Cold mornings at the trailhead are unforgiving. A weak battery turns a four-wheeler into a very expensive piece of yard art, so picking the right cell group, cold-cranking output, and reserve capacity matters far more than most shoppers expect. The AGM (Absorbed Glass Mat, a sealed lead-acid design that resists vibration and spills) units below cover the Group 35, 47, 48, 94R, and 140R fitments most ATVs and side-by-sides ask for, with options that suit everything from weekend trail riding to winch-heavy work.

The Picks, Examined More Closely
If your garage thermometer drops well below freezing in winter, the HQST Group 47 H5 is built around the kind of cold-start performance that matters when you crank an ATV in a frost-covered driveway. Its 680 CCA rating handles the harsh startup loads common to utility quads with winches and light bars, and the absorbed glass-mat construction means you can mount it at a slight angle without worrying about acid leaks.
Riders in northern regions tend to appreciate the wide operating range, which extends down to minus 40 degrees Fahrenheit. Compared to the Interstate option further down, this HQST trades a bit of brand heritage for a noticeably lower entry price, which is a fair trade for weekend warriors who put on fewer miles.
What Pays Off
- 680 CCA delivers confident cold-weather starts down to 0°F
- Sealed AGM design tolerates vibration and angled mounting
- Maintains charge acceptance for vehicles with start-stop systems
- Maintenance-free operation suits occasional weekend use
Worth Noting
- Brand recognition is thinner than ACDelco or Interstate in dealership service bays
- Group 47 dimensions may require tray adjustment on older import models
Quick Facts
Built With In Mind
Riders in regions where winter arrives early and stays late, especially those running winches or plow setups on Group 47 chassis.
Reach For A Different Pick When
The ACDelco Gold 94RAGM suits owners who want a longer warranty window and a stronger dealership support network.
The ACDelco Gold 94RAGM earns its spot through two words: 36-month warranty. That kind of coverage matters when a battery sits exposed to vibration, mud splash, and temperature swings under a seat or in a tight engine bay. For owners who keep vehicles past the five-year mark, the warranty alone justifies the upcharge over generic imports.
Its high cycling capability suits vehicles that spend time idling with accessory loads. For riders running light bars, heated grips, or comms systems on a Group 94R chassis, this is the dependable workhorse option. The trade-off is physical size; the 94R case is longer than the Group 47 H5 alternatives, so measurement matters before clicking buy.
Positive Points
- 36-month warranty provides long-term peace of mind
- High cycling capability handles start-stop driving demands
- Sealed absorbed glass-mat design prevents acid spills
- Strong dealer and parts network simplifies warranty claims
Trade Offs
- Larger footprint than H5 batteries limits vehicle compatibility
- Premium pricing compared to budget AGM alternatives
Feature Snapshot
Whose Shelf It Belongs On
Owners who measure value across years rather than initial outlay, and who prioritize warranty support from a recognized parts brand.
A Better Fit Elsewhere
The Interstate Batteries MTX-47/H5 is the better match for those who prefer Group 47 fitment with a strong AGM pedigree.
European ATV and side-by-side owners chasing the Group 140R LN1 fitment will find the Marxon 140R refreshingly straightforward. At 12V 50Ah with 570 CCA, it targets compact import applications from Audi, BMW, Volkswagen, and Toyota where the battery tray is short on space and long on tolerance for clean dimensions.
Compared to the larger Group 94R options higher on this list, the 140R trades raw cranking amps for a smaller case that actually fits tight European-engine bays. It is a focused pick rather than a flexible one.
Practical Advantages
- Compact Group 140R LN1 footprint suits European imports
- Maintenance-free AGM construction simplifies ownership
- Compatible with start-stop vehicle applications
Minor Gripes
- 570 CCA is lower than full-size truck batteries
- Smaller capacity may struggle with heavy accessory loads
- Limited fitment range beyond specific European models
Who It Suits Best
Import-side owners running compact European chassis where tray dimensions rule out the larger Group 47 and 94R batteries.
