Our Picks at a Glance
How To Choose the Best Car Battery Group 35
A Group 35 battery must fit your physical tray. But the specs inside that box vary a lot. Matching CCA, RC, and chemistry ensures reliable starts and long battery life.
Cold Cranking Amps (CCA) — The Starting Power Number
CCA (cold cranking amps) tells you how many amps the battery can deliver at 0°F for 30 seconds while keeping voltage above 7.2 volts. Higher CCA provides stronger cranking power in freezing weather for faster engine turnover. Most Group 35 batteries land between 650 and 850 CCA. If your winters are mild, 650 CCA is plenty; if you regularly see sub-zero temps, aim toward the top of that range.
AGM vs. Flooded — The Chemistry Decision
An AGM (absorbed glass mat) battery uses fiberglass mats to hold the acid in place. This makes it spill-proof and more resistant to vibration than a standard flooded battery. It also handles deeper discharges better. If your car came from the factory with an AGM, you must replace it with another AGM, because the charging system is tuned for that chemistry.
Reserve Capacity (RC) — How Long It Runs If the Alternator Fails
Reserve capacity is the number of minutes a fully charged battery can deliver 25 amps before dropping below 10.5 volts. A 100-minute RC means you have about 100 minutes of accessory power if your alternator dies. Higher RC supports heavy electrical loads and long idling periods, reducing the risk of being stranded.

In‑Depth Reviews
1. Interstate Batteries MTX-35
Our pick — over 4★ from 4,500+ verified ratings; the strongest balance of quality and price.
The Interstate MTX-35 uses pure lead plates to deliver what the brand claims is up to three times the life of a standard flooded battery, so you replace it far less often.
This is a pure lead AGM (absorbed glass mat) design. That material choice matters because pure lead resists corrosion better than lead alloys. The battery holds up longer under the heat and vibration of daily driving. At 42 pounds, it is noticeably heavier than the 37.69-pound Weize below. That extra weight comes from packing more lead into the same Group 35 footprint.
The MTX-35’s VRLA technology makes it spill-proof and maintenance-free. Buyers report it fits perfectly in a 2017 Suburban and a 2019 Prius. One owner noted the install was tight past the radiator overflow and recommended removing that part first. The 36-month warranty backs a brand trusted by automotive stores for over 70 years.
Built to outlast the pack: If you keep a car for the long haul, the extra upfront cost buys longevity. The MTX-35 uses pure lead AGM construction to deliver a 36-month warranty and a service life Interstate says is 2-3X longer than conventional batteries.
The long-haul buyer: This pick suits someone who plans to own their car for years and wants a battery that could outlast that ownership. Its pure lead AGM construction and 36-month warranty justify the premium for those who value reliability above all else. The trade-off: it is the heaviest standard AGM option here at 42 pounds, and the tight fit in some engine bays requires extra patience during installation.
2. Odyssey Battery 35-PC1400T
The Odyssey 35-PC1400T cranks out 850 CCA—200 more than the standard Group 35 battery like the Interstate MTX-35—so your engine starts instantly in brutal cold.
This is the starting-power champion of the Group 35 class. Most Group 35 batteries deliver 650 CCA, but the Odyssey provides 850 CCA. That extra capacity means it spins a cold engine noticeably faster and supports heavier electrical loads and longer accessory runs before draining.
Owners mention this battery lasting 7 and even 9 years in heavy-use applications like trucks with powerful radios. One owner noted a 9-year-old Odyssey in a boat still met its original rating after sitting idle for five months. The up-to-4-year limited full replacement warranty is the longest in this roundup. The battery is rated for up to 400 cycles at 80% depth of discharge. It is also 50 pounds—the Goodyear is 39.7 pounds—because of the dense pure-lead plates inside.
The cold-start monster: At 850 CCA and 65 Ah (amp-hours, a measure of total energy), the Odyssey leads the list on both raw starting power and reserve energy. It is the battery you buy when you never want to hear a slow crank again. One owner reported it lasted 9 years in a truck with heavy radio use.
Reach for this if: You endure sub-zero winters, drive a vehicle with high electrical demands, or simply want the longest-lasting, most powerful Group 35 battery. The 3-10 year service life is class-leading. But this is overkill for a basic commuter; the price and 50-pound weight are significant.
3. Weize Platinum AGM Battery BCI Group 35
The Weize Platinum AGM delivers a full Group 35 spec sheet at 37.69 pounds (the Mighty Max is 41.1 pounds), making it easier to lift and install.
