The Rechargeable YTX20HL-BS High Performance Power Sports Battery by Chrome Battery is a solid option for Harley-Davidson motorcycles. It utilizes Absorbed Glass Mat (AGM) technology, which makes it spill-proof and low-maintenance—ideal for riders who prefer a hassle-free experience.

The Weize YTX20HL-BS motorcycle battery is a sealed AGM type, meaning it’s maintenance-free and won’t leak acid, which is great if you want a hassle-free option. Its capacity of 18Ah and 300 cold cranking amps (CCA) provide solid starting power suitable for many Harley-Davidson models and similar motorcycles. The battery comes fully charged and sealed, so it’s ready to install right out of the box. Another important point is its size: 6.89 x 3.43 x 6.1 inches, which matches many stock battery dimensions, but you should always double-check your old battery’s measurements to ensure the fit and terminal placement are the same. The terminal orientation, with the negative on the left and positive on the right, fits common setups.

It offers 700 cold cranking amps (CCA), providing strong starting power even in cold weather—an important factor for reliable engine starts. Compared to traditional lead-acid batteries, this lithium battery is much lighter at about 7.7 pounds and has a longer lifespan with over 2,000 charge cycles and 50,000+ starts, making it a durable choice.
