What kind of common sense of purchase and use of lead-acid batteries?

1. Check whether the product logo is complete. Including the name of the manufacturer, product specifications, date of manufacture, trademark; check whether the internal and external signs are consistent, in particular, check whether the product body has a prominent mark, and pay attention to whether the processing date is in the near future. 2. Pay attention to the appearance of the battery. Check for deformation, cracks, scratches and traces of liquid leakage. The battery terminal should be clean, free from rust, and the mark should be clear. 3. Pay attention to the marked rated capacity of electric vehicle battery products. The larger the rated capacity of the battery, the longer the battery discharge time. It is best not to buy a battery without a rated label, but pay attention to whether it is dedicated to electric vehicles. If there are multiple capacity labels, the rated capacity shall prevail. 4. Buy brand-name batteries from well-known companies and large companies. Batteries are generally supplied by professional battery processing factories, and the quality of batteries processed by different brands and different manufacturers is different, and the price is also different. Well-known, large-scale companies have large scale, strong technology, good after-sales service, and battery quality is guaranteed. 5. Purchase an intelligent charger with automatic control that is matched with the battery. A suitable charger can automatically adjust the charging size and time, which is beneficial to prolong the service life of the battery. Use common sense 1. When using, it is best to use a human-powered assisted vehicle to start when the electric vehicle starts and goes uphill against the wind. When the simple electric vehicle is started, uphill, and riding against the wind in strong winds, pedal assistance should be used to reduce The battery load extends its life; the luxury electric vehicle should be started slowly when starting, and should not be turned to the end to accelerate rapidly; and when going downhill, the steering wheel of the electric vehicle can be released. When the battery is insufficient, you should ride at a lower speed; no matter when, you should not ride electric under the undervoltage state. 2. When using an electric bicycle, never overload it. Generally, the design load of an electric bicycle is 75kg, that is, single rider, overloading will cause the battery to discharge with high current for a long time, thereby damaging the battery, which is an important reason for the shortened battery life. 3. It should be noted that the capacity of the battery changes with time and environment. Generally speaking, as the number of uses increases, the battery capacity will gradually decrease. In the case of low temperature, the battery capacity will also decrease, and it can be restored when the temperature rises. 4. Master the correct charging method. The ambient temperature of the battery should be between 0～40℃, and the charging should be carried out at room temperature. Pay attention to the charging status of the charger and the normal charging time to prevent the battery from undercharging or overcharging. If abnormal charging is found, you should consult a professional in time to avoid damage to the battery. Charge it in time after use, it is best to charge it every day, such as driving more than 20 kilometers at a time, it is best to charge in time and do not wait for the battery to be completely used up before charging. If the battery is left unused for a long time, recharge the battery on time. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