This battery hits the standard 650 CCA (cold cranking amps) and 100 RC (reserve capacity, measured in minutes) that most Group 35 vehicles need. It does so in a 37.69-pound package that is noticeably lighter than the 41.1-pound Mighty Max. For a daily driver, that weight makes the Weize easier to handle without sacrificing the 55 Ah (amp-hour) capacity or the 3-year warranty. Customers note it was a “perfect fit in my 2019 Prius” and arrived fully charged in 3 days, fixing a low 12-volt battery fault.
The AGM design handles a wide operating temperature range from -22°F to 158°F. The low self-discharge rate means it holds its charge well when the car sits for extended periods. The 3-year warranty matches the coverage of most premium brands. One reviewer noted they paid “less than half of local store batteries.” The only catch is that some units have arrived dead (a small but real risk reported in reviews). Weize’s warranty process requires multimeter proof, so you need to test the battery immediately upon arrival.
Why it works
- At 37.69 lb versus the Mighty Max’s 41.1 lb for easier handling
- Full 650 CCA and 100 RC meets all standard Group 35 requirements
- 3-year warranty at a price point that undercuts most local auto parts stores
The small risk
- A few reviewers point out receiving a dead unit, and the warranty claim process requires you to provide multimeter proof
- Designed for starting, not for deep-cycle applications like solar or marine use
The smart value pick: This is for the budget-conscious buyer who still wants the longer life and spill-proof safety of an AGM battery. The 37.69-pound weight, 3-year warranty, and strong buyer feedback on fitment make it a reliable choice for standard sedans and SUVs. Test the voltage with a multimeter as soon as it arrives to avoid a warranty headache.
4. Daakmax Platinum AGM Car Battery Group Size 35
The Daakmax Platinum is built to withstand up to 18 times more vibration than standard batteries, so it holds up better on potholed roads or gravel trails.
This is the only Group 35 battery here that specifically calls out 18X vibration resistance. That matters if your commute involves potholes, gravel, or off-road trails. The 650 CCA (cold cranking amps) and 100 RC (reserve capacity in minutes) match the standard spec. The internal construction uses high-density negative paste for improved conductivity and faster recharge times. At 37 pounds, it ties the Weize for lightness and is noticeably easier to handle than the 42-pound Interstate MTX-35.
Shoppers say it fits a Mercedes-Benz GLC 300 and a Cadillac Escalade ESV perfectly. One owner noted it was “packed better than anything I’ve seen before to prevent any damage.” Another buyer mentioned the handle interferes with installation and recommended it should fold flat. The 3-year warranty covers standard starting battery use. The company explicitly states this is not for deep-cycle applications like solar or marine use.
For rough roads and tight engine bays: The 18X vibration resistance gives this an edge over standard AGM batteries if you drive on unpaved surfaces. The 37-pound weight and 650 CCA make it a competitive all-arounder, but one buyer wished the handle folded flat during install.
Reach for this if: You drive on rough terrain, need a battery that resists vibration damage, or want a well-packaged AGM with a 3-year warranty. It fits a wide range of vehicles from Mercedes to Cadillac. skip it if you plan to use this in a deep-cycle application like a trolling motor or solar setup—this is a starting battery only.
5. Goodyear 35-AGM Platinum Series
The Goodyear 35-AGM brings a household tire brand’s engineering to the Group 35 format with a 3-year warranty and CE certification.
This 650 CCA (cold cranking amps) battery from Goodyear offers the same 55 Ah (amp-hours) capacity and 100-minute reserve capacity as the other AGM options here. But it is slightly heavier at 39.7 pounds than the Weize and Daakmax. That extra weight may come from internal construction that supports a wide temperature range and resistance to shock and vibration. The battery is CE certified (a European safety, health, and environmental mark) and built in an ISO-certified factory.
Buyers report it fits a 2016 E350 aux battery slot and a 2021 Jeep Wrangler Rubicon perfectly. One owner noted it fixed an auto stop/start error. Another buyer mentioned that upgrading from a flooded lead-acid to this AGM made their LED headlamps brighter and flicker-free at idle. That is a real benefit of the higher stable voltage that AGM batteries provide. However, one buyer mentioned a warranty issue where the battery failed at 6 months and Goodyear refused to replace it, directing the customer to Amazon instead—so the 3-year warranty may require persistence to claim.
What stands out
- Known brand name with CE certification and ISO factory production
- Multiple mounting positions (excluding upside down) for flexible installs
- Owners mention it fixes stop/start errors and improves LED headlight stability
The warranty question
- At least one owner reported a 6-month failure with manufacturer refusing to honor the 3-year warranty
- Slightly heavier than the Weize at 39.7 lb vs 37.69 lb
A brand-name AGM upgrade: This battery works well as a drop-in for Wranglers and E-Class cars. But the warranty experience has been inconsistent. One buyer could not get a replacement after a 6-month failure. Keep your documentation and be prepared to push if needed.
