This Yuasa YT4B-BS motorcycle replacement power sport battery is a Dry Charge AGM. The manufacturer stock code is YUAM62T4B. The battery will arrive with instructions and a bottle of acid. Once activated (by filling, charging and sealing) it will become just like a factory activated sealed AGM power sport battery. Many of these Dry Charge AGM batteries have a 'BS' appended to the part number which stands for Bottle Stock.
With few expections Yuasa Battery, Inc. is the original equipment manufacturer (OEM) of most all power sport battery applications. In fact Honda has been using Yuasa's batteries since 1979 and other major bike and power sport manufacturers such as Harley-Davidson, Kawasaki, Cannondale, Buell, and Polaris Victory, to name a few, have followed suit. This brand is used as the standard for which all other aftermarket replacement batteries must match. Some replacements of the YT4B-BS may have higher CCA or AH while others may be slightly lower when comparing those specifications. All should match the dimentions closely and must match voltage and polarity exactly.
This motorcycle battery is 12V and has 20 CCA and 2.3 AH. It comes with a full 12 Mo. replacement warranty. Yuasa branded batteries are made either in Taiwan or the United States. Currently the YT4B-BS is made in Japan.