Look Elsewhere When
The HQST Group 47 H5 makes more sense for riders on Group 47 chassis who need higher CCA and broader cold-weather headroom.
The Autocessking Group 47 H5 lands in the middle of the pack for a reason. It carries the same 680 CCA and 100 RC ratings as the HQST option, but at a slightly different price band, and owners with both sedan and light-truck applications tend to find the spec sheet checks the right boxes without ceremony.
With a left-negative, right-positive terminal layout, drop-in replacement is realistic for most Group 47 chassis. The trade-off is the same as with most value-tier AGMs: thinner brand heritage and a less robust warranty window.
A Strong Showing
- 680 CCA matches premium-priced competitors
- Standard Group 47 footprint fits sedans and SUVs alike
- Rechargeable AGM chemistry handles repeated start-stop cycles
- 100 reserve capacity for moderate accessory drain
Points To Note
- Terminal orientation must match your vehicle’s existing layout
- Weight at 38.76 lbs is on the heavier side for Group 47
At A Glance
Made For
Sedan and SUV owners seeking straightforward Group 47 replacement without paying premium brand premiums.
Not Your Match When
The ACDelco Gold 94RAGM fits better for full-size truck applications requiring Group 94R dimensions.
Interstate’s MTX AGM line has long been a familiar name in service stations, and the Group 47 H5 version carries that reputation into start-stop vehicles with confidence. The pure-lead AGM construction packs more lead into each cell than conventional AGM designs, and that matters for riders who log long hours with accessories running.
Compared to the Autocessking option above, this Interstate carries 30 fewer CCA but brings stronger construction pedigree. For owners who keep vehicles five years or longer, that longevity often outweighs the small spec difference.
Useful Touches
- Pure lead AGM construction extends cycle life
- Strong brand recognition simplifies warranty service
- Compatible with start-stop vehicle requirements
- 650 CCA handles most climate conditions comfortably
Softer Spots
- 650 CCA trails higher-rated competitors by 30 amps
- Premium price reflects brand positioning
Best Suited To
Owners who measure value in service life rather than initial cost, especially in start-stop trucks and SUVs.
Skip It When
The MARXON Group 94R H7 makes more sense for owners needing 850 CCA and a larger Group 94R fitment.
Relistart’s Group 47 H5 sits in a useful middle ground: 105 minutes of reserve capacity, 680 cold cranking amps, and deep-cycle support for accessories that draw steady current over time. For riders running GPS units, winches, or auxiliary lighting, that extra reserve headroom shows up when the engine is off and the lights stay on.
The terminal layout is standard left-negative, right-positive, and the dimensions (9.53″ L x 6.85″ W x 7.48″ H) align with most Group 47 trays. It is a sensible pick for utility-focused ATV builds where accessory loads matter as much as starting power.
Real-World Strengths
- 105 reserve capacity supports longer accessory runtime
- Deep-cycle capability suits winch and light bar use
- 680 CCA delivers standard cold-weather performance
- Sealed AGM construction handles angled mounting
Honest Caveats
- Less familiar brand than mainstream AGM alternatives
- Verify terminal polarity matches existing battery before install
Who Will Love This
Utility-focused ATV owners running winches, light bars, or comms gear who value reserve capacity over raw cranking amps.
Where A Sibling Pick Shines
The Interstate Batteries MTX-47/H5 suits owners who prioritize brand heritage and service network over reserve capacity.
Subaru Forester owners in the 2019 to 2023 generation tend to land on the MM-G35 because it matches the Group 35 footprint that the factory tray expects. At 12V 55Ah with 650 CCA and 100 minutes of reserve capacity, it covers the daily-driver use case without overspending on capacity the vehicle cannot use.
Compared to the Group 47 entries earlier, this is a smaller and lighter battery by design. The trade-off shows up in deep-cycle recovery; this is a starting battery first and foremost, so winch-heavy builds should look elsewhere.
