There are several batteries! Which one is the best?

Maintenance-free lead-acid battery is actually an upgraded version of an ordinary lead-acid battery. It has a fully enclosed shell structure and does not need to be maintained when used. This eliminates the need for ordinary batteries to often supplement distilled water. It is a relatively convenient product.

Analysis of the advantages and disadvantages of which three kinds of lead-acid batteries

Maintenance-free battery

In addition to being maintenance-free, the battery is also better at vibration resistance than an ordinary battery, but it is also relatively more expensive. In addition, its overall life does not exceed that of ordinary lead-acid batteries, so the overall cost of use will be slightly higher than that of ordinary lead-acid batteries. In addition, there is also a legend that the low-temperature discharge capability of maintenance-free lead-acid batteries is not as strong as that of ordinary lead-acid batteries, but it is currently impossible to judge.

Twisted lead acid battery

The coiled lead-acid battery may not have been heard by many people. The biggest difference between it and ordinary lead-acid batteries is that the structure is different. The coiled interior is a spiral structure, while the ordinary battery is a flat plate structure. It has the characteristics of high starting power, long service life, small self-discharge, strong shock resistance and impact. It can work normally in the temperature range from minus 55 degrees Celsius to 75 degrees Celsius. In addition, its interior is an all-solid structure, so its vibration resistance is very strong and it can withstand vibration four times stronger than an ordinary battery.

Winding lead-acid battery

Its internal structure is spiral, and the electrolyte is all adsorbed by the battery partition, and there is no liquid flowing, so even the inverted state can be used normally. In addition, winding batteries can output three times more current than ordinary batteries, which is very suitable for cold start in winter.

In addition, the self-discharge of the winding battery is very small, and it can be stored for a year or two after it is full of electricity and can even start the vehicle. This is beyond the reach of ordinary batteries. Although the performance of the winding battery is impeccable, the price is really too expensive. Currently, it is only used in some high-end passenger cars, and the use of trucks is almost negligible. However, if you have special needs, you can also consider replacing ordinary batteries with windings, as long as you can accept its high price.

Summary

Taken together, the most suitable for us at present is the ancient common lead-acid battery, although it has its own shortcomings. But the current lead-acid battery market is mixed, fake and shoddy products filled the market, it is not easy to buy the real product. Here I suggest that you try your best to buy some well-known brand products at a dealer with better reputation, which is relatively more reliable than street stalls.

Quotations

Since October, much of the North has entered the late autumn season, with strong winds driving the cold air back and forth to its lowest temperature since autumn, with temperatures already below zero in some areas and even snowfall. In order for your car to be very reliable in a cold environment, it must be checked and prepared in advance to ensure that it is foolproof.

In general, electric vehicle batteries are mainly divided into two types, one is based on lithium batteries, the other is lead-acid batteries, and of course there are nickel-metal hydride batteries, solar cells and other new energy batteries. Ranked close to the top, such as Tianneng Weifu Haibao Shuangdeng.

Here are a few tips for maintaining your battery:

1, is strictly forbidden to store battery power loss at the time of storage is strictly forbidden to be in the state of power loss. Loss of power means that the battery is not charged in time after use. Storage of batteries in a deficit state is prone to sulfuric acid salinization, lead sulfate crystals adhere to the polar plate, blocking the ion channel, resulting in insufficient charging and reduced battery capacity. The longer the power loss is idle, the more damaged the battery will be. When the battery is idle, it should be recharged once a month. This will keep the battery in good health. Don't think that the electric car will not be used.

(2) During the periodic inspection, if the range of the electric vehicle suddenly drops by more than ten kilometers in a short period of time, it is very likely that at least one cell in the battery will have a broken grid, a softening of the polar plate, and a shedding of the active material of the polar plate. Note that once the problem is found, it should be checked, repaired or assigned to a professional battery repair agency in a timely manner. This can extend the battery's life relative to the maximum savings. 3, avoid large current discharge electric vehicles in the start, manned, uphill, please use pedal help, as far as possible to avoid instantaneous large current discharge. European electric vehicle maintenance staff said that high current discharge can easily lead to lead sulfate crystals, thus damaging the physical performance of the battery plate.
