A strong quad battery should match the original voltage, fit the battery tray and deliver enough cranking power for the engine; the OPTIMA QUAD30 suits riders seeking a high-capacity 12.8V lithium option for an ATV or 4-wheeler. This roundup compares ten products, from compact 3Ah AGM replacements to a 15Ah lithium battery and a complete 24V kit for select Dirt Quad models. The products are not interchangeable: dimensions, terminal layout and intended application differ, and some listings describe specific replacement groups.
Check your quad’s manual and existing battery label before choosing. For a conventional ATV replacement, options include AGM batteries rated at 3–12Ah and lithium models listing up to 480 CCA.
The comparison below separates those choices from the dedicated Dirt Quad kit.
The OPTIMA QUAD30 is the leading choice for a quad when its size and replacement fit match your machine. It is a 12.8V LiFePO4 battery rated at 15Ah, with 800 cranking amps and a built-in engine-start reserve; the listing names ATV, UTV and 4-wheeler use. Its 4.92 x 6.54 x 6.71-inch dimensions make fit verification essential.
For a compatible Dirt Quad instead of a gasoline ATV, the Vici 24V 7Ah kit is the more directly tailored option, but it excludes Dirt Quad 500 series models.

#4 · Highest AGM Capacity
4. Mighty Max YTX14-BS
- Voltage: 12 V
- Dimensions: 6"D x 3.44"W x 5.75"H
- Compatible with Vehicle Type: ATV
Best for: Higher-capacity AGM ATV replacement.
Why it ranks #4: The ATV-compatible AGM provides 12Ah and 200 CCA at 12V, making it a substantial conventional replacement when the tray and polarity match.
With 12Ah capacity and 200 CCA, the Mighty Max YTX14-BS offers substantially more listed capacity and cranking output than compact 3Ah batteries. Its sealed, rechargeable AGM format suits ATV owners seeking a maintenance-free replacement in the specified 6.00-by-3.44-by-5.75-inch size.
The 12-volt battery's 200 CCA rating supports starting needs beyond those of small-format batteries, while its 12Ah capacity provides a larger reserve than a 3Ah unit. AGM construction is spill-proof and sealed, and the listing describes deep-discharge recovery and wide operating-temperature capability. It arrives charged and ready to install, but the package contains the battery and screws rather than a wire harness or mounting accessories. Check the positive-left, negative-right layout and case dimensions before installation.
- 12V, 12Ah capacity
- 200 CCA rating
- Sealed, spill-proof AGM design
- Charged and ready to install
- Its 6-inch case and 10-pound weight may not suit compact battery compartments.
Skip it if you need a small YTX4L-BS-format battery; the ExpertPower YTX4L-BS has a much smaller listed case.
This Mighty Max fits ATV owners who need a 12Ah, 200-CCA AGM replacement and have room for its listed case. Confirm the compartment dimensions and positive-left polarity, since the larger format will not suit every quad.

A power display and pure copper terminals support charge-status checking and high-current discharge, while the threaded posts simplify terminal fastening. Five EVA spacers help adjust the fit in the tray, and the battery is described as pre-charged. The product information says a LiFePO4 charger is required for charging; use a suitable 14.6V charger for a full charge rather than assuming a conventional charger is appropriate.
- 480A CCA rating
- 6Ah lithium battery
- Five universal-fit EVA spacers included
- Power display and threaded-lug posts
- A LiFePO4 charger is required; the listing recommends 14.6V for a full charge.
Skip it if you want a battery that arrives with a wiring harness; the Vici 24V Dirt Quad kit includes one.
This KEMIMOTO fits quad owners seeking high cranking output, adjustable spacing, and a charge-status display. Factor in the stated lithium-charger requirement and verify the 5.91-by-3.43-by-3.66-inch case and terminal arrangement for the vehicle.

