Remove the battery from the vehicle before charging.
Use a charger or charger to charge. Charge the battery with a current equal to 0.1 of the battery capacity until the density of the electrolyte increases within 4 hours.
It is not recommended to use a high current for fast charging of the battery, as in this case the plates may warp due to overheating.
During battery charging, the temperature of the electrolyte should not exceed 37.8°C.
