Start 6 Months FreeFinding the best battery for a GMC Sierra 1500 starts with a question that has nothing to do with brands: which size does your truck use? The sources we found do not agree.
An owner-forum database lists Group 48 (H6) most often, while a parts guide lists Group 94R (H7) for 2019 to 2025 gas engines and H8/49 for the 3.0L Duramax diesel. Order the wrong one and it may not clear the hold-down, or the terminals may land on the wrong sides.
That is why this guide covers both common sizes. We researched the market, shortlisted candidates, and kept six AGM batteries across Group 48 and Group 94R, including OE-style, high-output and high-vibration designs.
We did not physically test any of them. The rankings rest on manufacturer specifications, the labels on the listing photos and what Sierra and Silverado owners say on forums.
Before you click anything, read the group size, CCA and terminal layout on the battery already in your truck. Match all three, then use the Quick List below.

- GM’s own OE-brand name on the label
- AGM design suits the electrical load of a modern Sierra
- 36-month free-replacement coverage
- Lightest battery on this list at about 45.5 lb
Reasons to avoid
- 760 CCA is below the Bosch and Optima ratings
- Wrong pick if your truck came with a Group 94R
The ACDelco Gold 48AGM earns Best Overall because it is the most straightforward like-for-like replacement for a Sierra 1500 that takes a Group 48 (H6) battery. ACDelco is GM’s own parts brand, the Amazon listing is filed under truck fitment, and the owner-forum battery database we reviewed lists Group 48 more often than any other size. A battery that drops into the stock tray and keeps the terminals where the cables expect them removes most of the ways a swap goes wrong.
The label on the listing photo reads 760 CCA, 120 minutes of reserve capacity and 70 amp-hours, with 36 months of free replacement printed on it. The weight is listed at about 45.5 pounds, the lightest battery in this guide, and it is an AGM, which means a sealed, spill-resistant case built for the electrical demands of a late-model truck with a large touchscreen, a trailer module and accessories. For reference, one parts guide we read puts the factory rating of 2019 to 2025 gas Sierras at 730 CCA, so 760 CCA clears that figure.
Here is the part that matters most, and that many roundups skip. The same parts guide lists Group 94R (H7) for the 2019 to 2025 gas engines and Group H8/49 for the 3.0L Duramax diesel, while the forum database leans toward Group 48. Sources disagree, so this pick is only correct for a truck whose existing battery label says 48 or H6. If yours says 94R, skip to the Bosch or the ACDelco 94RAGM below. If it says H8 or 49, none of the batteries in this guide are the right size.
The honest weakness is output and warranty. At 760 CCA it trails the Bosch and Optima ratings of 800 CCA, and its 36-month term is shorter than Bosch’s four years. Owners who live where winter mornings are brutal, or who run a winch, light bar and big stereo from one battery, may want more margin. If you want the same ACDelco quality in the longer size, see the ACDelco Gold 94RAGM. For more output, the Bosch S6587B is the next stop.
Before you buy: check the group size printed on your current battery. This listing is Group 48 (H6). Trucks fitted with a longer Group 94R (H7) need a different listing, and terminal layout must match.

View at AmazonReasons to buy
- Four-year free replacement, the longest on this list
- 800 CCA and 140-minute reserve capacity
- 80 Ah of capacity for accessory-heavy trucks
- Start-stop ready AGM construction
Reasons to avoid
- Group 94R is longer than a 48, and owners disagree on whether it fits without tray changes
- About 52 lb, noticeably heavier than the ACDelco 48AGM
The Bosch S6587B is here for its warranty and its numbers. The manufacturer lists a four-year free replacement, a full year longer than the ACDelco and Goodyear entries, on a Group 94R AGM rated at 800 CCA, 920 CA, 140 minutes of reserve capacity and 80 amp-hours. For a truck that spends time idling with accessories running, that combination of coverage and capacity is the strongest package in the 94R group.
Bosch lists the case at 315 × 175 × 190 mm (about 12.4 × 6.9 × 7.5 inches) and the weight at about 52 pounds, which makes it noticeably heavier than the ACDelco 48AGM. It is sold as start-stop ready, which matters because many newer trucks use automatic stop-start and are designed around AGM behavior. Owner forums put the reserve capacity gain of a 94R over a Group 48 at roughly 20 minutes, around 140 versus 120, which is the practical reason people choose the longer size.
This is also the size one parts guide lists for 2019 to 2025 Sierra 1500 gas engines (H7/94R), with a factory rating of 730 CCA. The Bosch’s 800 CCA sits above that, so owners of those trucks get extra cold-start margin. We would still ask you to read the label on your own battery before ordering, because the sources we found do not agree on sizes by model year and trim.
The catch is the tray. A 94R is longer than a 48, and the owners we read are split on whether it drops into a Group 48 tray without trimming or an adapter. If your truck shipped with a 94R there is nothing to worry about. If it shipped with a 48, measure first and do not assume the longer battery clears the hold-down and the inner fender. Compared with the ACDelco Gold 94RAGM, choose the Bosch for the extra year of coverage and the ACDelco if you want the GM-branded label.
Before you buy: confirm that your Sierra 1500 uses a Group 94R (H7) and that the terminal layout matches. If your current battery is a Group 48, measure the tray before ordering a 94R.
Best for Vibration and Accessories Battery for GMC Sierra 1500
3. OPTIMA Batteries 8171-767 YellowTop DH6 Dual Purpose AGM Battery
Specifications
Type: AGM, SpiralCell, dual purpose
Group size: DH6 (H6 footprint)
Rated output: 800 CCA · 140 min reserve capacity · 72 Ah (C20)
Size / weight: 10.94 × 6.89 × 7.5 in · about 54 lb
Fitment: Group 48-style trucks; verify tray and hold-down
Warranty: Confirm the term on the Amazon listing

- 800 CCA and 140-minute reserve capacity in a 48-class case
- Spiral-cell design with a rated 15x vibration resistance
- Dual-purpose construction handles deep discharge from accessories
- Pure-lead plates
Reasons to avoid
- About 54 lb, the heaviest here
- Amazon’s fit tool may not list the Sierra, so you must verify tray and terminal match yourself
The OPTIMA YellowTop DH6 is the odd one out on this list, and that is the point. Instead of a flat-plate AGM, it uses Optima’s spiral-cell design with pure-lead plates. The manufacturer rates it at 800 CCA, 140 minutes of reserve capacity and 72 amp-hours at the 20-hour rate, and claims 15 times the vibration resistance of conventional flooded batteries.
That vibration figure earns the label. A truck that sees washboard roads, trails or a trailer most weekends shakes its battery constantly, and plate damage from vibration is a classic reason batteries fail early. The dual-purpose design also tolerates deeper discharges, which helps if you run a winch, work lights or a camping setup with the engine off. Of everything here, this is the battery we would look at first for a working or off-road Sierra.
The listing gives the case at 10.94 × 6.89 × 7.5 inches and the weight at about 54 pounds, the heaviest battery in this guide. The length is shorter than a typical Group 48, which is roughly 12 inches long on the Interstate listing we reviewed. Check that your hold-down can secure a shorter case properly and that the terminals line up. Amazon’s own fit data for this listing categorizes it as a passenger-car battery, so do not rely on the fit checker for a truck.
The trade is weight and certainty. It is about 8 pounds heavier than the ACDelco Gold 48AGM, and we could not confirm the warranty term from the sources we could reach, so read it on the listing before buying. If your truck takes a 94R and you want a different design, the Bosch S6587B is the closer match to the factory size.
Before you buy: the DH6 is a different case size from a standard Group 48. Measure your tray, check the hold-down and compare terminal positions before you order.
Best OE-Style Group 94R Battery for GMC Sierra 1500
4. ACDelco Gold 94RAGM (88864542) Group 94R AGM Battery
Specifications
Type: AGM, maintenance-free
Group size: 94R (H7)
Rated output: 850 CCA · 140 min reserve capacity · 80 Ah (per label)
Weight: About 51.6 lb
Fitment: Group 94R trucks; confirm tray fit
Warranty: 36-month free replacement
Today’s Best Deals
View at AmazonReasons to buy
- GM’s OE-brand label in the 94R size
- 850 CCA and 140-minute reserve capacity per the label
- 80 Ah for accessory-heavy trucks
- 36-month free replacement
Reasons to avoid
- Shorter warranty than the Bosch
- Owner posts disagree on its CCA rating, so read the label on the unit
- 94R length may not fit a Group 48 tray
This is the 94R version of our top pick, and it makes the list for trucks that left the factory with the longer battery. The label on the listing photo reads 850 CCA, 140 minutes of reserve capacity and 80 amp-hours, and the manufacturer lists a weight of about 51.6 pounds, with a 36-month free replacement printed on the label.
A note on the numbers: one owner thread we read gives a lower CCA for ACDelco’s 94R AGM than the label does, so treat 850 CCA as what the listing label shows and confirm it on the unit you receive. Either way the reserve capacity of about 140 minutes matches the Bosch and the Optima and gives it a clear edge over the 120-minute Group 48 batteries. For context, a parts guide lists 730 CCA as the factory rating for 2019 to 2025 gas Sierras, so this battery has headroom over that figure.
The label is the reason to pick it over the Bosch. ACDelco is GM’s own parts brand, so a Sierra owner who wants the replacement to carry the same name as the original part gets that here. If you are replacing a battery that is already a 94R, this is the most direct choice from a brand GM itself uses, and the one that matches the list’s #1 pick in everything but case size.
As with every 94R here, the main question is fitment. The longer case suits a truck designed around it, but owners are split on whether it drops into a Group 48 tray. The warranty is also a year shorter than Bosch’s four-year term. Choose the Bosch S6587B if the fourth year matters to you, or the ACDelco Gold 48AGM if your truck takes the shorter Group 48 size.
Before you buy: confirm that your Sierra 1500 uses a Group 94R (H7) and that your terminals match the listing’s layout.
Best Group 48 Alternative Battery for GMC Sierra 1500

- Matches the Group 48 (H6) size most Sierra owners report
- 760 CCA and 70 Ah, same on-paper numbers as the ACDelco
- Three-year warranty printed on the label
- AGM construction for modern electrical loads
Reasons to avoid
- No spec advantage over the ACDelco Gold 48AGM
- We found very little owner-forum feedback on this specific model
The Goodyear 48-H6-AGM is a Group 48 alternative for readers who want a second option in that size. The label on the listing photo reads 12 volts, 70 amp-hours, 760 CCA and 120 reserve-capacity minutes, with a three-year warranty and start-stop AGM branding. On paper those are the same core numbers as the ACDelco 48AGM, so the choice comes down to brand preference and availability.
It sits fifth because it offers no spec advantage over the pick at #1 and because we found little owner-forum discussion of this specific model. A battery with these numbers is a reasonable replacement for a Sierra that takes a Group 48, but we cannot point to owner reports of how it ages. We would rather say that plainly than dress it up. If you want a battery whose track record you can read about in the forums, the ACDelco and Bosch entries are better documented.
One practical oddity: the Amazon listing sits in an unrelated category (Toys and Games), which can make searches confusing and means the fit checker is no help. Rely on the group size and terminal layout printed on the label, and compare it against the battery in your truck. The weight is not specified in the listing we reviewed, so we left it blank rather than guess.
Three-year coverage matches the ACDelco and the WEIZE and trails the Bosch by a year. If you want a Group 48 with a GM-branded label, go to the ACDelco Gold 48AGM. If you want a Group 48-class battery with more output, look at the OPTIMA YellowTop DH6, keeping in mind its different case size.
Before you buy: confirm that your current battery is a Group 48 (H6) and that the positive and negative terminals sit on the same sides as your old one.

- 80 Ah, 850 CCA and 140-minute reserve capacity on the listing
- About 50.9 lb, lighter than the Bosch and the Optima
- Lists a 36-month warranty
Reasons to avoid
- Far less brand recognition than ACDelco or Bosch
- We found little owner-forum discussion of this specific battery
The WEIZE Platinum 94R is the most speculative pick on the list, and we want to be upfront about it. It lists 12 volts, 80 amp-hours, 850 CCA and 140 minutes of reserve capacity, with a 36-month warranty. The case is listed at 12.4 × 6.89 × 7.48 inches and about 50.9 pounds. Those numbers line up with the ACDelco 94RAGM, though Bosch offers a longer four-year term.
What it lacks is track record. WEIZE does not carry the dealer or OE recognition of ACDelco or Bosch, and we found little owner-forum discussion of this specific battery. That is why it sits last. A strong spec sheet is not proof of long-term durability, and buyers who rely on a battery for towing or cold starts may prefer a brand with a documented history.
It is still worth a place because it gives 94R owners a third option in a size where the choices are narrower than for the Group 48. The label on the listing photo shows Group 94R with an H7 marking, 850 CCA, 140 RC and 80 AH, and a three-year warranty line, which agrees with the listing text. If you shop it, read the most recent reviews, confirm the label reads Group 94R, and keep your receipt in case you need the warranty.
Where it fits best is as an alternative for owners of 2019 to 2025 gas trucks that a parts guide lists as H7/94R. For the same specs under a more familiar label, see the ACDelco Gold 94RAGM. For a longer warranty and a documented brand, see the Bosch S6587B.
Before you buy: confirm that your Sierra 1500 uses a Group 94R (H7) and compare the listing’s case dimensions with your battery tray.

FAQs: Frequently Asked Questions
Recommended Best Deal Products
🛻 What size battery does a GMC Sierra 1500 take?
It depends on the model year and engine, and the sources we found disagree. One parts guide lists Group 94R (H7) with 730 CCA for 2019 to 2025 gas engines and Group H8/49 for the 3.0L Duramax. An owner-forum database lists Group 48 (H6) most often. The reliable answer is the label on the battery already in your truck. Match the group size, the CCA rating and the terminal layout before you order.
🛻 Does a Sierra 1500 need an AGM battery?
If your truck came with an AGM, replace it with an AGM. The parts guide we read states that all 2019 to 2025 engines require an AGM and warns that a conventional flooded battery will fail prematurely, and the six batteries in this guide are all AGM designs. AGM batteries are sealed and spill-resistant, and they are built for the heavy electrical load of a modern truck with stop-start and accessories. Your current battery label will say AGM if the truck was built with one.
🛻 Can I put a Group 94R battery in a Sierra that came with a Group 48?
Maybe, but do not assume it. A 94R is longer than a 48, and the owners we read are split: some report it fits, while others modified the tray or hold-down. The upside is roughly 20 more minutes of reserve capacity in the forum figures we saw, about 140 versus 120. Measure the tray length, check the hold-down clearance and compare the terminal positions before buying. If any of those do not match, stay with the size your truck shipped with.
🛻 What battery does the 3.0L Duramax Sierra use?
According to the parts guide we reviewed, the 3.0L Duramax diesel uses a Group H8/49 battery rated at 850 CCA, which is a different size from the Group 48 and Group 94R batteries in this guide. None of our six picks is the right size for that engine. If you drive the diesel, search specifically for an H8 or Group 49 AGM and confirm it against the label on your existing battery.
🛻 How long does a Sierra 1500 battery last?
There is no single figure, because climate, driving habits and electrical load all matter. Heat and short trips shorten battery life, and a truck that sits unused for weeks can discharge the battery. The warranty terms on this page run from 36 months to four years, which signals what each maker expects from the product, though it is not a promise of how long yours will last. If your battery is several years old and the engine cranks slowly, have it load-tested.
🛻 How many cold cranking amps does a Sierra 1500 need?
Cold cranking amps (CCA) measure how much current a battery delivers at 0°F for 30 seconds. The parts guide we read lists 730 CCA as the factory rating for the 2019 to 2025 gas engines and 850 CCA for the Duramax. The batteries here range from 760 to 850 CCA. Matching the original rating is the right target for most owners, and going higher mainly helps in cold climates or with heavy accessory use.
🛻 Is the Optima YellowTop a good fit for a Sierra 1500?
It can be for owners who run heavy accessories or drive on rough roads, thanks to its spiral-cell design, 800 CCA rating and claimed 15 times the vibration resistance of conventional flooded batteries. But the DH6 case is listed at 10.94 inches long, shorter than a typical Group 48, and Amazon’s fit data does not list it as a truck battery. Verify the tray, hold-down and terminal layout yourself before ordering, and read the warranty term on the listing.
Shopping Tips for Finding the Best Battery for a GMC Sierra 1500 in 2026
🛒 Verify the fitment before anything else
Read the label on your current battery and write down the group size, the CCA rating and which side the positive terminal is on. Then match all three against the listing you are about to buy. This one step prevents most returns, and it matters more than any brand choice because the sources we found disagree on size by year and engine.
🛒 Choose the style that matches your use
AGM batteries suit almost every Sierra, since modern trucks are built around them. Within AGM, the choice is between a conventional flat-plate design like the ACDelco, Bosch, Goodyear and WEIZE and a spiral-cell design like the Optima. If your truck works hard, runs a winch or sees rough roads, the spiral-cell design is worth a look. For daily driving, the flat-plate batteries are the simpler fit.
🛒 Do not trust the Amazon fit checker alone
This is the problem most roundups miss. Two of the listings here are categorized oddly on Amazon: the Optima DH6 as a passenger-car battery and the Goodyear 48-H6-AGM under Toys and Games. Fit checkers on listings like these can be blank or wrong. Use the group size and terminal layout printed on the label, and measure the tray when you are changing sizes.
🛒 Account for accessories and electrical load
A winch, light bar, upgraded stereo or a trailer with its own electrical load all draw from the battery. Reserve capacity, the number of minutes a battery can run a load, matters as much as CCA in those cases. The 94R batteries here list about 140 minutes versus 120 for the Group 48 batteries. If you add accessories, favor more reserve capacity rather than chasing CCA alone.
🛒 Read the rating count, not just the stars
Before you buy any battery, open the listing and look at both the star rating and the number of ratings behind it. A high average from a handful of ratings means less than a slightly lower average from hundreds. We could not verify live ratings for this guide, so make this check yourself, and read the most recent reviews for complaints about early failures.