7. Daakmax YTX5L-BS
- Voltage: 12 V
- Dimensions: 2.8"D x 4.49"W x 4.17"H
- Compatible with Vehicle Type: ATV, Motorcycle, Personal Watercraft…
Best for: Compact 80-CCA AGM replacement.
Why it ranks #7: This 12V AGM replacement lists ATV and UTV compatibility, 4Ah capacity and 80 CCA; verify its 4.49 x 2.80 x 4.17-inch size.
The Daakmax YTX5L-BS pairs a compact 4.49-by-2.80-by-4.17-inch case with an 80-CCA rating, giving quad and ATV owners a specified small-format AGM replacement. Its 12V, 4Ah capacity and standard negative-positive terminal layout support straightforward comparison with an existing battery.
The 4Ah capacity and 80 CCA rating make this a higher-output option than a 50-CCA compact battery, while its dimensions help buyers judge whether it fits the available tray. AGM construction is maintenance-free and does not spill acid, with the supplied facts also noting a slower discharge rate than conventional batteries. The standard [- +] terminal layout can simplify matching the old connection orientation. Compare size and terminal position before installation, as the case still must fit the vehicle.
- 12V, 4Ah capacity
- 80 CCA starting rating
- Sealed AGM design that does not spill acid
- Dimensions and terminal layout are specified
- The 80 CCA rating is modest compared with high-output lithium options.
Skip it if you need 480 CCA for a high-compression engine; the TYKOOL LFP14-BS-PRO lists that cranking rating.
This Daakmax suits quad and ATV owners seeking a compact 4Ah AGM battery with 80 CCA. The fit depends on matching its YTX5L-BS dimensions and negative-positive terminal layout to the vehicle's existing battery compartment.

8. ExpertPower YTX4L-BS
- Voltage: 12 V
- Dimensions: 2.76"D x 4.45"W x 3.39"H
- Compatible with Vehicle Type: ATV, street-cruiser-motorcycles…
Best for: Higher-output compact AGM starter.
Why it ranks #8: The 12V AGM lists ATV compatibility, 4Ah and 120 CCA, but its compact YTX4L-BS format may not suit larger quad battery trays.
A 120-CCA rating sets the ExpertPower YTX4L-BS apart among compact 4Ah AGM replacements, providing more listed cranking output than a standard 50-CCA unit. Its 12V format and YTX4L-BS replacement claim cover ATVs, scooters, motorcycles, and dirt bikes.
The 4Ah capacity is an upgrade over standard 3Ah units according to the supplied listing, while 120 CCA supports starting across varied temperatures, including cold-start conditions. Its 4.45-by-2.76-by-3.39-inch dimensions make tray comparison practical, and the stated direct replacement fit covers YT4L, GTX4L, and GT4L models. Sealed lead-acid AGM construction provides a rechargeable replacement format. Check the vehicle's required terminal orientation and dimensions, since the supplied specifications do not state polarity.
- 12V, 4Ah capacity
- 120 CCA starting rating
- Direct replacement claim for YT4L, GTX4L, and GT4L
- Compact 4.45 x 2.76 x 3.39-inch dimensions
- Terminal polarity is not specified in the supplied product details.

9. UPLUS YTX4L-BS
- Voltage: 12 V
- Dimensions: 2.76"D x 4.45"W x 3.35"H
- Compatible with Vehicle Type: ATV, Motorcycle, Scooter, Snowmobile, UTV
Best for: Maintenance-free small-format AGM.
Why it ranks #9: It lists ATV compatibility and a maintenance-free 12V AGM design, but its 3Ah and 50A CCA are modest for larger engines.
The UPLUS EB4-3 combines a 12V, 3Ah rating with maintenance-free sealed construction, giving small ATV and powersports batteries a compact AGM replacement option. Its 4.45-by-2.76-by-3.35-inch dimensions and negative-positive terminal layout help buyers assess fit and connection orientation.
This YTX4L-BS replacement uses sealed lead-acid AGM construction, with the listing specifying no spills, leaks, or water checks; that reduces routine battery-care tasks. Its 3Ah capacity and 50A CCA rating place it in the modest-output compact category, so matching the original requirement matters. The stated fit includes ATV, motorcycle, scooter, snowmobile, and UTV applications. Compare the case dimensions and [- +] terminal layout with the existing battery before installing it.
- 12V, 3Ah rating
- 50A CCA listed
- Maintenance-free with no water checks
- Compatible listing includes ATV and UTV
- Its 3Ah capacity and 50A CCA rating limit it to modest starting demands.
Skip it if you need more than 50 CCA from a compact battery; the ExpertPower YTX4L-BS lists 120 CCA.
This UPLUS battery suits quad owners replacing a small YTX4L-BS-format unit who value a sealed, low-maintenance AGM design. Its 3Ah and 50A CCA ratings make it a fit only when those outputs meet the vehicle's requirements.

