What Happens If Car Battery Cables Are Connected Incorrectly?

[McMaya]

If the battery cables are connected incorrectly, not only will the wiring and connectors be damaged, but it will also affect the lifespan of the electrical circuit and may even cause a short circuit leading to a fire. Here is some relevant information about car batteries: 1. Battery: A battery, also known as a storage battery, is a device that converts chemical energy into electrical energy. The car battery referred to here is a lead-acid battery, which is primarily made of lead and its oxides, with sulfuric acid solution as the electrolyte. The normal service life of a car battery ranges from 1 to 8 years, depending largely on the condition of the vehicle. 2. Battery Replacement: If the battery is dead, it is recommended to first measure the battery voltage. If using a multimeter for inspection, measure the battery voltage while cranking the engine. You can start by using a high-frequency discharge meter or a battery tester to measure it. Under a load current of no less than 110 amps, the minimum voltage should not drop below 9.6 volts and should remain stable for 5 seconds. If the voltage is below 9.6 volts but remains stable for 5 seconds, it indicates over-discharge, and the battery should be recharged promptly. If the voltage is below 9.6 volts and cannot remain stable for 5 seconds, dropping rapidly to 0 volts or close to 0 volts, it suggests a battery malfunction, and replacement may be necessary.
