本欧洲标准适用于标称电压为12 V的铅酸蓄电池，主要用作内燃机起动、照明以及内燃机车辆辅助设备的电源。这些电池通常被称为“启动电池”。标称电压为6 V的电池也包括在本标准的范围内。对于6V电池，所有参考电压需要除以2。包含以下内容:BS EN 50342-1:2015+A1:2018

This European Standard is applicable to lead-acid batteries with a nominal voltage of 12 V, used primarily as a power source for the starting of internal combustion engines, lighting and also for auxiliary equipment of internal combustion engine vehicles. These batteries are commonly called "starter batteries". Batteries with a nominal voltage of 6 V are also included within the scope of this standard. All referenced voltages need to be divided by two for 6 V batteries.Incorporates the following:BS EN 50342-1:2015+A1:2018
