A strong AGM motorcycle battery should match your bike’s required case size and terminal layout while providing enough cranking power for its engine and accessories. The UPLUS YTX30L-BS is a leading choice for riders needing a higher-capacity option, with 30Ah and 400 CCA; smaller motorcycles and scooters may call for a more compact battery instead. This roundup compares ten sealed powersport batteries, from the 6Ah Mighty Max YTX7L-BS to Yuasa’s GYZ20HL, listed with up to 32Ah and 500 CCA.
The products vary in dimensions, stated vehicle compatibility, capacity and cranking figures, so a familiar model name alone is not enough to confirm fit. Check your motorcycle’s manual and old battery before ordering, especially its dimensions and positive-terminal position.
The UPLUS YTX30L-BS leads this roundup for riders who need a high-capacity AGM replacement: its listed specifications give it 12V, 30Ah and 400 CCA, with fitment across motorcycles, ATVs, snowmobiles and UTVs. It is maintenance-free and measures 6.54 x 4.96 x 6.81 inches. That size is not universal, so confirm your bike’s required battery code, dimensions and terminal layout first.
For a smaller case or a different fitment, compare the other ranked options rather than choosing on capacity alone.

- Dimensions: 3.43"D x 5.91"W x 5.12"H
- Voltage: 12 V
- Compatible with Vehicle Type: ATV, street-cruiser-motorcycles…
Best for: Longer-storage motorcycle battery.
Why it ranks #8: The sealed 12V AGM battery lists 195 CCA and fits specified ATVs, scooters and several motorcycle categories, including street-cruisers and touring motorcycles.
The ExpertPower YTX12-BS is specified to retain voltage for longer periods, supporting less frequent charging during storage or standby.

9. Goodyear GYTX14L
- Dimensions: 5.9"D x 3.3"W x 5.7"H
- Voltage: 12 V
- Compatible with Vehicle Type: ATV
Best for: Flexible-mounting all-weather use.
Why it ranks #9: It offers 16Ah and 210 CCA with sealed, maintenance-free construction, but its listed vehicle compatibility specifies ATV rather than motorcycle.
The Goodyear GYTX14L can be mounted in any position except upside down, giving buyers more installation flexibility than a fixed-orientation battery. Its sealed, maintenance-free 12V design supplies 16Ah and 210 CCA, with listed resistance to shocks, vibration, and extreme temperatures for varied powersports operating conditions.
Flexible mounting can help where the battery compartment requires a non-upright position, although the listing excludes upside-down installation. The 5.9 x 3.3 x 5.7-inch dimensions provide a reference for checking that space, and the 210 CCA and 16Ah ratings define its electrical output. Sealed construction removes water-refill and acid-level checks. Goodyear also lists shock, vibration, and extreme-temperature resistance, plus deep-discharge recovery, features relevant to powersports use and storage.
- Mountable in any position except upside down
- Sealed and maintenance-free
- 16Ah capacity and 210 CCA
- Shock, vibration, and extreme-temperature resistance listed
- The 210 CCA rating is below the 310 CCA listed for the Daakmax YTX20L-BS.
Skip it if you need 310 CCA in a YTX20L-BS size; the Daakmax YTX20L-BS lists that output and an 18Ah capacity.
This is a useful match for buyers who need flexible mounting and a sealed battery for a compatible ATV or other listed application. Its 210 CCA and prohibition on upside-down mounting are important boundaries.

