What could be the issue when the Baojun 630 fails to start?

[OMaximus]

Baojun 630 failing to start could be due to: 1. When starting, only the electromagnetic switch of the starter makes a 'clicking' sound, or during the first attempt, the starter slowly turns the crankshaft a few times, followed by the electromagnetic switch clicking again, but the crankshaft does not rotate. This phenomenon is usually caused by a 'broken grid' fault in the battery. 2. The car starts every time after a temporary stop, but when parked for a longer time or the next day, it only manages to turn the crankshaft once. This indicates severe self-discharge of the battery, with its plates and separators heavily aged, suggesting the battery is nearing the end of its life. 3. If the starter suddenly lacks power during startup, accompanied by a burning rubber smell or smoke from the battery area, it is mostly due to poor contact at the terminal posts or clamps, leading to overheating and damage.
