Should new batteries be charged or discharged first? And how to charge it?

Many owners don't know how to charge new batteries after they have just changed their batteries. There are many ways to charge new batteries, but what is the most correct way?

For the first time, there is no need to recharge the batteries of the new electric vehicle. Never run out of power, which will have a great impact on the battery life. The first three charges should not exceed 12 hours. Under normal conditions, electric vehicles (not often with people, not climbing all day), when the remaining battery charge between 30% and 50%, can avoid the phenomenon of early capacity loss of batteries, but also can avoid over discharge.

If you often take people and climb hills, it is recommended that the remaining electricity can be charged at 50%. If you usually turn on very little, 60% - 70% of the battery power is not used in a week. It is recommended to charge it once. If you don't go out or stay away for a long time, it is recommended to recharge once a month. Charging time should be controlled in about 8 hours. Charging can be stopped 1-2 hours after the indicator lights of the charger change from red to green, so that the charging process is completed.

After half a year of battery use, it is better to discharge the battery deeply once a month, then charge the battery for the electric vehicle, the time is controlled in 12 hours. This will be of great benefit to the recovery of electric vehicle batteries. When the battery's power is greatly reduced or the charger of the electric vehicle does not turn the lamp when charging, it is necessary to add distilled water to the battery in order to improve the service life of the electric vehicle battery.

It's right to recharge batteries regularly. Basically, it means recharging batteries every day after riding. But here's the problem. If your battery can run 30 kilometers, run 5 kilometers or 10 kilometers, recharge it. That's not necessarily good for batteries, because when the battery is full of electricity, there will definitely be gas overflow, and this gas is the decomposition of water in the electrolyte. Raw, this water loss will occur, frequent charging, the number of water loss batteries will increase, batteries will soon enter the expiration period.

So the good way is if you don't ride an electric bike the next day, you'd better charge it up, but when you ride 5 or 10 kilometers, the next day's ride is enough, and you'd better recharge it after the next day's ride, so that the water loss of the battery will be reduced, and the battery life will be prolonged.

In addition, some batteries can run about 30 kilometers, but when they ride about 7 or 8 kilometers a day, it is better not to wait for the third or fourth day to recharge the batteries completely, but to recharge the batteries when less than half of the battery's power is left, because the batteries are easily vulcanized when the power is insufficient.

Finally, when charging, plug in the plug at the battery end and then connect 220V. At the end of charging, first pull out 220V power, then pull out the plug at the battery end. When the charger turns green, it can be charged for another hour or two. The battery is already full. It can not be charged overnight, which will cause serious damage to the battery.

From full discharge to first undervoltage protection, a 100% complete discharge can be achieved. According to the discharge degree, the battery can be divided into the following grades:

0% < shallow discharge < 30%.

30% normal discharge < 80%.

80%<Deep Discharge<100%

100%<over-discharge (over-discharge occurs when riding after the first under voltage protection occurs)

Over discharge can cause fatal damage to batteries, so it is necessary to avoid the occurrence of over discharge in the process of using electric vehicles.
