Buying the best battery for a Chevy Silverado 1500 is harder than it should be. GM has used at least four battery groups across the generations, newer trucks want an AGM with a battery management reset, and online fitment charts often disagree with each other.

1. ACDelco Gold 94RAGM AGM Automotive BCI Group 94R Battery (GM 88864542)
Recommended Best Deal Products
The exact Group 94R AGM that GM specifies for most 2019 and newer Silverado 1500s, and the safest single choice on this list.
| BCI group | 94R (H7) |
| Technology | AGM |
| Cold cranking amps | 850 CCA (1,020 CA) |
| Reserve capacity | 140 minutes |
| Capacity | 80 Ah |
| Dimensions (L×W×H) | 12.4 × 6.9 × 7.5 in |
| Weight | about 51.6 lb |
| Warranty | 36 months |
| Rating | 4.5/5 from roughly 1,700 ratings |
✔ Pros
- Matches the GM part number (88864542) used in most 2019+ trucks
- AGM design suits stop-start and heavy accessory loads
- 850 CCA with 140 minutes of reserve capacity
- Backed by a 36-month warranty
✘ Cons
- Heavy at about 51.6 lb, so lifting it into the tray takes some effort
- AGM construction means a charger set to the wrong profile can shorten its life
This is the battery GM itself lists for the 2019 and newer Silverado 1500 with the 2.7L turbo, 5.3L or 6.2L engine. It earns Best Overall because it removes guesswork: same BCI group, same AGM chemistry and the same terminal layout as the original.
On paper it delivers 850 cold cranking amps (1,020 cranking amps at 32°F) and 140 minutes of reserve capacity from an 80 Ah case measuring 12.4 by 6.9 by 7.5 inches. That is comfortably above the roughly 730 CCA that several fitment sources report for the factory unit, which matters most on winter mornings and when you run a winch, light bar or a loaded infotainment system with the engine off.
The honest drawbacks are weight and the need to treat it properly. At around 51.6 lb it is not a one-handed job, and like any AGM it wants a charger with an AGM profile. Plan on a battery management system (BMS) reset after the swap, as covered in the buying guide below.
If your truck has a high-demand load or you frequently leave it parked for days, compare it with the high-reserve variant in card 3, which adds 10 more minutes of reserve for the same case size.
Who should buy it: Owners of 2019+ Silverado 1500s with the 2.7L, 5.3L or 6.2L engine who want the factory-correct replacement.

Listen Free for 30 Days2. ACDelco Gold 48AGM AGM Automotive BCI Group 48 Battery (GM 88864541)
The right AGM upgrade when your Silverado tray and cables are built for a Group 48 (H6) battery.
| BCI group | 48 (H6) |
| Technology | AGM |
| Cold cranking amps | 760 CCA (880 CA) |
| Reserve capacity | 120 minutes |
| Capacity | 70 Ah |
| Dimensions (L×W×H) | 10.9 × 6.9 × 7.5 in |
| Weight | about 46 lb |
| Warranty | 36 months |
| Rating | 4.5/5 from roughly 2,100 ratings |
✔ Pros
- Correct size for trucks that use a Group 48 tray
- 760 CCA is strong for the H6 footprint
- AGM build tolerates vibration and deep cycling
- Same 36-month warranty as the other ACDelco Gold units
✘ Cons
- Not interchangeable with the taller 94R in trucks built around that group
- Lower reserve capacity (120 minutes) than the 94R and 49 options
Not every Silverado 1500 takes a Group 94R. Many 2014 to 2018 trucks and the 4.3L V6 models of later years are reported to use a Group 48, and this ACDelco is the AGM version of that size, sold under GM part number 88864541.
It supplies 760 CCA (880 cranking amps) and 120 minutes of reserve capacity from a 70 Ah case measuring 10.9 by 6.9 by 7.5 inches. Because the case is shorter than a 94R, it drops into a Group 48 tray with the hold-down where the original expects it.
The trade-off is capacity. If you added accessories, or your truck has stop-start, the extra reserve of a 94R or 49 is worth having, but only if the tray and cables physically allow it.
If your truck uses the larger 94R, skip this one and go to card 1 or card 3.
Who should buy it: Silverado owners whose current battery is stamped Group 48 or H6 and who want an AGM replacement.

