I often hear people say they are going to increase the size of their batteries by replacing their Group 24 batteries with Group 27s. Unfortunately they are under a misconception that group size and battery capacity are related. Group Number: Standards for automotive and marine batteries are set by the Battery Council International (BCI). They have defined Group Number for various batteries. The group number has no relationship to the capacity of the battery. It is only a grouping based on the physical outside dimensions of the battery, and whether the lugs are on the top or sides of the case. "BCI GROUP NUMBER-The BCI Group Number defines a battery by describing the following characteristics: A.) Its maximum dimensions (L x W x H) B.) Voltage (6 volt or 12 volt) C.) Post configuration D.) The type of terminal used (top, side, flag, etc.) It should be noted that the BCI (Battery Council International) Group Number does not designate a battery's capacity, it merely defines the above listed physical characteristics." The following excerpted chart shows various group numbers and their dimensions.

大小真的重要吗？

我经常听到人们说，他们将通过用27组替换24组电池来增加电池尺寸。不幸的是，他们误以为团队规模和电池容量有关。组号：汽车和船用电池的标准由国际电池理事会（BCI）制定。他们为各种电池定义了组号。组号与电池容量无关。它仅是根据电池的实际外部尺寸以及接线片位于电池盒的顶部还是侧面的分组。“ BCI组号-BCI组号通过描述以下特征来定义电池：A.）其最大尺寸（长x宽x高）B.）电压（6伏或12伏）C.）后配置D.）使用的终端类型（顶部，侧面，标志等）
