Yuasa YUAM720GH Motorcycle Battery Review Powerful AGM Performance Tested

Description

Ice Quality & Type

Testing the Yuasa YUAM720GH GYZ20HL Factory Activated GYZ H Series AGM Battery has been quite an experience, especially considering its reputation for power and reliability. This AGM battery uses Absorbed Glass Mat technology, which means it’s nonspillable and designed to resist vibration—key features for motorcycle batteries that have to endure rough rides. The battery’s design keeps the electrolyte absorbed in the glass mats, preventing leaks and reducing maintenance. I noticed that the power output is consistently strong, which directly translates to reliable starts and steady performance even in colder climates. The quality feels solid, and the sealed valve-regulated design means I never had to worry about refilling water or electrolyte, a relief compared to older flooded batteries I’ve dealt with.

Noise Levels

A motorcycle battery doesn’t usually contribute to noise, but I did pay attention to any humming or unusual sounds while the battery was in use. The Yuasa YUAM720GH GYZ20HL was completely silent, which is expected for this type of product. It’s reassuring knowing the battery isn’t generating any distracting electrical noise, especially when I’m on a long ride or in a quiet neighborhood. The absence of noise aligns with the quality build and the premium materials Yuasa uses in their AGM batteries.

Features

This model stands out with some impressive specs. Featuring a Cold Cranking Amps (CCA) rating of 320 at 0°F, it provides excellent starting power. The extra surface area on the taller plates increases power output, which I appreciated when powering additional motorcycle accessories like heated grips and auxiliary lights. The 20 Ah capacity ensures that my bike’s electrical system stays well-supported. The factory activation means it comes pre-filled, sealed, and charged, which saved me a ton of hassle—no messy acid handling or initial setup required. The valve-regulated design eliminates water loss and the need for refilling, making it a true maintenance-free experience.

Durability

My experience with the Yuasa AGM battery’s durability has been positive so far. Its enhanced active materials and separator compounds are clearly designed to withstand the constant vibration and shocks from riding. Over several months of daily use, including some off-road adventures, the battery held up well without any noticeable drop in performance or physical damage. I remember one particularly bumpy ride where I was sure my old battery would have suffered, yet this one kept going strong. The robust construction gives me confidence for long-term use, which is crucial given how hard motorcycle batteries get worked.

Ease of Use

Installing the battery was straightforward, thanks in part to the included screw kit and the compact, well-thought-out design. Since it’s factory activated and sealed, there was no need to add acid or wait for charging, which is a huge convenience. My friend, who’s less experienced with bike maintenance, found it easy to swap out his old battery with this one too. The size fits perfectly in standard motorcycle battery compartments, and the nonspillable design means I never had to stress about leaks during installation or handling.

Ice Production Speed

Of course, this battery doesn’t produce ice like an ice maker, but thinking about the speed at which it delivers power to start my bike is key. The Yuasa GYZ H Series AGM Battery kicks the engine to life quickly—a feature I tested especially during cold mornings when other batteries tend to struggle. The high CCA rating really comes through here; the bike fired up almost instantly without hesitation, even in temperatures below freezing. That quick start saves me time and frustration, especially during winter months.

Warranty

Yuasa stands behind their product with a warranty that offers peace of mind, and the Yuasa YUAM720GH GYZ20HL is no exception. The coverage period is reasonable for a motorcycle battery in this price range, and the warranty terms are clearly stated. While I haven’t had to use it, knowing there’s support available if something goes wrong adds value. It’s reassuring to buy from a manufacturer that offers genuine backing for their product’s longevity.

Price Performance

Evaluating the battery’s price performance, I find it to be a solid investment considering the features and durability it offers. It’s not the cheapest battery on the market, but the factory activation, maintenance-free operation, and robust build justify the cost. Compared to budget batteries that often fail under vibration or lose charge quickly, this model delivers better value over time. The reliability and convenience factors make it worth paying a bit more, especially for daily riders or those with accessory-heavy bikes.

Product Competitors

Looking at similar products, the Yuasa YUAM720GH GYZ20HL faces competition from brands like Odyssey and Shorai, which also offer AGM and lithium batteries for motorcycles. Odyssey batteries often boast higher CCA ratings but come with a heavier weight and sometimes a higher price tag. Lithium batteries like Shorai’s are lighter and offer long lifespan but can be more sensitive to charging conditions and generally cost more upfront. The Yuasa strikes a balance with its durability, power output, and maintenance-free design. Its nonspillable AGM technology and factory activation give it an edge over flooded batteries, but it might not be the lightest option on the market. For riders who want reliability and ease without breaking the bank, this product competes well.

Advantages

• High Cold Cranking Amps (320 CCA) ensure quick and reliable starts, even in cold weather
• Maintenance-free factory activation saves time and avoids mess
• Absorbed Glass Mat design prevents spills and extends battery life
• Durable construction withstands vibration and rough conditions

Drawbacks

• Slightly heavier compared to some lithium battery alternatives
• Could be overkill for riders with minimal electrical accessory use
• Premium price point may deter budget-conscious buyers

Using the Yuasa GYZ H Series battery daily has been a relatively hassle-free experience. Its power and reliability impressed me, although its weight and cost might not suit everyone’s needs. Still, for those prioritizing dependability and ease of maintenance in their motorcycle battery, this is a strong contender that delivers on its promises.
