrogen battery is not 800-900 mAh; and the capacity of lithium ions is generally between 1300-1400mAh, so the time for the lithium-ion battery is only nickel. 1.5 times the hydrogen battery is about 3.0 times the nickel-cadmium battery.

Second, look at the appearance of the authentic battery anti-wear surface is uniform, use the PC material, no criticism; the counterfeit battery is no anti-wear or too rough, using the regeneration material, easy to brush. The genuine mobile phone battery surface is clear, uniform, clean, no obvious scratches and injuries. The five gold plates have no obvious scratches and black, green phenomenon, the color of the battery is consistent with the mobile phone body, well with the mobile phone, and the lock is reliable.

Third, see the mark original battery label should be printed with the battery model, type, rated capacity, standard voltage, positive and negative sign, and manufacturer name.

IV. Seeing the inside of the protective device should have an overcurrent protector inside the battery. When the current short circuit, the current is too large, and the circuit is automatically cut off to avoid burning or damage the phone. If during the charging process, it is found that the battery is severely generated, smoke, or even exploded, indicating that the battery is definitely fake.

5. See the anti-counterfeiting sign such as the NOKIA original battery’s sticker NOKIA word, the anti-counterfeiting trademark of the Motorola battery is rhombus, and no matter from any point of view, there is a stereo effect. On the contrary, the anti-counterfeiting sign is dark, and the three-dimensional sense is probably a fake.

6. If the voltage is used to fake the lithium ion mobile phone battery block with nickel-cadmium, the nickel-hydrogen battery block must be composed of five monomer batteries. The charging voltage of a single battery is generally not more than 1.55V, and when the battery block is lowered below 8.0V may be nickel-cadmium and nickel-hydrogen batteries.