10. Mighty Max YTX4L-BS
- Voltage: 12 V
- Dimensions: 4.4"D x 2.75"W x 3.42"H
- Compatible with Vehicle Type: Scooter
Best for: Compact scooter and quad replacement.
Why it ranks #10: This 12V AGM lists 3Ah and 50 CCA, and its stated compatible vehicle type is scooter rather than ATV or quad.
A compact 12-volt AGM case measuring 4.40 by 2.90 by 3.42 inches makes the Mighty Max YTX4L-BS a fit to consider when the existing battery uses this small format. Its sealed, rechargeable construction provides a maintenance-free option for compatible powersports applications.
The 3Ah capacity and 50 CCA rating identify this as a modest starting battery rather than a high-output upgrade. Its SLA/AGM construction is spill-proof and rechargeable, and the listing describes broad operating-temperature capability and deep-discharge recovery. The battery arrives charged and sealed, which simplifies initial setup; however, the package includes only the battery and screws, so the installation depends on the vehicle's existing wiring and mounting hardware. Check the stated dimensions and left-negative, right-positive polarity against the original.
- 12V, 3Ah sealed AGM construction
- 50 CCA starting rating
- Compact 4.40 x 2.90 x 3.42-inch listed dimensions
- Arrives charged and maintenance-free
- Only 50 CCA and 3Ah, limiting its fit for higher-demand starting needs.
Skip it if you need a higher-capacity ATV starter; the 12Ah Mighty Max YTX14-BS offers more capacity and 200 CCA.
For a small-format powersports replacement, this Mighty Max suits buyers whose existing battery matches its dimensions and polarity. Its 3Ah and 50 CCA ratings set a clear boundary: verify the vehicle's required output before choosing it for a quad.

View on AmazonAvoid the replacement-group and terminal trap
A battery that shares the right voltage can still be the wrong replacement if its case or terminals do not match your quad. These listings span compact YTX4L-BS formats around 4.4 inches long and 3.3–3.4 inches high, a YTX5L-BS at 4.49 x 2.80 x 4.17 inches, and Group 14-size options around 5.9 x 3.4 x 5.7 inches. The OPTIMA QUAD30 is larger still at 4.92 x 6.54 x 6.71 inches.
Terminal polarity also varies: Mighty Max YTX4L-BS lists negative-left, positive-right, while the YTX14-BS listing specifies positive-left, negative-right. A mismatch can prevent installation or create an electrical hazard.
Before ordering, compare the old battery’s label, case measurements, terminal positions and cable reach with the replacement details; do not assume that a shared YTX label guarantees the same fit.
Lithium power brings a charging trade-off
Lithium models can offer high listed cranking output in a lighter package, but their charging requirements and features differ from AGM replacements. The KEMIMOTO listing explicitly says a lithium battery charger is required and recommends a 14.6V LiFePO4 charger for a full charge; it warns that a 12.8V charger may not fully charge the battery. Its 6Ah and 480 CCA figures therefore do not make it a simple drop-in choice for every quad.
The OPTIMA QUAD30 adds a built-in engine-start reserve and a microprocessor-controlled battery management system, while the AMPXELL YTX4L-BS describes a reboot button and reserve power. Those functions address different battery-management situations, not physical fit.
Confirm the vehicle manufacturer’s charging-system compatibility and the battery maker’s charging instructions before switching chemistry. If compatibility is uncertain, a correctly sized AGM replacement is the more straightforward category to investigate.
How to Choose a Quad Battery
Vehicle fit and terminal layout
Start by matching the battery group, case dimensions and terminal orientation to your quad’s original battery. The products range from compact YTX4L-BS models around 4.4 x 2.8 x 3.3 inches to Group 14-size batteries around 5.9 x 3.4 x 5.7 inches; the OPTIMA QUAD30 measures 4.92 x 6.54 x 6.71 inches. Layouts are not uniform: the Mighty Max YTX4L-BS has negative-left, positive-right polarity, while the YTX14-BS lists the reverse.
Choose a compact replacement only when the original group and mounting space agree. Riders with a larger tray may consider the bigger formats, but should compare the old battery’s dimensions and cable reach first.
For Dirt Quad owners, confirm the exact model series before selecting the Vici kit.
Cranking output and capacity
Choose output based on the quad’s original requirement, not a capacity number alone. Across these options, AGM batteries list 3–12Ah and 50–200 CCA, while the ExpertPower YTX4L-BS lists 4Ah and 120 CCA. Lithium listings include 280-amp cranking current for AMPXELL and 480 CCA for TYKOOL and KEMIMOTO; OPTIMA lists 800 cranking amps and 15Ah.
These figures come from different products and should not be treated as proof of compatibility. A smaller engine using a compact YTX4L-BS replacement may suit a lower-output option if it matches the original specification.
A larger engine or high-compression application may call for more starting output, but only when the battery group, charging system and manufacturer requirements also align.
Battery chemistry and kit contents
Decide whether you need a conventional AGM replacement, a lithium battery, or a complete electric-quad kit. Most listed options are sealed AGM batteries; the lithium products include TYKOOL, AMPXELL, KEMIMOTO and OPTIMA, each with different listed capacities or features. Lithium can reduce listed battery weight—KEMIMOTO lists 2.2 pounds, while Mighty Max YTX14-BS lists 10 pounds—but the KEMIMOTO instructions call for a LiFePO4 charger.
The Vici product is distinct: it supplies two 12V batteries, a wiring harness and an inline fuse for a compatible 24V Dirt Quad. Choose that kit when replacing the specified Dirt Quad system, not as a generic gasoline-ATV battery.
If you only need a direct 12V replacement, favor the chemistry and equipment supported by your vehicle.
Which Battery Should You Choose for Your Quad?
For a gasoline ATV or 4-wheeler that matches its case and charging requirements, choose the OPTIMA QUAD30: it leads with 15Ah, 800 cranking amps and a built-in engine-start reserve. If you own a compatible electric Dirt Quad, select the Vici Dirt Quad Kit for its two batteries, harness and fuse; it does not fit Dirt Quad 500 models. For a 480 CCA lithium option, compare TYKOOL YTX14-BS Lithium with KEMIMOTO Lithium YTX14-BS, noting KEMIMOTO’s charger requirement.
Prefer a conventional ATV-compatible AGM? Mighty Max YTX14-BS lists 12Ah and 200 CCA.
Compact YTX4L-BS products suit only matching trays and requirements. In every case, verify voltage, dimensions, polarity, model fit and charging compatibility against your quad’s manual and existing battery.

