The common models of lead-acid batteries for electric mopeds currently on the market mainly include 6-DZF-XX, 6-EVF-XX, 6-QW-XX, etc., where 6 means that it is composed of 6 single-cell batteries. The voltage of each single-cell battery is 2V, the voltage of the whole battery is 12V, DZF means a valve-regulated lead-acid battery for electric mopeds, EVF means a valve-regulated lead-acid battery for road vehicles, QW means a maintenance-free lead-acid battery for starting, XX means battery capacity, in Ah.

Among these models, the 6-DZF-XX series battery is one of the most commonly used battery types for electric moped, with the advantages of high energy density, long life, maintenance-free and other features, which can meet most of the needs of electric motorcycles. Batteries with different capacities can adapt to electric motorcycles with different driving ranges.

In addition to the selection of models, we should also pay attention to the performance indicators of lead-acid batteries. The main performance indicators include capacity, internal resistance, self-discharge rate, cycle life and so on. Capacity is an important indicator for measuring batteries. The internal resistance represents the energy storage capacity of the battery, the conductive properties and self-discharge rate determine the self-discharge rate of the battery during storage, and the cycle life represents the number of cycles of charging and discharging the battery.