See Annual Plans3. ACDelco Gold 94RAGMHR High Reserve AGM BCI Group 94R Battery (GM 88866098)
Recommended Best Deal Products
A Group 94R AGM tuned for extra reserve capacity, aimed at trucks that sit with accessories running.
| BCI group | 94R (H7) |
| Technology | AGM, high reserve |
| Cold cranking amps | 850 CCA (1,000 CA) |
| Reserve capacity | 150 minutes |
| Dimensions (L×W×H) | 12.4 × 6.9 × 7.5 in |
| Weight | about 51.5 lb |
| Warranty | — (confirm on the listing) |
| Rating | Not confirmed |
✔ Pros
- 150 minutes of reserve capacity, the highest of any 94R here
- Same footprint as the standard 94R
- 850 CCA matches the standard ACDelco 94R AGM
✘ Cons
- Warranty term and review count were not confirmed for this listing
- Offers little over card 1 for a stock truck with light accessory use
The high-reserve version shares its case size with the standard 94RAGM, so it fits wherever a Group 94R fits. GM lists it as part number 88866098.
Its 850 CCA rating (1,000 cranking amps) is essentially the same as the standard unit, but reserve capacity climbs to 150 minutes. That extra buffer is the reason to choose it: more time with the engine off before the truck struggles to start.
It is not automatically better, though. For a stock truck driven daily, the difference is marginal, and we could not confirm a warranty term or an aggregate rating for this listing, so check both on Amazon before buying.
Tow rigs, work trucks that idle with lights and tools running, and vehicles parked for days at a time are the natural fit; everyone else can stay with card 1.
Who should buy it: Owners who run accessories with the engine off, or who park the truck for long stretches.

4. ACDelco Gold 49AGM AGM Automotive BCI Group 49 Battery (GM 88864539)
A larger Group 49 AGM that fits the 2019 and newer 3.0L Duramax trucks, where the bigger engine asks more of the battery.
| BCI group | 49 (H8) |
| Technology | AGM |
| Cold cranking amps | 900 CCA |
| Reserve capacity | 160 minutes |
| Capacity | about 90–95 Ah |
| Dimensions (L×W×H) | 13.9 × 6.9 × 7.5 in |
| Weight | about 58.6 lb |
| Warranty | 36 months |
✔ Pros
- 900 CCA is the highest rating on this list
- 160 minutes of reserve capacity
- Correct group for 2019+ 3.0L Duramax trucks
✘ Cons
- At 13.9 in long it will not fit a tray built for a 94R or 48
- Heaviest battery here at about 58.6 lb
GM fits the 2019 and newer Silverado 1500 with the 3.0L Duramax turbo-diesel with a Group 49 AGM, and this ACDelco matches that specification under part number 88864539.
Its numbers reflect the diesel’s demands: 900 CCA and 160 minutes of reserve capacity, both the top figures in this roundup, from a case about 13.9 inches long.
That size is also the limit. It is a poor choice for a gas Silverado, because the tray, hold-down and cable reach are set up for a shorter case.
Owners of gas trucks should look at card 1 instead.
Who should buy it: Owners of 2019+ Silverado 1500s with the 3.0L Duramax diesel.

5. OPTIMA Batteries 8004-003 34/78 RedTop Starting Battery
A spiral-cell AGM with dual SAE and GM side terminals that suits older Silverados designed around Group 34 or 78.
| BCI group | 34/78 |
| Technology | Spiral-cell AGM |
| Cold cranking amps | 800 CCA |
| Reserve capacity | 100 minutes |
| Capacity | 50 Ah (C20) |
| Dimensions (L×W×H) | 10.06 × 6.94 × 7.88 in |
| Weight | about 38.8 lb |
| Terminals | Dual SAE post and GM side terminal |
| Warranty | — (confirm on the listing) |
| Rating | 4.4/5 from roughly 1,900 ratings |
✔ Pros
- Dual SAE and GM side terminals fit older cable layouts
- Spiral-cell construction resists vibration
- 800 CCA in a compact, lighter case (about 38.8 lb)
✘ Cons
- Lower reserve capacity (100 minutes) than the ACDelco options
- Not intended for 2019+ trucks that require a 94R or 49 with BMS
The RedTop is the best fit for older Silverados. Fitment sources commonly place Group 34, 78 or 34/78 in 1999 to 2013 trucks, and the RedTop’s dual terminals let it work with both post and side-terminal cables.
It is rated at 800 CCA and 100 minutes of reserve capacity in a case measuring 10.06 by 6.94 by 7.88 inches. Spiral-wound cells hold up well to vibration, which suits a truck that sees gravel and washboard roads.
The limits are reserve capacity, which trails the ACDelco batteries, and modern-truck compatibility. It is the wrong pick for a 2019 or newer Silverado.
If your truck is a 2014 to 2018 model, check the group on your current battery first; card 2 may be the better match.
Who should buy it: Owners of 1999–2013 Silverado 1500s that use Group 34, 78 or 34/78.

