How to buy lead-acid batteries? Maintenance-free battery use and maintenance matters

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, especially to check whether the product body has a prominent mark, and pay attention to whether the production 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 the battery without the 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 branded batteries from well-known companies and large companies. Batteries are generally supplied by professional battery manufacturers. The quality of batteries produced 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 conducive to prolonging the service life of the battery. The use and maintenance of maintenance-free batteries should pay attention to the following points: 1. Do not over-discharge the batteries during use, and charge the discharged batteries in time. 2. If the vehicle is not used for a long time, the battery should be removed or the negative lead of the battery should be disconnected. When the battery is left out of use, it should be fully charged and the battery status should be checked frequently. When the voltage is low, recharge in time. 3. It is forbidden to test whether the battery has electricity by short-circuiting the battery. 4. Frequently check whether the connection part is firm and the terminal surface is clean to ensure good contact. 5. The battery vent hole should not be blocked, and it should be prevented from being sealed by ice water in winter, otherwise the internal pressure of the battery will increase and a shell burst accident will occur. 6. It is strictly forbidden to place metal tools and conductive objects near the battery terminals to prevent metal objects from colliding with the two poles of the battery, causing short-circuit and ignition, and burning the battery and terminals.
