Every year when entering the winter, it is the peak period of battery replacement, because the important indicator that shows the performance of a battery is the low temperature and high current discharge capacity. Deteriorated batteries may still function normally during high summer temperatures, but in the winter, engine oils have a high viscosity and require more current to start. However, at this time, the battery has been unable to output the current at the normal temperature due to the influence of low temperature, not to mention the large current required in winter, so it is inevitable that the engine cannot be started. The average life of the commonly used start-up battery is also about three years, and beyond this time, the performance will be degraded. If the vehicle starts with difficulty at a low temperature, it is recommended to replace it in advance. However, there are many kinds of battery products on the market today. Many people may not know which one is better. Today, I will briefly introduce to you the types of batteries currently available and their respective advantages and disadvantages. ◠Ordinary lead-acid battery Ordinary lead-acid batteries The most commonly used start-up battery in trucks is this ordinary lead-acid battery, which has the advantages of low cost and large current at low temperature. However, since its internal working medium is a solution of water and sulfuric acid, water will be difficult to avoid evaporation and electrolysis during use, so it is necessary to regularly add distilled water to ensure the liquid level. Add battery replenisher It is precisely due to the nature of the maintenance required that the battery is often scrapped and damaged due to improper maintenance, because not everyone will properly maintain it. For example, distilled water should be added when the electrolyte level decreases, but some people will mistakenly add battery fluid to it, resulting in too high sulfuric acid concentration, or supplementing the battery with mineral water containing minerals or poor quality distilled water, which will cause the battery to be short. Damage is scrapped within the time. Lead-acid battery internal plate In addition, the plates of common lead-acid batteries are poor in vibration resistance, and the active materials on the plates will continuously fall off as they vibrate during use, causing the effective reaction area of ​​the plates to decrease continuously. Exfoliated active materials that accumulate at the bottom of the battery to a certain height can lead to short-circuits on the plates, causing severe self-discharge and causing the batteries to fail. Scrap battery Finally, ordinary lead-acid batteries cannot be stored for a long period of time after the addition of electrolytes and must be loaded on vehicles. Because the battery has the phenomenon of self-discharge, when the battery power is insufficient for a long time, the battery plate will undergo irreversible vulcanization and eventually cause scrap. ◠maintenance-free lead-acid battery The maintenance-free lead-acid battery is actually an upgraded version of an ordinary lead-acid battery. It has a fully-enclosed housing structure, and does not require maintenance during use. It eliminates the need for ordinary batteries to be supplemented with distilled water. It is a more trouble-free process. The product. Maintenance-free battery In addition to maintenance-free, this kind of battery's anti-vibration ability is better than ordinary battery, but the price is relatively more expensive. In addition, its overall lifespan does not exceed that of ordinary lead-acid batteries. Therefore, the overall cost of use will be slightly higher than that of ordinary lead-acid batteries. In addition, there is a legend that the maintenance-free low-temperature discharge capacity of lead-acid batteries is not as strong as ordinary lead-acid batteries, but it is impossible to judge whether it is true or false at present. ◠Wind-up lead-acid battery Winding lead-acid batteries may not have been heard by many people, and the biggest difference between them and ordinary lead-acid batteries is a different structure, spiral wound internal spiral structure, and ordinary battery is flat plate structure. It has the characteristics of large starting power, long service life, small self-discharging for quick charging, strong anti-vibration and strong impact. Can work in the temperature range of minus 55 degrees Celsius to 75 degrees Celsius, and its internal structure is all solid, so the shock resistance is very strong, can withstand four times stronger than ordinary battery vibration. Wind-up lead-acid battery Its internal structure is spiral, and the electrolyte is all adsorbed by the battery separator, there is no flowing liquid, so even if it is inverted, it can be used normally. In addition, the wound-type battery can output three times more current than a normal battery, which is very suitable for use in winter cold start. In addition, the self-discharge of the wound storage battery is very small, and it can be started even if the battery is fully charged for a year or two. This is beyond the reach of an ordinary battery. Although the performance of the wound-type battery is impeccable, the price is too expensive. At present, it is only used in some high-end passenger cars, and the truck load is almost negligible. However, if you have special needs, you can also consider replacing the ordinary battery with a roll-type, as long as you can accept its high price. ◠Summary In general, the most suitable for us now is the old ordinary lead-acid battery, although it has its own shortcomings. However, the current lead-acid battery market is a mixed bag, with fake and shoddy products flooding the market. It is not easy to buy genuine products. Here, I suggest that you try to buy some well-known brand products from a good reputation dealer. ◠Postscript Since October, most parts of the northern part of the country have entered the autumn season. The strong winds and cold air have once again set the minimum temperature since the beginning of autumn this year. Temperatures in some areas have fallen below zero and even snowfall has occurred. In order for your car to have very good reliability in a cold environment, it is imperative that you do the relevant inspections and preparations in advance to ensure that it is perfectly safe.
