lead-acid batteries have strict requirements on ambient temperature and ventilation, and harsh environments will greatly shorten their service life. The suitable working temperature is 10-30℃. In summer, avoid direct sunlight and closed high-temperature operation to prevent bulging and liquid leakage caused by excessive internal pressure. In winter, low temperature reduces battery activity and charging efficiency, so appropriately extend charging time and avoid high-power discharge in extremely cold environments. Keep the usage area well-ventilated to dissipate tiny gas released during operation. Stay away from corrosive gases and organic solvents, and maintain a safe distance of more than 0.5 meters from heat and spark sources.
