　　 2. Battery warranty time. Batteries are not like fast-moving products. Its life cycle is very long, usually about 5 years, some even longer. If quality problems occur during this period, maintenance personnel are required to perform maintenance, which is also a small expense. Therefore, the warranty time is very important.
