Long term non use requires charging, short-term parking requires power outage The normal self discharge of a battery is caused by structural factors of the battery itself, such as impurities in the electrolyte or partial detachment of active substances inside the battery, which settle at the bottom and discharge the positive and negative plates through precipitation. If the battery is not used for a long time, it will slowly discharge on its own, so the car should be started every once in a while to charge the battery. Cardholders need to disconnect the main power switch every time they receive their cars. If the storage time exceeds one month, the battery needs to be removed for recharging. Observe the driving voltage and check the generator for low voltage Pay attention to the reading on the voltmeter while driving. The normal voltage range is 27.6-28.8V when the engine speed is between 1100-1400rpm. If the voltage is lower than the standard value, it will affect the charging of the battery. Check and repair the generator and charging line at the station: ① Check the generator fuse and output circuit ② Check the generator and generator belt ③ Check the indirect cables between the engine and the frame Long term insufficient charging of batteries can shorten their lifespan What should I do if the instrument is normal but still lacks power? When the engine speed is between 1100-1400rpm and the vehicle voltage is within the range of 27.6-28.8V, it indicates that the generator output is normal. If the battery still frequently runs out of power, the problem may be a decrease in the capacity of the battery itself or a problem with the battery cable connection (such as poor contact). Keep the engine running at medium speed, check the voltage between the positive and negative terminals of the battery, and compare it with the indicated voltage on the instrument panel. If the two are very close, it indicates that the wiring connection between the battery and the vehicle is normal. Frequent power loss may be due to a decrease in battery capacity, and the battery needs to be checked or replaced. If the voltage between the positive and negative terminals of the battery is significantly lower than the vehicle voltage indicated by the instrument panel, it is necessary to check whether there is poor contact (such as rust) between the battery cable and the vehicle connection, and if necessary, disassemble the cable for repair.
