How to Replace a Car Battery Without Power Interruption?
1 Answers
Connect the old and new batteries in parallel before removing the old battery, disconnect its wiring connected to the car, then connect the corresponding wiring to the new battery, install the new battery, and remove the jumper cables. Below is 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. Car batteries typically refer to lead-acid batteries, which are mainly made of lead and its oxides with sulfuric acid solution as the electrolyte. The normal service life of a car battery varies from 1 to 8 years, largely depending on the vehicle's usage conditions. 2. Battery Replacement: If the battery is dead, it is recommended to first measure the battery voltage. If using a multimeter, measure the battery voltage during engine cranking. You can initially use a high-frequency discharge machine or battery tester for measurement. Under a load current of no less than 110 amps, the minimum voltage should not be lower than 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 within 5 seconds, rapidly dropping to 0 volts or close to 0 volts, it suggests a possible battery fault that may require replacement.
