Lead acid battery maintenance tips

1. Do not replace the charger casually. Do not remove the speed limit of the controller.

If the user has a longer mileage requirement, and multiple chargers are provided for charging off-site, the charger that supplements the charging during the day is supplemented with a charger, and the original charger is used at night. Removing the speed limit of the controller, although it can improve the speed of some cars, in addition to reducing the safety of the car, it will also reduce the battery life.

2. Protect the charger.

The general instructions for use have instructions for protecting the charger. Many users do not have the habit of reading the manual. They often think of looking for the manual after the problem. It is often too late, so it is very necessary to read the manual first. In order to reduce the cost, the current chargers basically do not have a high vibration-resistant design, so that the charger is generally not placed in the trunk and basket of the electric bicycle. In special cases, it must be moved, and the charger should be packaged in foam to prevent bumps. After many chargers are vibrated, their internal potentiometers will drift, causing the entire parameters to drift, resulting in an abnormal state of charge. Another thing to note is that the charger should be kept ventilated during charging. Otherwise, it will not only affect the life of the charger, but also cause thermal drift and affect the state of charge. This will cause damage to the battery. Therefore, it is very important to protect the charger.

3. Charge every day.

Charging every day, so that the battery is in a shallow cycle, the battery life will be extended. The memory efficiency of lead-acid batteries is not so strong, and often the discharge of electricity has a greater impact on the life of the battery. Most chargers may charge 97% to 99% of the battery after the indicator light is fully charged. Although only undercharged 1% to 3% of the power, the impact on the continuation ability is almost negligible, but it will also form undercharge accumulation, so after the battery is fully charged, it will continue to float as much as possible, to suppress the battery vulcanization. beneficial.

4. Charge in time.

After the electric vehicle battery was discharged, the vulcanization process began. At the beginning of 12 hours, obvious vulcanization occurred. Timely charging can remove non-severe vulcanization. If not recharged in time, these vulcanized crystals will accumulate and gradually form coarse crystals. The general charger is powerless to these coarse crystals, which will gradually reduce the battery capacity and shorten the capacity. Battery life.

5. Regular deep discharge.

Regular periodic discharge of the battery also facilitates "activation" of the battery, which can slightly increase the capacity of the battery. The general method is to periodically discharge the battery completely. The method of full discharge is to ride to the first undervoltage protection under normal load conditions on a flat road. Note that we place special emphasis on the first undervoltage protection. After the battery is under the first undervoltage protection, after a period of time, the voltage will rise and return to the non-undervoltage state. If the battery is used again, the battery will be seriously damaged. After the complete discharge is completed, the battery is fully charged. Will feel the battery capacity has improved.

6, develop some good habits of saving electricity.

Use sliding as much as possible. When using the following slopes, use the early power-off slide to reduce the speed as much as possible. When you are about to encounter a traffic light, enter the taxi ahead of time to minimize the brakes. A friend told me that he would rather reduce the brakes once more in the bay. This makes sense. When starting up, it is best to add riding assistance, not only can increase the starting speed, but also reduce battery power loss and life damage.

7, pay attention to the charging environment.

The best ambient temperature for charging is 25 °C. It is best to arrange the battery and charger in an airy and temperature-controlled environment. It is especially pointed out that when the battery enters the warm room in the outdoor low temperature in the north in the winter, frost condensation will appear on the surface of the battery. In order to avoid leakage of the battery caused by frost condensation, it should be charged after the battery temperature rises to be close to the room temperature and dried.

8, regular maintenance of the battery

Regular maintenance of the battery can reduce damage to the battery. The repair of the state of charge of the battery can alleviate the "battery behind" failure, which is a breeze for dealers equipped with maintenance capabilities. For water loss, when the battery capacity is 70%, the hydration effect is better than the battery capacity of 40%. Even some brands of products have suggested that not going through the prescribed time is equivalent to giving up the warranty period of the battery. Consumers are subject to losses that should not occur.
