Test items:
Appearance, polarity, size, airtightness, insulation resistance, balance of terminal voltage, capacity, high current withstand ability, short circuit current and internal resistance, overcharging resistance, charge retention ability, sealing reaction efficiency, exhaust valve action, overcharging life, safety, acid mist resistance, tilt resistance, sway resistance, vibration resistance The existence and durability of information and warning signs
Exhaust type batteries
Batteries consist of a tubular positive plate, negative plate, partition, battery compartment, battery cover, electrolyte, terminals, and acid caps. The battery compartment and battery cover should be sealed so that the gas generated inside the battery cannot be discharged from outside the acid proof cap. Each battery should have an electrolyte level mark that is easy to observe
Valve regulated battery
The battery is composed of a positive plate, a negative plate, a partition, a battery compartment, a battery cover, electrolyte, terminals, and an exhaust valve.
. The battery compartment and battery cover should be sealed so that the gas generated inside the battery cannot be discharged outside the exhaust valveBattery structure
