Can Car Batteries Still Be Repaired?
2 Answers
Automobile batteries can be repaired when they are disconnected from power. Here is some extended information: 1. When charging a battery, it is best to remove it from the vehicle frame and keep it away from heat sources and open flames, as the charging process can easily produce flammable and explosive gases. Any slight mishandling during this operation can easily lead to an explosion. 2. For water-based batteries, it is also necessary to check the liquid level. Adding voltage when the liquid level is too low can easily damage the battery. Additionally, during the charging process of a water-based battery, the six caps on the battery must be removed to facilitate better gas venting.
Whether a car battery can be repaired depends on the specific situation. For regular lead-acid batteries, if the issue is just sulfation causing power loss, using a professional repair device to charge and discharge a few times might restore some capacity. However, if the battery has been used for three or four years and the internal plates are deformed or short-circuited, even a miracle won't bring it back. Last time I went to the auto parts market, the shop owner said new batteries now cost only three to four hundred yuan, so buying special repair equipment isn't cost-effective. Another thing to note is that if the battery casing is bulging or leaking, it's best not to bother trying to fix it—replacing it is the safest option. High temperatures in summer can accelerate battery aging, so it's important to regularly check the voltage with a voltmeter. If it drops below 12 volts, you should be on alert.
