美国邱健Trojan蓄电池T-875   8V170AH采用AGM隔板

电极主要由铅及其氧化物制成，电解液是硫酸溶液的一种蓄电池。英语：Lead-acidbattery。放电状态下，正极主要成分为二氧化铅，负极主要成分为铅；充电状态下，正负极的主要成分均为硫酸铅。分为排气式蓄电池和免维护铅酸电池。

电池内压超出正常水平后，VRLA（Valve-RegulatedLeadAcidBattery即“阀控式密封铅酸蓄电池”的缩写）电池会放出多余气体并自动重新密封，保证电池内没有多余气体。

The magnitude of the internal resistance of lead-acid batteries reflects their load capacity. Under the same conditions, the smaller the internal resistance, the greater the output current, and the stronger the load carrying capacity. The internal resistance of lead-acid batteries includes the resistance of the electrode plate, separator, electrolyte, connecting rod, and pole. The electrode plate resistance is very small in a fully charged state, but as the discharge degree of the battery increases, the amount of PbSO4 covering the surface of the electrode plate increases, The resistance of the electrode plate will increase accordingly. The resistance of the separator mainly depends on the material, thickness, and porosity of the separator. Among commonly used separators, the resistance of microporous plastic separators is smaller. The resistance of the electrolyte is related to the temperature and relative density of the electrolyte. When the temperature decreases, the viscosity of the electrolyte increases, the permeability decreases, and the resistance increases. However, when the relative density of the electrolyte is too high or too low, the resistance increases
