A 950 cold cranking amp battery can deliver substantial starting power, but the right choice also depends on battery group size, terminal layout, capacity, and your vehicle’s requirements. The Goodyear Group 95R and the Group 65 battery list 950 CCA; the Crown Group 31 also lists 950 CCA and is sold as a four-battery pack. The Mighty Max Group 31 provides 900 CCA, while its Group 26R option is rated at 540 CCA. Check your owner’s manual before choosing.
| Product | Listed CCA | Best For |
|---|---|---|
| Goodyear Group 95R AGM | 950 | Buyers seeking a 950 CCA AGM battery with 100Ah capacity |
| Battery Group 65 | 950 | Buyers whose vehicle specifies Group 65 |
| Crown Group 31 AGM | 950 | Commercial buyers considering a four-battery pack |
| Mighty Max MM-G31 | 900 | Buyers who need Group 31 and can use a lower CCA rating |
| Mighty Max MM-G26R | 540 | Buyers whose vehicle specifies Group 26R and 540 CCA |
Goodyear Group 95R AGM Battery
Best for: Drivers whose vehicle calls for Group 95R and who want a battery rated at 950 CCA. Its listed specifications include 12 volts, 100Ah, and 190 minutes of reserve capacity, making it a high-capacity option among the products here.
The AGM battery is described as maintenance-free and can be mounted in multiple positions, except upside down. The listing also states that it offers up to twice the cycle life of conventional batteries; that is a manufacturer claim, not a guarantee for every vehicle or use pattern.
Limitation: Group 95R is not interchangeable with other group sizes just because their CCA ratings match. Confirm the required group size and installation orientation before purchase.
Group 65 AGM Battery
Best for: Buyers whose vehicle requires a Group 65 battery and lists 950 CCA as an appropriate rating. The product details specify 12 volts, 950 CCA, 74Ah capacity, and 145 minutes of reserve capacity.
The listing identifies an AGM absorbed-glass-mat design and tin-plated brass SAE top terminals. These details can help shoppers compare battery type and terminal style with the original battery and the vehicle’s specifications.
Limitation: The stated length and width are 11.8 and 7.2 inches, but the supplied details do not state height. Confirm full dimensions, terminal position, and fitment before ordering.
Crown Group 31 AGM Battery Pack
Best for: Commercial buyers who need Group 31 batteries and are shopping for multiple units. The listing identifies this as a pack of four, with each battery described as 12 volts, 100Ah, and 950 CCA. It also highlights a sealed, maintenance-free AGM design.
The stated 100Ah capacity provides reserve power in addition to the listed starting output. This option is worth comparing when Group 31 is required for a truck or equipment application and a multi-battery purchase suits the need.
Limitation: This is a four-pack, not a single battery. Confirm the required quantity, group size, and equipment specifications before buying.
Mighty Max MM-G31 AGM Battery
Best for: Buyers who need a Group 31, 12-volt AGM battery and whose application can use 900 CCA rather than a strict 950 CCA minimum. Its listed specifications include 100Ah capacity and 140 minutes of reserve capacity.
The manufacturer describes the battery as sealed and spill-proof, with high discharge output and deep-discharge recovery. Those features may be relevant to shoppers comparing AGM options for starting and reserve-power needs.
Limitation: Its rated 900 CCA is 50 amps below the 950 CCA target. Avoid it if your vehicle or equipment specifically requires at least 950 CCA.
Mighty Max MM-G26R AGM Battery
Best for: Drivers whose vehicle specifically calls for Group 26R and a 540 CCA battery. The product is rated at 12 volts and 45Ah, with an 80-minute reserve capacity.
Its listed features include a sealed, spill-proof AGM design, high discharge output, and deep-discharge recovery. Choose it based on the vehicle’s required group size and electrical specifications, rather than treating it as a 950 CCA alternative.
Limitation: At 540 CCA, this battery does not meet a 950 CCA requirement. It is included as a group-size comparison, not as a match for shoppers who must have 950 CCA.
Buying Guide: How to Choose a 950 CCA Battery
Does the battery group size match your vehicle?
Start with the group size listed in your owner’s manual or on the existing battery. Group 31, 95R, 65, and 26R are different size designations. A battery with the right CCA may still be unsuitable if its dimensions, terminal arrangement, or hold-down configuration do not fit.
Is 950 CCA required or simply preferred?
CCA measures a battery’s starting output under standardized cold-temperature conditions. If your vehicle specifies a minimum, meet or exceed that requirement. Do not assume that a 900 CCA or 540 CCA model is an equivalent substitute for a 950 CCA battery.
How should you compare capacity and reserve time?
CCA describes starting output, while amp-hour capacity and reserve capacity offer other points of comparison. In this selection, listed reserve capacity ranges from 80 to 190 minutes. Compare these figures only after confirming fitment and the vehicle’s battery requirements.
Should you choose AGM?
All five products are described as AGM batteries. Compare their stated voltage, capacity, reserve rating, and terminals with your vehicle’s specifications. Do not rely on battery chemistry alone to confirm compatibility.
Frequently Asked Questions
Which listed batteries are rated at 950 CCA?
The Goodyear Group 95R, the Group 65 battery, and the Crown Group 31 battery list 950 CCA.
Is a 900 CCA battery a substitute for a 950 CCA battery?
Not when the vehicle requires at least 950 CCA. Check the owner’s manual for the minimum starting rating.
Does a higher CCA rating guarantee fitment?
No. Verify group size, dimensions, terminal layout, and the vehicle manufacturer’s requirements.
What does reserve capacity mean?
Reserve capacity is a listed measure of how long a battery can provide power under a specified test condition. It is different from CCA, which measures starting output.
Is the Crown Group 31 listing for one battery?
No. The supplied product name identifies it as a pack of four. Confirm the quantity before purchase.
