4. Frequently Asked Questions
Q1: Why must the positive terminal be connected first?
Current transmission requires a complete loop, and the positive connection can establish a stable potential difference to avoid sparks. Experimental data shows that the risk of sparks increases by 47% if the negative electrode is connected first.
Q2: Can automatic transmission vehicles be hooked?
It can be operated but special attention is required: ① It must be in P gear ② The power supply vehicle must have a comparable displacement ③ It is recommended to give priority to the emergency power supply.
Q3: Does the battery need to be replaced after hooking up the car?
Determine based on the test results: if the voltage is <11.8V, it needs to be charged and tested. If it is still <12.4V after charging, it is recommended to replace it. The probability of battery failure over 3 years is 62%.
