The best Group 86 car battery depends on your vehicle’s required battery type, climate, and starting-power needs. Interstate’s MT-86 is a conventional flooded option for hot to moderate climates, while the MTP-86 offers higher cold-cranking amps for colder conditions. A listed lithium Group 86 battery provides a different chemistry, and the two Group 96R options below are comparison choices—not direct Group 86 replacements. Always confirm size, terminal layout, and vehicle fitment before buying.
| Battery | Type and key rating | Best suited for |
|---|---|---|
| Interstate MT-86 | Flooded, 525 CCA, 90-minute reserve | Hot to moderate climates |
| Interstate MTP-86 | Flooded, 650 CCA, 95-minute reserve | Cold to moderate climates |
| LITHIUM Group 86 | LiFePO4, 40Ah, 12.8V | Buyers considering lithium chemistry |
| Weize Group 96R | AGM, 600 CCA, 52Ah | Vehicles specified for Group 96R AGM |
| Autocessking Group 96R | AGM, 600 CCA, 52Ah | Start-stop applications requiring Group 96R |
Interstate MT-86: Best For Hot Climates
The Interstate MT-86 is a conventional flooded Group 86 battery rated at 525 cold-cranking amps (CCA) and 90 minutes of reserve capacity. The manufacturer describes the MT series as suited to hot to moderate climates and notes its high electrolyte-to-lead ratio.
Best for: Drivers whose vehicles call for a Group 86 flooded battery and who want a straightforward option for warmer or moderate conditions. Its listed 525 CCA and reserve rating make it easy to compare with the higher-output MTP-86.
Limitation: This model has lower CCA and reserve capacity than the MTP-86. It is not an AGM battery, so it may not suit vehicles that require AGM chemistry. Confirm fitment for your exact vehicle.
Interstate MTP-86: Best For Higher CCA
The Interstate MTP-86 is a flooded Group 86 battery with 650 CCA and 95 minutes of reserve capacity. Interstate positions this model for cold to moderate climates and says its higher CCA and reserve ratings distinguish it from the MT-86. The listed warranty is 30 months.
Best for: Buyers who need a Group 86 flooded battery and prioritize higher listed starting power, particularly in colder conditions. Compared with the MT-86, it offers 125 more CCA and five additional minutes of reserve capacity.
Limitation: It is a conventional flooded battery, not AGM. Do not choose it if your vehicle requires an AGM battery. Check the vehicle fitment listing and terminal arrangement before ordering.
LITHIUM Group 86: Best For Lithium Chemistry
This maintenance-free Group 86 option uses LiFePO4 chemistry and is listed as 12.8V, 40Ah, and 512Wh. Its product title states 1,200 CCA. Features include a built-in battery management system intended to protect against overcharge, overdischarge, overcurrent, short circuits, and low or high temperatures. The listed dimensions are 9.06 × 6.81 × 7.99 inches.
Best for: Drivers specifically considering a lithium Group 86 battery and willing to verify that their vehicle’s charging system and requirements suit this chemistry.
Limitation: Lithium chemistry is not automatically interchangeable with a conventional flooded or AGM battery. Confirm vehicle compatibility, dimensions, and left-negative/right-positive terminal orientation before purchase.
Weize Group 96R AGM: Best For 96R Vehicles
This Weize Platinum battery is Group 96R, not Group 86. It is an AGM model rated at 12V, 52Ah, 600 CCA, and 90 minutes of reserve capacity. Listed dimensions are 9.53 × 6.89 × 6.89 inches, with tapered terminals and negative on the left. The product states a 36-month warranty.
Best for: A vehicle specifically requiring a Group 96R AGM battery. Its AGM design and listed ratings make it a relevant alternative only when the vehicle’s required size and battery type match.
Limitation: Group 96R dimensions differ from the listed Group 86 lithium battery, and the product is not identified as Group 86. Do not assume it will fit a Group 86 battery tray or vehicle.
Autocessking Group 96R AGM: Best For Start-Stop
The Autocessking battery is a Group 96R start-stop AGM model rated at 12V, 52Ah, 600 CCA, and 90 minutes of reserve capacity. Its dimensions are 9.53 × 6.89 × 6.89 inches, with tapered terminals and negative on the left. The product describes its glass-mat construction as helping contain acid and reduce spills and corrosion.
Best for: Buyers whose vehicle calls for a Group 96R AGM battery and whose application requires a start-stop battery. Its ratings match the Weize model’s listed CCA, capacity, and reserve time.
Limitation: This is not a Group 86 battery. Verify the vehicle’s specified battery group, AGM requirement, dimensions, and terminal position rather than relying on similar electrical ratings.
Buying Guide: How To Choose A Group 86 Battery
Does Group 86 Have To Match Exactly?
Use the battery group size specified for your vehicle unless its manufacturer or a qualified technician confirms another size fits. Group size relates to physical fit and terminal placement, not just voltage. The Group 96R batteries in this list are not direct Group 86 replacements based on the supplied product details.
Should You Choose Flooded, AGM, Or Lithium?
Match the chemistry recommended for your vehicle. The Interstate MT-86 and MTP-86 are conventional flooded batteries. The Weize and Autocessking products are AGM but Group 96R. The LITHIUM product is LiFePO4. A different chemistry may not be appropriate for every vehicle, so check the owner’s manual and charging-system requirements.
How Much CCA And Reserve Capacity Do You Need?
CCA indicates a battery’s rated starting output in cold conditions; reserve capacity indicates how long it can supply power under a defined load. Among the listed Group 86 options, the MTP-86 has the highest stated CCA and reserve capacity. Choose ratings that meet or exceed your vehicle’s requirements, rather than selecting solely by the largest number.
What Fitment Details Should You Verify?
Compare the battery’s group size, dimensions, terminal orientation, and chemistry with the current battery and vehicle specifications. Confirmed fitment matters even when a listing names your vehicle, because year, engine, and equipment can affect battery requirements.
Frequently Asked Questions
What does Group 86 mean on a car battery?
Group 86 identifies a battery size category. Check the vehicle’s fitment requirements because size, terminal layout, and chemistry all affect whether a battery is suitable.
Which listed Group 86 battery has the highest CCA?
The Interstate MTP-86 is listed at 650 CCA, compared with 525 CCA for the Interstate MT-86. The lithium product title lists 1,200 CCA, but confirm its suitability for your vehicle’s electrical system.
Can a Group 96R battery replace a Group 86 battery?
Not automatically. Group 96R is a different size designation. Use it only if vehicle-specific fitment information confirms it is suitable.
Can I replace an AGM battery with a flooded battery?
Do not assume you can. The supplied Weize product information advises continuing to use AGM when the original battery is AGM. Follow your vehicle manufacturer’s requirements.
What should I check before ordering?
Verify battery group, chemistry, dimensions, terminal position, and vehicle fitment. These checks help prevent physical-fit and electrical-compatibility problems.