6. Weize Platinum AGM Battery BCI Group 94R (H7), 12V 80Ah 850CCA
A Group 94R AGM from a different manufacturer for owners who want an alternative to ACDelco.
| BCI group | 94R (H7) |
| Technology | AGM |
| Cold cranking amps | 850 CCA |
| Reserve capacity | 140 minutes |
| Capacity | 80 Ah |
| Dimensions (L×W×H) | 12.4 × 6.89 × 7.48 in |
| Terminals | Left negative, right positive |
| Warranty | 36 months |
| Rating | Not confirmed |
✔ Pros
- Matches ACDelco’s 94R numbers: 80 Ah, 850 CCA and 140 minutes of reserve
- 36-month warranty
- Same 94R footprint, so it fits the same trays
✘ Cons
- Little independent testing or owner-forum history compared with ACDelco or OPTIMA
- Terminal orientation should be verified against your truck before ordering
Weize lists a Group 94R AGM with the same headline numbers as the ACDelco: 80 Ah, 850 CCA and 140 minutes of reserve capacity in a 12.4 by 6.89 by 7.48 inch case.
The appeal is choice. If ACDelco is unavailable, or you simply want a second option, this fills the same slot with a 36-month warranty.
The downside is track record. Independent reviews and long-term owner reports are thin, so we rank it below the GM-branded battery. Confirm that the left-negative, right-positive orientation matches your truck’s cables.
Compared with card 7, it is the better documented of the two lesser-known 94R options.
Who should buy it: Owners who need a 94R AGM and prefer a non-ACDelco brand.

7. Mighty Max Battery MM-H7 (Group 94R) 12V 80Ah 850CCA AGM Battery
Another 94R AGM alternative, and the only one here that ships with mounting screws.
| BCI group | 94R (H7) |
| Technology | AGM |
| Cold cranking amps | 850 CCA |
| Reserve capacity | 140 minutes |
| Capacity | 80 Ah |
| Dimensions (L×W×H) | 12.50 × 6.88 × 7.48 in |
| Included | Mounting screws (harness not included) |
| Warranty | 3 years |
| Rating | Not confirmed |
✔ Pros
- Same 94R specs as the ACDelco: 80 Ah, 850 CCA and 140 minutes
- 3-year warranty
- Mounting screws included
✘ Cons
- Very little independent testing available
- Wiring harness is not included
The Mighty Max MM-H7 matches the ACDelco’s numbers on paper: 80 Ah, 850 CCA and 140 minutes of reserve capacity, with a 3-year warranty.
It also ships with mounting screws, a small extra, though the wiring harness is not included.
Like the Weize, it comes from a brand with far less independent coverage than ACDelco or OPTIMA, so the spec sheet is doing most of the talking. We rank it last among the 94R options for that reason.
If you are choosing between the two alternatives, look at warranty terms and terminal layout on the day you order.
Who should buy it: Owners who want a 94R AGM from a lesser-known brand and are comfortable with limited independent reviews.

