BYD has announced another important strategy after announcing the discontinuation of fuel cars, announcing that it will be the first to phase out lead-acid batteries and fully use lithium iron phosphate starter batteries, which is also of epoch-making significance. BYD's lithium iron phosphate starter battery has a long life, up to more than 3000 cycles, which is equivalent to the same life as the whole car, almost no need to replace for life, which is lower in cost than lead-acid batteries.
The replacement cost of lead-acid batteries is 400-600 yuan, with a life span of 2-3 years, short life, easy to lose electricity, and heavy weight. Most importantly, lead as raw material, health hazards and environmental pollution problems have begun to emerge.
