A strong side-by-side battery should match your machine’s required group size, terminal layout, and starting demand; the AJC replacement is the clearest fit for specified Yamaha Rhino models. This roundup compares ten options, from a Rhino-specific AGM battery to UTV-compatible batteries with stated outputs of 400 to 500 CCA, plus compact powersport replacements. Several listings cover ATVs or UTVs broadly, but broad compatibility wording is not proof that a battery fits a particular side-by-side.
Check the existing battery and your vehicle’s manual before ordering, especially for dimensions, polarity, and terminal type. The products also differ in chemistry and capacity, so compare those figures only after confirming physical fit.
Our rankings put explicit side-by-side fit first, then prioritize listed compatibility and useful starting specifications.
The AJC Rhino 450-660 Replacement leads because its listing specifically identifies the Yamaha Rhino 450–660 4WD side-by-side and model years 2006–2008, and gives 300 CCA, 12 volts, and AGM construction. It is the most directly matched option here for those Rhino models. For other UTVs, compare the required battery size, terminals, polarity, and starting needs against the manual; the TYKOOL YTX14-BS Lithium, UPLUS YTX30L-BS, and Yuasa GYZ16H offer different stated CCA and fitment details.

8. Upstart YTX14-BS
- Dimensions: 6"D x 3.48"W x 5.8"H
- Voltage: 12 V
- Compatible with Vehicle Type: ATV, Cruiser/ Touring, Dirt Bike, Street…
- Weight: 4.26 kg
Best for: Ready-to-install replacement.
Why it ranks #8: Its listing includes UTV compatibility and a factory-activated, maintenance-free 12-volt sealed lead-acid design, but does not provide a CCA figure.

9. Goodyear GYTX14AH
- Dimensions: 5.2"D x 3.4"W x 6.4"H
- Voltage: 12 V
- Compatible with Vehicle Type: ATV
Best for: Flexible-mount AGM for powersports.
Why it ranks #9: The listing names UTV compatibility and specifies 12 volts, 14 Ah, and 210 CCA, though its stated dimensions differ from several YTX14 listings.

The flexible-mount claim can help with installation in a compartment where orientation is constrained, though Goodyear explicitly excludes upside-down mounting. Its sealed, maintenance-free construction means no water refills or acid-level checks, while the 14Ah capacity and 210 CCA offer figures to compare against the original battery. Goodyear also describes resistance to shocks, vibration, and extreme temperatures; its 5.2 by 3.4 by 6.4-inch dimensions support a physical-fit check.
- 12V, 14Ah capacity
- 210 CCA
- Mountable in any position except upside down
- Sealed, maintenance-free construction
- The stated 210 CCA is lower than the 220 CCA ExpertPower YTX14-BS.

- Dimensions: 5.2"D x 3.5"W x 6.4"H
- Voltage: 12 V
- Compatible with Vehicle Type: Scooter
Best for: Compact 210 CCA AGM.
Why it ranks #10: This 12-volt, 12-Ah battery lists 210 CCA and dimensions of 5.2 by 3.5 by 6.4 inches, but its stated vehicle fit is scooter.
The Mighty Max YTX14AH specifies 210 CCA in a 5.2-by-3.5-by-6.4-inch case, giving buyers both a cranking figure and dimensions for a replacement check. Its sealed, rechargeable AGM construction is maintenance-free and is listed for scooter use.
The 210 CCA and 12Ah ratings help buyers compare this battery with the requirements of a compatible machine, while the stated dimensions offer a practical space check before installation. Mighty Max describes the AGM unit as spill-proof, rechargeable, and suitable for mounting in different orientations. The listing specifies positive-left, negative-right polarity and includes battery screws, but no wire harness or mounting accessories, so owners should plan for those connection and mounting needs.
- 12V, 12Ah capacity
- 210 CCA
- Spill-proof, maintenance-free AGM construction
- Polarity and battery screws specified
- Wire harness and mounting accessories are not included.
Skip it if you require a supplied wire harness or mounting accessories; this listing includes the battery and screws only.

