12V battery is used to start the engine in conventional car. It is used once per trip normally. In PC, the engine is started multiple time with EV on and off. So my questions are:
1. In PC, 12V battery tear and wear more than those conventional car?
2. How often 12V battery need to be changed?
3. If PC 144V battery full or half, but 12V battery is drained, can we still start the car? or can run it in EV mode only?

RM347,470).
For comparison, latest Mercedes E200 in Malaysia sold at the price of RM363,060 (extra RM15,950 only); 86 in Singapore sold at the price SGD 185,988 (extra SGD47,000 only).
Are the Singaporean PC owner crazy or what?

12V battery starts ECU. ECU decides to start the engine via motor powered by the traction battery. So the 12V does not start the engine. Unlike normal cars, the 12 V starts the engine via an electronic starter. Our PC does not require an electronic starter, so less 1 wear-prone component.
