This article aims to decode and simplify battery names, from the battery experts at Yuasa, and other publicly available resources.

Understanding Yuasa Battery Naming Conventions

Battery names are not random; they follow specific conventions that can indicate everything from the manufacturer to the battery's performance characteristics. Knowing how to read these names helps in selecting the right battery for your needs.

Yuasa, a leading battery manufacturer, uses a specific structure for its battery names. For instance, the initial letter 'Y' denotes Yuasa. Understanding these codes can simplify the process of identifying the right battery.

Decoding the Numbers: Battery Council International (BCI) Standards

The numerical component in a battery name typically indicates the size of the case. For example, in a battery name like "YTX 14 A H L–BS–1," the number "14" corresponds to the case size.

BCI is a trade association that sets standards for battery specifications, including dimensions, terminal types, and performance characteristics. Understanding BCI standards is helpful for ensuring compatibility and optimal battery performance.

The numbers in the Yuasa Battery names are case size information, and use the following from BCI:
