Check your car first

• 2023 5.3L V8: GM's own 2023 chart confirms AGM and 730 CCA; group size from Interstate.
• 2023 6.2L V8: GM's own 2023 chart confirms AGM and 730 CCA; group size from Interstate.
• 2019–2020 2.7L Turbo: Mopar's guide lists 720 CCA; Interstate lists 730. We show the higher figure.
• 2014–2019 5.3L and 6.2L V8, primary battery (2019 = 1500 LD): Some trucks also have a second (auxiliary) Group 48 battery.
• 2010–2013 6.0L V8 Hybrid, 12V battery: Both sources agree on Group 48 (H6). They list different CCA figures, so we don't show one.
• 2009–2013 4.3L V6, 4.8L, 5.3L and 6.2L V8, optional battery: Some trucks came with a higher-rated optional battery (same group size). If yours has one, replace like for like.
• 2000–2005 4.3L V6, 4.8L and 5.3L V8, optional battery: Some trucks came with a higher-rated optional battery (same group size). If yours has one, replace like for like.
• Some rows depend on trim or equipment (see the version column in the table). If you're not sure which applies, match the battery already in your car.
• Not shown yet: 2007 (old-body 'Classic' and new-body trucks were both sold as 2007 models, with different sizes), 2009 Hybrid (one source), 6.0L, 8.1L and diesel trucks (mostly HD models, not covered here), 2021-2022 (one source only), 3.0L Duramax diesel (one group-size source), 2023 2.7L and 2024+ (GM lists AGM and CCA but not group size).

Confirm in your owner's manual. Battery fitment can change with engine, trim, option packages, market (US vs. Canada) and mid-year production changes. Before you buy, check the label on the battery that's in your car now and your owner's manual.

How to replace the battery

Tools: 10 mm wrench or socket (some hold-downs need 12 or 13 mm or an extension), gloves, eye protection, terminal brush. Time: about 15–30 minutes for an under-hood battery; longer if it's in the trunk or under a seat.

1. Park, turn everything off and take the key or fob out of the car.
2. Disconnect the negative (–) cable first, then the positive (+).
3. Remove the hold-down and lift the battery out. Batteries are heavy (often 35–60 lb); lift with your legs.
4. Clean the tray and cable ends. Set in the new battery with the posts on the same sides as the old one.
5. Fit the hold-down, connect positive (+) first, then negative (–). Tighten until the clamps don't twist by hand.
6. If your car has a vent tube on the battery (common for trunk or cabin batteries), reconnect it.
7. Start the car. Some newer vehicles with a battery monitor need a reset or registration after a new battery. Your owner's manual explains it; a parts store or dealer can do it if needed.

Most parts stores take old batteries for recycling and usually refund a core charge.