10. Mighty Max YTX7L-BS
- Dimensions: 4.4"D x 2.75"W x 5.19"H
- Voltage: 12 V
- Compatible with Vehicle Type: Scooter
Best for: Small scooter battery replacement.
Why it ranks #10: This 12V AGM battery provides 6Ah and 100 CCA, and its listed compatible vehicle type is scooter, making its stated fit less suited to motorcycle shoppers.
The Mighty Max YTX7L-BS pairs a compact 4.40 x 2.75 x 5.19-inch body with a 12V, 6Ah rating and 100 CCA, making it a clearly specified option for a matching small-battery application. Its sealed SLA/AGM construction is rechargeable and maintenance-free, with spill-proof operation and deep-discharge recovery listed.
The compact dimensions and stated positive-right, negative-left polarity help buyers compare the unit with a scooter’s existing battery before installation. Its 100 CCA and 6Ah capacity define a modest output profile, while the 12V sealed lead-acid AGM design supports rechargeable use without a stated need for regular maintenance. The listing also identifies a high discharge rate, wide operating temperatures, long service life, and deep-discharge recovery, giving owners practical operating characteristics to weigh.
- Compact 4.40 x 2.75 x 5.19-inch dimensions
- 12V, 6Ah, and 100 CCA specifications
- Spill-proof SLA/AGM design
- Deep-discharge recovery is listed
- The listing includes battery and screws only, not a wire harness or mounting accessories.
Skip it if you need 18Ah and 310 CCA; the UPLUS EB20H-3 lists those ratings for its YTX20HL-BS replacement size.
This suits scooter owners needing a 12V replacement with the listed YTX7L-BS dimensions and polarity. The 6Ah, 100 CCA rating is the key boundary, and installation may require separate harness or mounting accessories.

View on AmazonAvoiding fitment and terminal-layout mistakes
A battery with a familiar replacement code can still be the wrong physical fit if its dimensions or terminal positions differ from the original. These listings show why checking all three matters: the UPLUS YTX30L-BS measures 6.54 x 4.96 x 6.81 inches, while the YTX20-sized options measure 6.89 x 3.43 x 6.1 inches. The UPLUS YTX30L-BS lists a [- +] terminal arrangement; the Weize YTX20L-BS specifies negative on the left and positive on the right.
Before ordering, compare your manual’s required battery code, the old battery’s case dimensions, and the cable positions. Do not assume that a battery with similar capacity or a shared replacement-code family will fit your tray or let the cables reach safely.
Also confirm the product’s stated vehicle compatibility; some listings specify a broad set of powersports vehicles, while others name only a narrower vehicle type.
What sealed AGM does—and does not—mean for upkeep
Sealed AGM construction removes routine water topping-off, but it does not make a battery immune to discharge or poor storage. Several listings describe maintenance-free, spill-resistant designs: the Energizer TX20HL is factory-sealed and arrives fully charged, while the ExpertPower YTX12-BS is described as sealed with a low self-discharge rate. Those features can reduce handling and routine checks, but they do not establish how long a battery will last in a particular motorcycle or how it will perform after being left unused.
A discharged battery may still need appropriate charging, and the product data does not specify a universal charging procedure. Follow the motorcycle and battery manufacturers’ instructions, use a charger suitable for the battery type, and check charge before a long period of storage.
For riders who want less acid handling, the sealed options offer convenience; they still need correct charging and fitment.
How to Choose an AGM Motorcycle Battery
Case dimensions and terminal position
Start by matching the required battery code, physical dimensions and terminal layout to your motorcycle. Listed cases span the compact Mighty Max YTX7L-BS at 4.40 x 2.75 x 5.19 inches, the 5.91 x 3.43 x 5.12-inch ExpertPower YTX12-BS and the 6.89 x 3.43 x 6.1-inch YTX20 options. The UPLUS YTX30L-BS is wider at 4.96 inches and measures 6.54 x 6.81 inches across its other listed dimensions.
Terminal notation also varies: some listings show [- +], while Weize specifies negative-left and positive-right. A small case may suit a compact tray; larger cases suit only bikes designed for those dimensions.
Verify polarity against the old battery and manual.
Cold-cranking amps
Choose a stated CCA figure that meets your motorcycle maker’s requirement, rather than assuming the largest number is always the right fit. Among products with a listed figure, this set ranges from 100 CCA for the Mighty Max YTX7L-BS to 400 CCA for the UPLUS YTX30L-BS; Yuasa describes the GYZ series as reaching up to 500 CCA. The YTX20 choices list 300 or 310 CCA, and the Goodyear GYTX14L lists 210 CCA.
Yuasa YTZ14S does not provide a specific CCA value in the supplied specifications. A higher output may suit a larger engine or accessory demands when the battery is compatible, while a smaller motorcycle should use the specification required for its exact model.
Capacity and vehicle fit
Compare amp-hour capacity and the manufacturer’s vehicle-compatibility listing alongside the battery code. Listed capacities range from 6Ah for the Mighty Max YTX7L-BS and 11.8Ah for Yuasa YTZ14S to 18Ah for several YTX20 options and 30Ah for UPLUS YTX30L-BS; Yuasa’s GYZ series is described as reaching 32Ah. The listings name motorcycles across several products, but some are narrower: Goodyear specifies ATV, and Mighty Max specifies scooter.
A higher capacity can be useful where the bike’s specified battery size and electrical needs call for it, but capacity alone cannot confirm fit. Riders should favor a listing that names their vehicle type and matches the manual’s required code, dimensions and electrical specifications.
Which AGM Motorcycle Battery Should You Choose?
For a motorcycle that takes a large YTX30L-BS case and needs strong listed output, choose UPLUS YTX30L-BS: it offers 30Ah and 400 CCA. If your vehicle calls for a YTX20-size battery, UPLUS YTX20HL-BS lists 310 CCA and broad powersports compatibility; Energizer TX20HL also gives 310 CCA and arrives fully charged. For a high-output option, consider Yuasa GYZ20HL, whose series is listed with up to 500 CCA and 32Ah, but verify the fit carefully because its stated compatible vehicle type is personal watercraft.
Motorcycle owners seeking a specifically motorcycle-listed Yuasa option can check Yuasa YTZ14S. For compact requirements, compare ExpertPower YTX12-BS or Mighty Max YTX7L-BS only if their dimensions and lower stated outputs match your bike.
Always confirm the exact battery code, size and polarity first.