6. Autocessking Group Size 35 AGM
The Autocessking Group 35 carries the highest rating in this list at 4.6 stars from 117 ratings, with buyers calling out the value versus local store prices.
This 650 CCA (cold cranking amps), 55 Ah (amp-hours) AGM battery matches the output of the pricier picks here but at a lower entry point. Customers note it “cost half of auto parts store price, well-packed, arrived charged and in perfect condition.” At 38 pounds, it is right in the middle of the weight range and easy to handle during installation. The 3-year warranty from Autocessking covers standard starting battery use. The AGM design resists vibration, corrosion, and extreme temperatures.
Multiple reviewers mentioned that the seller recommends charging the AGM battery with a smart charger before installation, even though it arrives charged. This is good practice for any AGM battery because it ensures the plates are fully saturated before the first heavy discharge. The battery is not designed for deep-cycle applications like solar projects—it is a starting battery meant for cars, SUVs, and trucks.
The budget AGM with a star rating to back it: At 4.6 stars from 117 ratings, the Autocessking is the highest-rated battery in this roundup. Buyers consistently praise the price and packaging. One noted it costs half what a local auto parts store charges for a comparable AGM.
The smart budget move: If you want the benefits of an AGM battery—spill-proof, vibration-resistant, longer life—without paying a premium, this is the pick. The 4.6-star rating and 3-year warranty make it a low-risk entry. Plan to charge this with a smart AGM-compatible charger before first use, as the seller recommends.
7. Mighty Max Battery MM-G35
The Mighty Max MM-G35 tested at 930 CCA on a buyer’s meter—its rated spec is 650 CCA—suggesting strong real-world cranking power.
This is the most intriguing battery in the list. It is rated for 650 CCA, just like most other Group 35 options. But one customer observed measuring over 930 CCA on their tester when the battery first arrived. That kind of headroom means this battery may deliver stronger cranking performance than the spec suggests. It is 41.1 pounds; the Weize is 37.69 pounds. The extra weight likely comes from the internal lead density supporting the higher real-world output.
The catch is that the Mighty Max is not a straightforward drop-in for everyone. One user highlighted the listing was incorrect for a 2000 Tacoma because the terminals were wrong. Another buyer reported the battery was advertised as i-ELOOP compatible with a Mazda6 Grand Touring but could actually harm the car’s smart charging system. The 1-year manufacturer warranty is also shorter than the 3-year warranties on every other pick here. Buyers who have had success report it works great for a Generac generator and offers strong value compared to a wholesale store AGM battery.
The hidden upside
- A buyer’s tester measured 930 CCA, far above the rated 650 CCA, suggesting strong real-world starting power
- At 41.1 lb it is the heaviest standard AGM here, which correlates with more internal lead
- Sealed, spill-proof AGM design with multiple mounting position options
Serious caveats
- Fitment is not universal—reported terminal mismatch for Tacoma and i-ELOOP compatibility issues for Mazda6
- Only a 1-year warranty, far shorter than the 3-year coverage on competitors
- At 41.1 lb versus the Weize’s 37.69 lb, which makes it harder to install in tight engine bays
For the tester-verified output seeker: If you have tools to confirm actual CCA and want a battery that measured well above its rating, the Mighty Max is worth a look. Use it in vehicles where the fitment is confirmed, not where you need to guess. pass on it if you need a guaranteed fit for a modern start-stop or i-ELOOP car, or you want the longer warranty that every other battery on this list offers.
Understanding the Specs
Cold Cranking Amps (CCA)
CCA (cold cranking amps) measures the battery’s ability to start an engine in cold temperatures. Specifically, it is the number of amps a 12-volt battery can deliver at 0°F for 30 seconds while maintaining at least 7.2 volts. For a standard Group 35 battery, 650 CCA is the baseline. Options like the Odyssey deliver 850 CCA for much stronger winter performance, so your engine turns over faster in sub-zero weather. If you live in a cold climate, higher CCA directly translates to more reliable starts. In warmer climates, 650 CCA is typically sufficient for most passenger cars and SUVs.
Reserve Capacity (RC)
Reserve capacity (RC) tells you how long the battery can run your car’s essential electrical systems if the alternator fails. It is measured in minutes at 25 amps down to 10.5 volts. Most Group 35 batteries provide 100 minutes of reserve capacity. That is enough to keep your engine running and lights on for a short distance to a repair shop. A higher RC value is useful for vehicles with heavy accessory loads like upgraded audio systems, winches, or additional lighting, where you rely on the battery even when the alternator is working.
