1. Optima Batteries 8025-160 25 RedTop: Best Overall
The Optima RedTop is a top-tier AGM battery known for its SpiralCell technology. In our evaluation based on spec sheets and owner feedback, it offers excellent cranking power (720 CCA) and superior vibration resistance, making it a great match for Crosstrek owners who drive on bumpy roads or in cold climates. Many users report it lasting 5-7 years with minimal issues.
However, the Optima RedTop is one of the more expensive options, and its Group 25 size may not be a direct fit for all Crosstrek years, sometimes requiring a tray adapter. If budget is a primary concern or you prefer a simple drop-in replacement, consider a standard Group 35 battery instead.
- SpiralCell AGM design provides exceptional vibration resistance and long life
- 720 CCA delivers reliable starting in cold weather, even below zero
- Maintenance-free and spill-proof, ideal for off-road use
Pros: Excellent vibration resistance for rough terrain; High CCA for cold starts; Long service life with proper care
Cons: Higher price point than flooded batteries; Group 25 may require an adapter or slight modification for some Crosstrek models
2. Odyssey Battery 35-PC1400T: Top Performance
The Odyssey 35-PC1400T is a powerhouse with 850 CCA, making it one of the strongest batteries we compared. Based on manufacturer data and owner reports, it delivers outstanding performance in freezing temperatures and has a reputation for longevity, often lasting 8-10 years in moderate use. Its pure lead AGM construction provides low internal resistance and fast recharge.
That said, this battery is expensive and may be unnecessary for Crosstrek owners in warm regions. Its weight and size require careful handling during installation. If you don’t face extreme cold or high electrical demands, a more affordable AGM like the Optima may be a better value.
- Extremely high 850 CCA for instant starts in extreme cold
- AGM design with 3-10 year service life depending on usage
- Vibration-resistant and completely sealed
Pros: Highest cold cranking amps in its class; Long lifespan when maintained properly; Excellent for extreme weather conditions
Cons: Premium price, often overkill for mild climates; Heavy weight (over 40 lbs) can make installation tricky
3. DieHard Advanced Gold 35AGM: Best Value AGM
The DieHard Advanced Gold 35AGM strikes a solid balance between performance and cost. In our research, it offers 700 CCA and AGM reliability at a price point lower than Optima or Odyssey. Owner feedback is generally positive, with many Crosstrek drivers praising its easy fit and reliable starting in cold weather.
However, this battery may not last as long as higher-end AGM batteries in extreme heat, and some users have reported failure after 3-4 years. If you live in a very hot area or need maximum longevity, consider spending more on a premium AGM. For most daily drivers, this is a great value.
- 700 CCA with AGM technology at a competitive price
- Vibration-resistant and maintenance-free
- 3-year free replacement warranty from DieHard
Pros: Strong performance for the price; AGM benefits without the top-tier cost; Good warranty coverage
Cons: Not as durable as premium AGM options; Some users report shorter lifespan in hot climates
4. ACDelco Gold 35AGM: Reliable AGM
The ACDelco Gold 35AGM is a dependable mid-range AGM battery. Based on spec sheets and owner reviews, it provides sufficient 700 CCA for most climates and fits the Crosstrek without modifications. It is priced competitively and backed by a 30-month warranty, which adds peace of mind.
That said, quality control can be inconsistent, with a few owners reporting batteries dying within two years. It also lacks the extreme durability of Odyssey or Optima. If you want a reliable AGM on a budget, it’s a good choice, but we recommend checking the manufacturing date to ensure freshness.
- 700 CCA AGM with ACDelco quality and 30-month warranty
- Calcium-calcium alloy for extended life
- Spill-proof and vibration-resistant
Pros: Trusted brand with solid warranty; Good cold-cranking performance; Affordable for an AGM
Cons: Some units have reported premature failure; Not as robust as premium AGM batteries
5. EverStart Maxx Lead Acid Automotive Battery (Group 35): Best Budget Flooded
The EverStart Maxx Group 35 is a budget-friendly flooded battery that is popular among Crosstrek owners looking to save money. We compared its specs: 650 CCA is adequate for most climates but may be marginal in extreme cold. Owner feedback is mixed, with many praising the low cost and others noting shorter lifespan (3-4 years).
This battery is not ideal for off-road use or very cold regions due to its lower CCA and vibration sensitivity. It also requires periodic water checks and proper ventilation. If you need a cheap replacement for a mild climate and can handle maintenance, it works. Otherwise, invest in an AGM.
- 650 CCA at a very low price point
- Traditional flooded design with easy availability
- 3-year free replacement warranty from Walmart
Pros: Extremely affordable; Widely available at Walmart stores; Good warranty for the price
Cons: Lower CCA may struggle in severe cold; Flooded design requires occasional maintenance and venting
6. Interstate Batteries MT-35 (Group 35): Trusted Flooded
The Interstate MT-35 is a standard flooded battery that has been a go-to for many Subaru owners. Our research shows it offers 640 CCA, which is sufficient for most daily driving but not ideal for extreme cold. Owner feedback indicates it typically lasts 3-5 years with proper care.
However, it is not as durable as AGM options and can be prone to vibration damage on rough roads. It also requires periodic electrolyte checks. If you want a no-fuss, maintenance-free battery, skip this and go with an AGM. For budget-conscious buyers in mild climates, it’s a decent choice.
- 640 CCA from a well-known battery brand
- Flooded design with 18-month warranty
- Good availability at Interstate dealers
Pros: Reliable brand with consistent quality; Adequate CCA for moderate climates; Easy to find at Interstate locations
Cons: Lower CCA than many competitors; Flooded battery requires maintenance and may leak if tipped
7. Bosch S6551B S6 Flat Plate AGM Battery: Premium AGM Alternative
The Bosch S6551B is a premium AGM battery that offers 760 CCA and robust construction. In our comparison, it stands out for its high performance and Bosch’s reputation. Owner feedback is generally positive, with many noting reliable starting even in freezing temperatures.
However, it comes at a high price, and some Crosstrek owners have reported that the terminal orientation or size requires minor adjustments for a perfect fit. If you want a top-tier AGM and are willing to pay a premium, it’s a strong contender. But for most, the Optima or Odyssey offer similar or better value.
- 760 CCA with flat plate AGM technology
- Vibration-resistant and maintenance-free
- Bosch engineering with 3-year warranty
Pros: High CCA for cold starts; Good build quality and brand reputation; Long warranty period
Cons: Expensive, similar to Odyssey; Some fitment issues reported in earlier Crosstrek models
Frequently Asked Questions
What battery group size does a Subaru Crosstrek need?
The Subaru Crosstrek typically uses a Group 35 battery. Some models may accept a Group 25 with an adapter, but Group 35 is the standard for a direct fit. Always check your owner’s manual or existing battery to confirm.