Frequently Asked Questions
How can I confirm an AGM battery will fit my motorcycle before ordering?
Compare the battery code, dimensions, terminal layout, and polarity with your motorcycle’s manual or the battery currently installed. A shared voltage or broad vehicle-type listing does not guarantee fit. Confirm the exact requirements with your motorcycle maker or the seller before ordering.
Should I charge a factory-activated or fully charged AGM battery before installation?
Follow the battery maker’s instructions and check its charge before installation. A factory-activated label or a listing that says fully charged does not mean every battery needs the same preparation. If charging is needed, use a charger approved for AGM batteries and follow its instructions.
How should I maintain and store an AGM motorcycle battery between rides?
Follow the battery maker’s storage and charging guidance, keep the battery clean and secure, and check its charge periodically during long periods without riding. If it needs charging, use a compatible AGM charger. Before storage or reconnection, consult your motorcycle manual for safe handling instructions.
What do CCA and amp-hours tell me when comparing batteries?
CCA indicates a battery’s listed cold-cranking output, while amp-hours describe its rated capacity. These figures help compare listed performance, but they do not establish whether a battery fits your motorcycle. Check the required battery code, dimensions, and terminal arrangement as well as the output figures.
Can a battery listed for ATVs or other powersports vehicles fit a motorcycle?
It can, but a broad powersports compatibility listing is not enough to confirm motorcycle fit. Match the battery’s code, dimensions, terminal layout, polarity, and electrical requirements to your motorcycle’s manual or existing battery. Verify the specific application before ordering, especially when the listing emphasizes another vehicle type.
Final Words
Start with your motorcycle’s required battery code, dimensions, and terminal layout, then compare the matching options rather than selecting by output alone. For a bike that takes the larger YTX30L-BS case, UPLUS leads with listed 30Ah and 400 CCA. If your bike needs a different size, consider the corresponding ranked alternative and verify fitment carefully—particularly for options listed mainly for other vehicle types.