A familiar battery code does not guarantee a side-by-side battery will fit: verify the tray, terminal position, and cable reach. The listings show why. Several YTX14-BS options give dimensions near 5.9 by 3.4 by 5.7 inches, while the Goodyear GYTX14AH and Mighty Max YTX14AH are listed at about 5.2 by 3.5 by 6.4 inches.
Similar names do not establish identical case dimensions or terminal layouts. The AJC Rhino Replacement is a different fit proposition: it names specific Rhino 450–660 4WD models and Group-U1 replacements, while listing polarity 0 and NB terminals.
Before purchase, compare the existing battery label and measure the compartment; then verify terminal orientation and connector type in the vehicle documentation. Treat broad ATV or UTV compatibility as a starting point for checking, not confirmation of exact fit.
AGM or lithium: check the charging system
A lithium battery is not automatically a drop-in substitute for an AGM battery, because the listings do not establish that every side-by-side charging system supports both chemistries. This selection includes sealed AGM or lead-acid options such as the ExpertPower YTX20L-BS and UPLUS YTX30L-BS, alongside LiFePO4 choices from TYKOOL and KEMIMOTO. Their listed figures are not directly comparable as capacity alone: TYKOOL states 8 Ah and 480 CCA, while KEMIMOTO states 12 Ah and cautions buyers to match amp rating with the original.
Check the vehicle maker’s battery and charging-system guidance before changing chemistry, and confirm the replacement’s required charging method. If that guidance is unclear, a same-chemistry replacement with matching dimensions, polarity, and terminal arrangement avoids assuming an unverified compatibility.
How to Choose a Side-by-Side Battery
Exact fit and terminal layout
Start by matching the battery to the vehicle and tray, rather than relying on a similar model code. The AJC Rhino Replacement explicitly targets Yamaha Rhino 450–660 4WD models from 2006–2008 and identifies Group-U1 replacements, polarity 0, and NB terminals. Many YTX14 listings instead give dimensions around 5.9 by 3.4 by 5.7 inches, while the Goodyear and Mighty Max YTX14AH listings are about 5.2 by 3.5 by 6.4 inches.
Compare your original battery’s dimensions, terminal position, and connector type with the listing and manual. Rhino owners within the listed fitment should start with AJC; buyers of other models need model-specific confirmation before choosing a broadly compatible option.
Starting power and capacity
Choose a battery whose starting and capacity requirements meet the vehicle maker’s specifications; the largest number in a listing is not automatically the right fit. Listed CCA spans 210 on the Goodyear GYTX14AH and Mighty Max YTX14AH, 275 on the ExpertPower YTX20L-BS, 300 on the AJC Rhino Replacement, 400 on the UPLUS YTX30L-BS, 480 on the TYKOOL YTX14-BS Lithium, and up to 500 on the Yuasa GYZ16H. Capacity figures range from 8 Ah for TYKOOL to 30 Ah for UPLUS among products that state Ah.
A machine with higher specified starting demands may favour the stronger listed CCA options, while replacement buyers should match their original specification rather than simply maximizing output.
Battery chemistry and maintenance
Check whether your machine calls for AGM or supports LiFePO4 before selecting a chemistry. The ExpertPower, Goodyear, and Mighty Max listings describe sealed AGM or SLA batteries, while TYKOOL and KEMIMOTO are identified as lithium or LiFePO4. Several AGM listings describe maintenance-free construction; ExpertPower says its sealed design requires no maintenance, and Goodyear says it needs no water refills or acid checks.
TYKOOL lists a 12.8-volt lithium battery and included terminal hardware; KEMIMOTO advises matching amp rating to the original battery. Riders replacing an existing AGM battery may prefer a like-for-like chemistry when compatibility is uncertain.
Those considering lithium should first confirm the vehicle’s charging-system requirements and whether the listed case and terminals suit their machine.
Which Side-By-Side Battery Should You Choose?
For a Yamaha Rhino 450–660 4WD from 2006–2008, choose the AJC Rhino Replacement first: it is the only listing here that names that side-by-side fit directly. For a different UTV that needs a YTX14-BS-sized lithium battery, consider the TYKOOL YTX14-BS Lithium, which lists 480 CCA, after verifying chemistry and fit. If the original calls for a larger YTX30L-BS, the UPLUS YTX30L-BS offers 30 Ah and 400 CCA.
The Yuasa GYZ16H is another UTV-listed option, with up to 500 CCA and 32 Ah. For a YTX20L-BS AGM replacement, the ExpertPower YTX20L-BS lists 20 Ah and 275 CCA.
In every case, confirm dimensions, polarity, terminals, and vehicle-specific requirements before ordering.

Frequently Asked Questions
How can I confirm a replacement battery fits my side-by-side before ordering?
Check the vehicle manual or existing battery for the required battery size, chemistry, voltage, terminal layout, polarity, and starting needs. Compare those details with the listing, including any stated vehicle fitment. Confirm the battery’s dimensions and terminal positions; a similar model name alone does not establish that it will fit.
Can I replace an AGM side-by-side battery with a lithium battery?
Yes, but only if the vehicle supports that chemistry and the replacement matches its fit and starting requirements. Check the manual for battery type and charging-system compatibility, then compare dimensions, terminals, polarity, and stated cranking performance. Do not assume a lithium battery is interchangeable with an AGM battery just because the model designation is similar.
What should I check if a new side-by-side battery will not crank the engine?
First verify that the battery is charged and that its terminals are correctly positioned, firmly connected, and free of poor contact. Confirm polarity and fit against the manual, then check the vehicle’s battery connections and starting system. If these checks do not resolve the issue, consult the vehicle or battery instructions before further troubleshooting.
How much cranking performance should I look for?
Use the vehicle manual or the original battery’s stated requirement as your reference, then compare it with the replacement listing’s CCA. The products here list different CCA figures, so do not select by battery type or size alone. Confirm that the candidate meets the vehicle’s stated starting needs and fits correctly.
What should I consider when choosing between battery capacities?
Match the battery type and capacity to the vehicle’s requirements rather than assuming a higher listed capacity will fit or work. Check the manual and original battery, then verify dimensions, terminals, polarity, and chemistry. The listings include different capacities, so treat their figures as comparison details, not a substitute for vehicle-specific fitment.
Final Words
For a Yamaha Rhino 450–660 4WD from 2006–2008, the AJC replacement is the clearest choice because its listing names that fitment and states 300 CCA, 12 volts, and AGM construction. For other UTVs, start with the manual and compare size, terminals, polarity, chemistry, and required cranking performance. Then consider the listed alternatives only when their fit and battery type match your vehicle.
