10 Best Harley Davidson Motorcycle Batteries 2026 in the United States

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.

This battery replaces several popular models, offering good compatibility with a range of motorcycles and powersports vehicles. The main drawback is the CCA rating of 300, which is decent but might be on the lower side for very demanding cold starts in extreme weather. Also, the recommended replacement every two years means it’s not the longest-lasting battery, but this is fairly typical for sealed AGM types. Customers appreciate the solid value, easy installation, and reliable performance, backed up by a one-year warranty and responsive customer support. If you want a maintenance-free, reliable battery that fits many Harley-Davidson motorcycles without breaking the bank, this is a practical choice to consider.

The Weize Lithium YTX30L-BS is a 12V 10Ah lithium iron phosphate (LiFePO4) battery designed as a replacement for motorcycle batteries, including Harley-Davidson models that match its size and terminal layout. 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.

The built-in smart Battery Management System (BMS) protects against overcharging, excessive discharge, short circuits, and extreme temperatures, enhancing safety and performance. Another big plus is that it requires no maintenance—no water refills or acid handling—and comes fully charged and ready to install. Its compact dimensions (approximately 6.5 by 5 by 7 inches) and terminal placement (left negative, right positive) mean you need to compare carefully with your existing battery to ensure a proper fit.

This battery is an excellent option for riders looking for a lightweight, long-lasting, and safe battery replacement. People with motorcycles requiring a different size or terminal arrangement will need to look elsewhere. While lithium batteries may be more expensive upfront than traditional batteries, their extended life and low upkeep can offset the initial cost. This makes the Weize Lithium YTX30L-BS a hassle-free, powerful, and modern eco-friendly battery solution that suits compatible bikes.

The UPLUS YTX30L-BS is a sealed lead-acid (AGM) battery designed for motorcycles, including Harley-Davidson models that require a 12V, 30Ah battery with around 400 cold cranking amps (CCA). Its AGM design means it’s maintenance-free—no need to check water levels or worry about leaks—making it convenient and reliable for riders who want a hassle-free experience. The battery is factory activated and ready to use right out of the box, which is great if you want a quick replacement. Measuring about 6.5 by 5 by 7 inches, it fits the YTX30L-BS size class, which matches many Harley-Davidson models, so it should fit easily in the battery compartment.

The 400 CCA rating provides decent starting power, sufficient for most Harley motorcycles to start smoothly, even in cooler weather. Another strong point is the high-quality lead used, which improves charging and durability while reducing harmful fumes. Customers have generally rated it well, and UPLUS offers a 15-month warranty with local support in the US, adding peace of mind.

On the downside, while 400 CCA is good for typical Harley use, riders in very cold climates or with larger engines might want a battery with a higher CCA for more reliable starts. Also, at 18 pounds, it is on the heavier side, which is typical for AGM but something to consider if weight is a concern. This battery is a solid choice for Harley-Davidson owners seeking a maintenance-free, reliable battery that fits well and delivers dependable starting power for everyday riding conditions.