Frequently Asked Questions
How do I confirm the correct battery size and terminal orientation for my quad?
Check your quad’s manual and existing battery for the required voltage, dimensions, terminal polarity and orientation, and battery type. Compare those details with the replacement listing before ordering. Physical fit matters: for example, the OPTIMA QUAD30’s listed dimensions make tray and clearance verification essential.
Confirm the battery is compatible with your specific quad model.
Can I replace an AGM quad battery with a lithium battery without changing the charger?
Do not assume the existing charger is compatible. Check the charger’s specifications and the lithium battery’s charging requirements, and confirm both suit your quad before replacing an AGM battery. The KEMIMOTO listing notes a charger requirement, so verify that requirement specifically; the available product information does not establish compatibility with every existing charger.
Why does a quad battery lose charge while the vehicle is parked?
A battery can lose charge from a connected electrical draw, a charging-system issue, or battery condition, even while the quad is parked. Check that accessories are off and inspect the battery and connections. If the loss continues, have the quad’s electrical system and battery checked, and follow the manual’s storage and charging guidance.
What should I check before choosing a compact YTX4L-BS battery?
Confirm that your quad requires the YTX4L-BS size and that the battery’s voltage, terminal orientation, dimensions, and listed capacity and cranking rating meet the manual’s requirements. The roundup includes AGM and lithium YTX4L-BS options, so also check battery chemistry and charging compatibility rather than choosing by size alone.
Which battery is intended for an electric Dirt Quad?
The Vici 24V 7Ah kit is the more directly tailored choice for a compatible Dirt Quad. It includes two batteries, a harness, and a fuse, but it excludes Dirt Quad 500 series models. Confirm your exact Dirt Quad model and the kit’s fit before ordering; it is not the recommendation for a gasoline ATV.
Final Words
Start with the quad’s manual and existing battery: verify voltage, dimensions, polarity, model fit, and charging compatibility. For a gasoline ATV or 4-wheeler, the OPTIMA QUAD30 leads when its case and charging requirements match. For a compatible electric Dirt Quad, consider the Vici kit, excluding 500 series models.
Compare other lithium and AGM options only after confirming their listed requirements suit your machine.
