What are the deep cycle AGM battery capacity and influencing factors

The amount of electrolyte in the deep cycle AGM battery is small, the thickness of the electrode plate is thick, and the utilization rate of active materials is lower than that of the open-type deep cycle AGM battery, so the discharge capacity of the deep cycle AGM battery is about 10% lower than that of the open-type deep cycle AGM battery. Compared with today's gel-sealed batteries, its discharge capacity is smaller.

What is the capacity of the deep cycle AGM battery?

The capacity of a deep cycle AGM battery refers to the amount of power output by the deep cycle AGM battery within the permitted range of discharge, including the following two aspects: 1. Rated capacity: a fully charged deep cycle AGM battery, when the electrolyte temperature is 30°C, continuously discharges at a current of 20h discharge rate when the specified stop voltage is reached, the power output by the deep cycle AGM battery is the rated capacity. 2. Starting capacity: the starting capacity is the power supply capacity of the external deep cycle AGM battery when connected to the starter. At the same time, it is divided into normal temperature starting capacity and low-temperature starting capacity according to the conditions of use. The starting capacity at room temperature refers to the output capacity of the deep cycle AGM battery when the deep cycle AGM battery is continuously discharged to 9V with a current at a discharge rate of 5 minutes when the electrolyte temperature is 30°C. The low-temperature starting capacity refers to the output capacity of the deep cycle AGM battery when the electrolyte temperature is -18°C, with a current of the discharge rate of 5 minutes when the deep cycle AGM battery is continuously discharged to 6V.

What are the factors that affect deep cycle AGM battery capacity?

The larger the capacity of the deep cycle AGM battery, the more electric energy it can save. The size of the deep cycle AGM battery capacity is closely related to the discharge current, the density of the electrolyte, and the structure of the plate. Any type of deep-cycle AGM battery will have a capacity decline in a low-temperature environment. For example, deep cycle AGM battery cars and electric cars will experience reduced mileage due to low temperatures, and the deep cycle AGM battery life of electronic devices will not be exceptionally reduced. The reasons for this phenomenon are rough as follows. ①When the discharge current becomes larger, the terminal voltage and capacity of the deep cycle AGM battery will decrease; ②The lower the temperature, the capacity of the deep cycle AGM battery will also decrease. The rated capacity is tested at 30℃; ③The electrolyte density increases, which can reduce the internal resistance and increase the capacity, but not too much; ④Increase the area and the number of plates to increase the capacity. The selection of thin plates increases the number of plates, which can increase the capacity of the deep cycle AGM battery without enlarging the volume of the deep cycle AGM battery.