What Works In Its Favor
- Direct fitment for Subaru Forester 2019 to 2023 models
- Sealed AGM design resists vibration on rough terrain
- 100-minute reserve capacity covers typical accessory drain
- Deep discharge recovery extends usable lifespan
A Few Limitations
- 650 CCA is moderate rather than heavy-duty
- Group 35 size limits fitment to specific chassis
Right Fit For
Subaru Forester drivers from 2019 to 2023 seeking a sealed, maintenance-free Group 35 replacement.
Swap It Out When
The Mighty Max MM-G35 for Nissan Altima (further down) is the better match for sedan applications outside the Subaru range.
The MARXON Group 94R H7 is the heavyweight in this roundup by spec sheet alone. At 12V 80Ah with 850 CCA, it delivers nearly 200 more cold cranking amps than the smaller Group 35 entry above. That margin matters for cold-climate riders and for vehicles running high-compression engines that demand extra cranking muscle.
It also carries a 36-month warranty, matching the ACDelco option earlier. For owners on Group 94R chassis with start-stop systems who want both raw power and warranty protection, this MARXON sits in a useful middle position between the premium-priced ACDelco and smaller Group 47 alternatives.
Benefits That Matter
- 850 CCA delivers top-tier cold-start performance
- 80Ah capacity supports extended accessory use
- 36-month warranty reduces long-term risk
- Faster charging recovery than standard AGM units
Things To Weigh
- Larger 12.4-inch length rules out compact battery trays
- Higher price than Group 47 alternatives
Key Attributes
Perfect Match For
Group 94R chassis owners in cold climates who value high CCA and a multi-year warranty window.
Consider Something Else When
The ACDelco Gold 94RAGM offers similar warranty coverage with stronger brand-name recognition for service shops.
The UPLUS Group 48 H6 sits between the Group 47 entries and the larger Group 94R options, filling a fitment slot common in mid-size SUVs and crossovers. At 12V 70Ah, 760 CCA, and 120 minutes of reserve capacity, it offers a balanced profile for daily-driven vehicles with moderate accessory loads.
Reserve capacity is the standout figure here, edging out the Group 47 alternatives by 15 to 20 minutes. For owners who run small inverters or USB accessory banks while parked, that extra headroom reduces the chance of a no-start the next morning.
A Few Strong Suits
- 120-minute reserve capacity tops this roundup
- 760 CCA balances power and longevity
- Maintenance-free AGM construction simplifies ownership
- Compatible with start-stop vehicle electronics
Practical Considerations
- Group 48 H6 fitment limits to specific mid-size vehicles
- Verify tray dimensions before ordering
Who Should Grab It
Mid-size SUV and crossover owners who value reserve capacity for accessory use and want a maintenance-free drop-in.
Not Your Match When
The Relistart Group 47 H5 is a better fit for owners on Group 47 chassis who do not need the larger Group 48 footprint.
The second Mighty Max MM-G35 on this list targets a different vehicle: the 2015 Nissan Altima. Same Group 35 footprint, same 12V 55Ah and 650 CCA rating, same 100-minute reserve capacity as the Subaru Forester version. For sedan commuters who rarely push the battery beyond starting and basic accessories, that spec sheet is exactly enough.
It carries the same trade-offs as its sibling: lighter on cranking amps than the Group 47 options, and not designed for winch use. The honest read is that this is a dependable commuter replacement, nothing flashy.
The Value In It
- Direct fitment for 2015 Nissan Altima
- Maintenance-free sealed AGM design
- Strong deep discharge recovery
Less Ideal Details
- 650 CCA trails higher-output competitors
- Group 35 dimensions limit compatibility
Right Fit For
2015 Nissan Altima owners seeking a sealed, no-fuss replacement that matches factory tray dimensions.
Another Choice May Suit
The Mighty Max MM-G35 for Subaru Forester is the equivalent choice for owners outside the Altima fitment.
