The battery of the stroller must not be in a dead state. The stroller is often used for charging and discharging, which can increase the life of the battery, and it is best to charge it once every half month or one or two months.
When the stroller is playing, try not to wait for the battery to die before recharging, which will lead to excessive oxidation of the lead acid of the battery and greatly reduce the storage capacity. Generally, one-third of the battery power is left to charge. When charging the battery, it should be charged in a cool, ventilated place away from open flames (when connecting the charging plug, be sure to pay attention to whether the insulation near the socket end is damaged), so as to provide a good heat dissipation environment for the battery, and do not charge it after exposure in the hot sun to avoid hydrogen explosion.
