In the aftermarket, your Yuasa YTX20L battery (also known by stock code YUAM420BS) can be replaced with comparable brands that meet or exceed the standards set by Yuasa Battery, Inc.
Yuasa is the #1 original equipment manufacturer of batteries for motorcycles, ATV's, motor scooters, snowmobiles and personal watercraft. This factory activated (FA) battery, despite being the most widely used sizing (it has six variations; 10 if you count opposite polarity versions!) surprisingly was Original Equipment (OE) in a small handful of applications. The Yuasa Battery Applications & Specifications book indicates both Buell (X1 Lightning) and Harley Davidson (VRSC V-Rod) specify the FA sealed AGM was OE. BRP’s Can-Am Commander, Outlander and Renegade as well as a plethora of Bombardier Ski Doo all utilize the FA version.
Impact Battery has replacement batteries that compare favorably on all or some of the most important metrics including price, CCA, AH, warranty and location of manufacture.RIGHT_SIDEBAR_CONTENT

Does This Motorcycle Battery Come With Acid in a Bottle?
No, the YTX20L is a factory sealed AGM that arrives fully charged and ready to install. The -BS dry charge version comes with electrolyte in a plastic container. The BS stands for bottle stock or bottle supplied electrolyte. The buyer would use the temporarily exposed battery cell openings to puncture and empty the specially designed bottle of acid into the battery prior to charging and installing.
