Yuasa introduces an absorbed glass mat (AGM) battery specifically designed to replace the conventional vented lead-acid batteries that come as original equipment in many BMW motorcycles. The Yuasa YT19BL-BS battery is an exact OEM replacement, even including the protective terminal caps that characterize the BMW OEM battery.

The Yuasa YT19BL-BS battery fits a variety of BMW motorcycle models from 1970 to 2014 model years, and engine sizes from 500 cc to 1600 cc. It’s an upgrade battery for Yuasa part numbers 51913 and 51814.

“The batteries on BMW motorcycles are especially difficult to access,” said Hitoshi Ohta, chairman and CEO of Yuasa Battery Inc. “This makes it hard for the owner to maintain the battery on a regular basis. The new Yuasa YT19BL-BS battery is a sealed, maintenance-free AGM design, so there is no need to check the fluid level.” 

The Yuasa YT19BL-BS battery is 12 volts, rated at 170 CCA and 17.7 AH, The battery measures 7.44" x 3.19" x 6.69" (185mm x 81mm x 170mm) and weighs 12.5 lbs. (5.7 kg).

The AGM technology used in the YT19BL-BS is an advanced battery design that eliminates water loss. Because of its lead calcium design, an AGM battery will hold its specific gravity more than three times longer than conventional lead antimony types. This means much longer periods between charges when the battery is used less frequently, such as winter storage.

The Yuasa YT19BL-BS AGM battery is shipped dry along with its own pack of electrolyte that is added at the time of installation. Once filled with electrolyte from its special packs, an AGM battery is virtually maintenance free. The electrolyte is absorbed in the special plates and separators, so there is no need to worry about leaks on the valuable vehicle parts and accessories.

Prices vary a bit depending on where you buy, but expect to pay between $100 and $115 for a YT19BL-BS. For more information about this battery and the full line of Yuasa performance products and premium accessories, visit