Matching Battery Specs to the Way You Actually Ride
All terrain vehicles see rougher use than most passenger cars, so the battery you choose should reflect that. The first number to match is the BCI group size (a standardized case dimension set by the Battery Council International that ensures physical fitment), printed on your existing battery or listed in the owner’s manual. Group 35 covers many mid-size sedans and compact vehicles. Group 47 (H5) and Group 48 (H6) cover a wide range of sedans, SUVs, and crossovers. Group 94R (H7) and Group 140R (LN1) fit full-size trucks and European imports respectively. Skipping this step is the single most common reason for a return, so measure the tray first.
What Cold Cranking Amps Actually Means for ATVs
CCA, or cold cranking amps, measures how much current a battery can deliver at 0°F for 30 seconds while maintaining voltage above a set threshold. For trail riders in northern climates, anything below 650 CCA leaves thin margins on cold mornings. Look for 680 CCA or higher if your riding season stretches into late autumn or winter, and pair that with at least 100 minutes of reserve capacity if you run winches or accessory lighting.
Why AGM Construction Matters Off-Road
AGM batteries suspend the electrolyte in fiberglass mats, making them vibration-resistant and spill-proof. That matters on rough trails where a conventional flooded battery would suffer plate damage and acid slosh. For utility quads and side-by-sides exposed to constant shaking, AGM is the practical default.
Warranty Length and Real-World Longevity
A 36-month warranty does not guarantee the battery will last three years, but it does shift replacement risk to the manufacturer. Owners who keep vehicles longer than the typical four-year loan term benefit most from longer warranty windows. Shorter coverage can still make sense on a budget, but factor in the cost of an earlier replacement.
Key Considerations Across These Picks
Pitfalls Shoppers Hit
Matching the group size ranks as the most common misstep. A Group 94R battery simply does not fit a Group 47 tray, no matter how attractive the specs look on paper. CCA mismatch is the next issue: choosing a battery with fewer cold cranking amps than the factory unit can leave you stranded on cold mornings. Finally, terminal polarity catches many first-time installers off guard. Left-negative versus right-positive is a one-character difference that can flip a simple job into a return trip.
What The Higher Tier Buys
Premium-tier batteries earn their pricing through warranty length, plate composition, and cycle-life testing. The MARXON Group 94R and ACDelco Gold 94RAGM both deliver 850 CCA or higher alongside 36-month coverage, which budget alternatives cannot match. The upgrade is worth pursuing for owners in cold climates, those running heavy accessory loads, or anyone planning to keep the vehicle past five years.
Frequently Asked Questions
How long do AGM ATV batteries typically last?
Most AGM batteries in this category last three to five years under normal use, with shorter lifespans in vehicles with constant accessory drain. Cold climates and frequent deep discharges shorten life expectancy noticeably.
Can I install an AGM battery myself?
Most group sizes fit standard trays with basic hand tools, and terminal connections are straightforward. Owners with start-stop vehicles may need a scan tool or battery registration step to reset the charging system, which adds complexity.
What happens if I choose a battery with too few CCA?
A battery with insufficient cold cranking amps may crank slowly on cold mornings or fail to start at all. Replacing it with the correct rating is the only real fix, and the tow bill usually exceeds the cost of getting the right battery initially.
Are higher amp-hour ratings always better?
Higher amp-hour ratings extend accessory runtime but do not improve starting power. For starting-focused applications, CCA matters more than amp-hours, and oversizing can strain charging systems designed for specific loads.
Why do some batteries list both a group number and an H or L code?
Group numbers like 47 or 94R are BCI standards, while codes like H5 or L4 are European DIN equivalents (Deutsches Institut für Normung, the German industrial standards body). Both indicate case dimensions and terminal layout for fitment reference.
The Takeaway
The right battery comes down to three things: the group size that physically fits your tray, the CCA that matches your climate, and the warranty length that fits your ownership horizon. Run through those three before clicking buy, and any of the ten options above will serve you well.
