Yuasa YUAM3RH2S or YTX12-BS Battery Replacements

The original Yuasa YUAM3RH2S / YTX12-BS battery is made in the USA. Yuasa Battery Inc. is the #1 original equipment manufacturer of batteries for motorcycles, ATV's, motor scooters, snowmobiles and personal watercraft. They are the ones that set the OE specs that all other premium brands such as Motobatt (MBTX12U), and East Penn Deka need to match. Many of these aftermarket replacement batteries often outperform originals and offer incredible value plays.

When you see the "-BS" this is a signal that the battery is a dry charge AGM battery. This means it comes with an acid bottle that the end user or dealer must use to fill the battery. You would then charge and seal the battery prior to initial installation. Most riders today prefer receiving a factory sealed AGM battery that comes fully charged and ready to use. Several brands below such as the Moto Classic, MotoBatt's MBTX12U or the ETX12 made here in the USA by East Penn will satisfy this need.

Brief Yuasa YTX12-BS History Lesson

Kawasaki, Suzuki and Triumph use this battery size in many of their motorcycles. Honda Motor Sports and Aprilia use it in a handful of their bikes and scooters. In fact, Honda was the first to use this battery size in their scooter and ATV lineup back in 1985. The FL350R ODYSSEY, TRX250 FourTrax and Recon were some of the first machines to utilize this staple in the power sport industry.

The original Battery Specs are as follows: 6.00 x 3.44 x 5.13” (L x W x H); 10 Ah; 180 CCA; 9.2 Lbs

Here is a brief competitive cross reference for the TX12 group sizing. All of these battery replacement options will have the same outer dimensions and similar specs. Universal Power Group manages the Kinetik label under part number APTX12-BS or stock code 46075. Prior to this they referred to their power sport batteries as Adventure Power and used the stock code 42032 and UTX12-BS nomenclature. Power Sonic, known better for their SLA UPS backup batteries, goes by the part number PTX12-BS. Several brands including Chrome, Moto Classic, MotoCross, and Scorpion use the YTX prefix originally put forth by Yuasa.
