Which is better, a billion water battery or a dry battery?

Billion energy water battery and dry battery have their own advantages and disadvantages. Each has its advantages and disadvantages. Advantages of water storage battery: strong instantaneous large current discharge capacity, high power and strong load capacity. Disadvantages of water storage battery: poor endurance, poor deep discharge ability and poor deep cycle life. Dry battery is a maintenance-free battery. Maintenance-free battery consumes very little electrolyte due to its own structural advantages, and basically does not need to replenish distilled water during its service life. It also has the characteristics of impact resistance, high temperature resistance, small volume and small self-discharge. The service life is generally twice that of ordinary batteries. water battery

be

A lead-acid battery. Because there is a lot of liquid in the battery, it is usually called "water battery". The liquid in the water storage battery is easy to lose and needs to be replenished frequently, so it is also called a maintainable battery. This kind of battery is mostly used in automobiles, and its discharge current is relatively large.
