1）Choice of charging environment
Because lead-acid batteries contain electrolytes, once the temperature drops, the batteries will freeze, causing irreparable damage such as battery plate cracking, shattering, and battery casing bulging. Therefore, it is best to choose a garage for charging.
2）After charging, it can be float charged for another 1 hour
The charging time is controlled at about 8-10 hours. Since the charging efficiency will be reduced in low temperatures in winter, the charging time can be appropriately increased to allow the electric car to run further.
