Is it possible to charge the maintenance free battery outdoors in winter?

It can be charged outdoors, nothing too much attention, it is best to charge it once when it is not used for a period of time, maintenance-free as the name suggests is that it does not need to be maintained Normal use is good If it is not used for a long time, it is best to replenish the battery once in two months Maintenance-free battery is the most taboo high-current charging It will cause the battery to be scrapped directly due to lack of water, and there are currently two main types of batteries used in the car, one is the lead-acid battery with electrolyte, and the other is the maintenance-free battery. The service life of an automobile battery not only depends on the structure and quality of the battery, but also is closely related to its operation and maintenance. Generally, the service life of automobile batteries is about 2 years, if properly maintained, it can reach 3 to 4 years, and if it is installed with a desulfurization device lead-acid battery capacity restorer, it can even reach more than 6 years.

It is very necessary to maintain the battery once during the change of seasons.

The maintenance-free battery does not need to add distilled water and adjust the concentration of the electrolyte, it is fully sealed, and there is generally no electrolyte spilling to the surface of the battery. Its maintenance is very simple, mainly to check whether there is any leakage, clean the surface dirt, treat the oxide of the positive and negative pole piles, fasten the clips of the two pole piles and observe the color of the battery eye. The color of the electric eye is green, which means that the battery is sufficient; Black is insufficient power and needs to be recharged; Gray or light yellow means that the electrolyte is insufficient, because the maintenance-free battery cannot be filled, the battery should be replaced immediately.

The car that has not been used for a long time should be started every 25 days or so, and the medium speed should be controlled by the hand throttle for about 20 minutes, otherwise the release time is too long, and the battery will cause serious vulcanization of the plate after the loss of power after discharge, and the car will not be able to start when the car is used. For example, frequent short-distance driving will lead to insufficient battery charging, and long-term power loss, resulting in plate vulcanization, and early termination of battery life. Should run a small long distance regularly to fully charge or regularly remove the battery to be fully charged, if the installation of desulfurized lead-acid battery capacity restorer, the battery capacity and life will be more guaranteed,.

When removing the battery from the car, the negative electrode should be removed first and then the positive electrode, and the opposite should be done when installing.

Do not replace the car with a larger battery capacity than the original battery, because the generator power generation on the car is fixed, and the power generation will not increase, such as replacing the battery with a large capacity will make the new battery undercharged, and the car can not start smoothly, and the long-term loss of the battery will lead to serious vulcanization of the plates and faster deterioration.

When starting the car, the starting time is not more than 3 to 5 seconds, and the interval between starting again is not less than 15 seconds.

Maintenance and care of the battery:

1) When the red undervoltage indicator light on the dashboard glows, it indicates that the power has entered the starvation zone and should be charged in time. Timely charging will greatly extend battery life. A full charge of the battery should be carried out once a day, and the charging time should be 8-12 hours each time, so that the battery can be kept in a state of abundant power at any time, which is of great benefit to its life.

If you do not charge it in time after riding, it will greatly affect the service life of the battery, and the battery will be scrapped due to serious conditions;

2) When the electric bicycle starts, it should accelerate slowly; On the steep road surface and when driving against the wind, it is best to pedal to assist to avoid high-current discharge of the battery, so as to prolong the life of the battery and the motor, and avoid burning out the electrical components;

3) When the battery is not used for a long time, it should be stored with sufficient power, and the battery should be replenished and charged no less than once a month;

4) The battery should be charged in an environment with good air circulation. Avoid near the fire source, and it is best to remove the battery pack when charging to facilitate heat dissipation;

5) The battery is at the optimal working ambient temperature of 15 -40 °C. Outside this temperature range, it will affect the normal operation of the battery;

6) Do not make the positive and negative ends of the battery short circuit, so as to avoid danger;

7) Only use the special charger provided by the manufacturer for charging;

8) The battery is a special battery, please do not use it as a power source other than the electric bicycle, so as not to cause damage to the battery;

9) Do not use organic solvents to clean the battery shell. In the event of an accidental fire, carbon dioxide should not be used to extinguish the fire, but a fire extinguishing appliance such as carbon tetrachloride should be used;

10) If the accumulator group fails, please send it to the manufacturer or the designated after-sales service point for proper handling. Please do not throw it away at will to avoid environmental pollution;

11) When the ambient temperature is higher than 40 or lower than -10, the battery life will be shortened. Therefore, when the temperature is high in summer, the battery should be protected from direct sunlight. In the case of low temperatures in winter, batteries should be stored indoors and charged indoors. After the battery is fully charged, the charge should be extended for another 2 hours;

12) When the ambient temperature is -10, the battery can only release 60% of the power. As a result, the mileage of a full charge in the winter is much less than that of a full charge in the summer. In winter, it is better to drive with foot pedal assistance when driving electrically;

13) The battery is a consumable, and the life of the battery is limited. The end-of-life period of the battery should be assessed by the fact that the mileage of a full charge can only reach half of the national regulation (25km). That is, when the mileage of a full charge is less than 13km, the battery life is terminated, and the new battery should be replaced;

14) In summer, it is strictly forbidden to expose the electric vehicle to the sun for a long time.

Problems that should be paid attention to in the use and maintenance of batteries:

1. Keep the battery fully charged.

2. Carry out regular deep discharge. It is recommended to carry out a deep discharge after two months of use.

3. It is forbidden to store the loss of electricity. The storage of battery loss will affect the service life, and if it is idle for too long, the battery will be damaged.

4. Regular inspection. The charger should also be checked for malfunction.

Hello, there is no problem this winter, as long as you don't get wet in the rain and snow, there is no problem.
