The GranTurismo battery decision starts with the model year and the battery actually installed in the car. Current vehicle catalogues show Group 49/H8 AGM choices for several GranTurismo applications, but the listings below span 2013, 2017 and 2018 rather than proving one battery fits every year. The first two appear on a 2018 vehicle selector, the Duracell on a 2013 MC 4.7L selector, and the ACDelco and Motorcraft on a 2017 selector. Compare the old battery label, cable position, hold-down, dimensions and any registration procedure before ordering. Prices exclude any listed core charge and installation.

The picks, in detail
Odyssey ODP-AGM49H8L5
AutoZone offers this Odyssey as a 2018 GranTurismo battery. Its listed 950 CCA and 180-minute reserve capacity are the highest figures among these five, at a substantially higher price. It suits a buyer who wants the longer reserve rating and has confirmed the Group 49 case in the car.
- Group 49/H8 AGM case
- 950 CCA rating
- 180-minute reserve capacity
- Highest listed CCA in this set
- 180-minute reserve specification
- Highest upfront price; core charge extra
Duralast Platinum H8-AGM
Duralast Platinum H8-AGM is another battery shown on AutoZone’s 2018 GranTurismo selector. Its 900 CCA and four-year warranty make it a lower-cost alternative to the Odyssey on the same vehicle listing. Confirm the car has the catalogued H8 tray and compatible terminals.
- H8 AGM configuration
- 900 CCA output
- Four-year listed warranty
- 2018 vehicle-selector listing
- Costs less than the Odyssey choice
- 900 CCA trails Odyssey’s 950 CCA
Duracell Ultra SLI49AGM
Batteries Plus lists SLI49AGM as the primary battery for the 2013 GranTurismo MC 4.7L. The 92 Ah capacity and 850 CCA are documented for that application, giving MC owners a model-year-specific starting point. Its fitment claim should not be extended to every GranTurismo without another lookup.

- Group 49 AGM, 92 Ah
- 850 CCA with SAE posts
- Direct 2013 MC fitment listing

ACDelco 49AGM
O’Reilly lists ACDelco 49AGM for the 2017 GranTurismo, while Walmart carries the exact battery at a current U.S. price. At 900 CCA and a 160-minute reserve, it is the least expensive listed battery here. Check the store’s core charge and the old battery’s terminal orientation before purchase.

Motorcraft BAGM49H8
The 2017 GranTurismo catalogue at O’Reilly includes Motorcraft BAGM49H8, and AutoNation lists the exact part for sale. It provides an 850 CCA H8/49 AGM option with a 160-minute reserve and published case dimensions. The separate $18 core charge increases the checkout cost until an old battery is returned.
- H8/Group 49 AGM case
- 850 CCA and 160-minute reserve
- 13 15/16 x 6 15/16 x 7 1/2 in case

Buying tips
- Use the vehicle selector for the exact GranTurismo model year and engine.
- Read the installed battery label before relying on a Group 49/H8 catalogue result.
- Compare battery height, hold-down and post orientation with the old unit.
- Ask the installer whether battery registration or system reset is needed.
- Account for a refundable core charge when comparing checkout prices.
- Do not mix the 2013 MC, 2017 and 2018 fitment claims.
