Can car battery be repaired without electricity?

Car batteries can usually be repaired if they are not charged, but the specific situation needs to be analyzed. When the battery does not store electricity, the first thing to do is to identify the reasons behind it. If the electrolyte is insufficient, it can be filled with distilled water or pure water; if the voltage is insufficient, it can be raised with the help of the repair instrument; if the electrode is vulcanized, it may not be repaired, and the battery needs to be replaced. Different reasons correspond to different repair methods, only by accurately judging the problem, can we effectively solve the problem that the car battery does not store electricity. When it is determined that the battery is not charged due to insufficient electrolyte, it should be noted that only distilled water or pure water can be added to the battery, and tap water must not be used, because impurities in tap water may affect the performance of the battery. If the battery voltage is detected to be insufficient and lower than 11 V, the high resistance repair function of the repair instrument can be used to increase the voltage to above 11 V. However, if the battery voltage is lower than 10 V, even after charging and repair operations, the voltage can not be increased, then the battery will probably need to be replaced. The situation of electrode vulcanization is relatively difficult, once the electrode vulcanization occurs, it usually can not be repaired, only a new battery can be replaced. In addition, battery aging is also a common factor leading to no electricity, when the battery service life is more than three years, it is likely to have reached the service life, direct replacement may be a better choice. In addition to these repair methods and replacement situations, the daily maintenance of automobile batteries is also crucial. When the car is parked for a long time, it will cause battery power loss or even damage, so the battery electrode line should be pulled out for a long time, and try not to stop the car for more than 10 days. If it needs to be parked for a long time, it is better to start the car every 5 days or so and keep the engine idling to charge the battery. At the same time, the electrical appliances in the car should be turned off in time after the car is turned off, so as to avoid the battery running out of power for a long time and frequently. In short, it is not impossible to solve the problem that the car battery does not store electricity. Through correct judgment and appropriate repair methods, the battery can be restored to normal operation in many cases. But at the same time, we should also pay attention to daily maintenance, reduce the probability of battery problems, extend its service life, and keep the power system of the car in good condition.
