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.