8. Weize Platinum AGM Battery BCI Group 48 (H6), 12V 70Ah 760CCA
A Group 48 AGM alternative, but its own listing gives conflicting specs, so read the label before you buy.
| BCI group | 48 (H6) |
| Technology | AGM |
| Cold cranking amps | 760 CCA (per title)* |
| Reserve capacity | 120 minutes (per title)* |
| Capacity | 70 Ah (per title)* |
| Dimensions (L×W×H) | 10.94 × 6.89 × 7.48 in |
| Warranty | — (confirm on the listing) |
| Rating | Not confirmed |
✔ Pros
- Group 48 footprint fits H6 trays
- AGM construction suits vibration and cycling
- Gives Group 48 owners a non-ACDelco option
✘ Cons
- The listing title says 70Ah/760 CCA/120 RC while its description gives 60Ah/680 CCA, so the true rating is unclear
- Little independent testing or owner history
This Weize battery is the Group 48 counterpart to the 94R above and shares the same 10.94 by 6.89 by 7.48 inch footprint class as an H6.
Its title claims 70 Ah, 760 CCA and 120 minutes of reserve capacity, which would match the ACDelco 48AGM. However, the product description on the same listing states 60 Ah and 680 CCA. We could not resolve that discrepancy, so the asterisked figures should be treated as unconfirmed.
That inconsistency is the main reason it sits at the bottom of the list. If the lower figures turn out to be right, the battery is meaningfully weaker than card 2.
For most Group 48 owners, card 2 remains the safer choice.
Who should buy it: Group 48 owners who want an alternative to ACDelco and will verify the label figures on arrival.
Availability last checked September 2026.
What to Look for in a Battery for a Chevy Silverado 1500
Match the BCI Group Size First
The group number sets the case length, width and terminal position. A Group 94R (H7) is about 12.4 inches long, a Group 48 (H6) about 10.9 and a Group 49 (H8) about 13.9. If the case is off by even an inch, the hold-down and cables will not line up. Read the label on your current battery before you order.
AGM Is Not Optional on Newer Trucks
Trucks with automatic stop-start, and most 2019 and newer Silverados, are designed around an AGM battery. A conventional flooded battery in that position tends to age faster because the charging system expects the AGM’s lower internal resistance.
Read CCA in Context
Cold cranking amps tell you how much current a battery can deliver at 0°F. More is better in cold climates, but do not chase a number at the expense of fit. A correct-size 760 CCA battery beats a 900 CCA one that will not sit in the tray.
Reserve Capacity Matters for Accessories
Reserve capacity is the minutes a battery can supply 25 amps before dropping to 10.5 volts. Trucks with winches, aftermarket lighting or a dash camera left on will use it more often than a stock commuter.
Check the Terminals and Tray
Confirm which side the positive terminal sits on, and whether your truck uses top posts or GM-style side terminals. Older trucks often use side terminals, which is why the OPTIMA’s dual terminals are useful.
Plan for a Battery Management System Reset
Many newer GM trucks track battery age and state of charge. After installing a new battery, the system may need a reset or relearn so that it stops applying the old battery’s charging profile. Dealers and many independent shops can do this; the procedure is in your owner’s manual or a GM service bulletin.
Which Battery Fits Your Silverado 1500 by Year
Fitment sources do not always agree, so treat this as a starting point and confirm against the label on your battery.
| Model Years and Engine | Commonly Reported Group | Notes |
|---|---|---|
| 2019+ with 2.7L, 5.3L or 6.2L | 94R AGM | Factory unit is commonly cited at about 730 CCA |
| 2019+ with 3.0L Duramax | 49 AGM | Factory rating is about 850 CCA |
| 2019+ with 4.3L V6 | 48 | Verify on your current battery |
| 2014–2018 | 48 or 94R | Depends on engine and trim |
| 2007–2013 | 78, 34/78 or 48 | Check tray and terminal type |
| 1999–2006 | 75 or 78 | Side-terminal designs are common |
Common Mistakes to Avoid
- Buying by year alone. Two trucks of the same year can use different groups depending on engine and options.
- Installing a flooded battery in a truck that came with AGM.
- Skipping the battery management reset on a newer truck.
- Choosing the highest CCA number without checking the case length.
- Charging an AGM with a charger that has no AGM mode.
Frequently Asked Questions
What size battery does a Chevy Silverado 1500 use?
It depends on the year and engine. Many 2019 and newer gas trucks use a Group 94R (H7), 3.0L Duramax trucks use a Group 49, and many earlier trucks use a Group 48, 78 or 34/78. Check the label on your current battery to be sure.
Does a Silverado 1500 need an AGM battery?
Most 2019 and newer Silverados do, especially those with stop-start. AGM batteries handle frequent restarts and heavy electrical loads better than flooded ones. Older trucks without stop-start can run either type, though AGM is a reasonable upgrade.
How many CCA do I need for a Silverado 1500?
Match or exceed the factory rating. The original battery in newer gas trucks is often cited at around 730 CCA, and the 850 CCA options here clear that. Fit and group size should be settled first.
How long does a Silverado battery last?
Most last about three to five years, depending on climate, driving habits and electrical load. Heat shortens battery life more than cold does. A load test at an auto parts store will tell you where yours stands.
Do I need to reset the computer after changing the battery?
Many newer GM trucks need a battery management system reset so the truck knows a new battery is installed. Skipping it can cause the charging system to treat the new battery like an old one. Check your owner’s manual or ask the shop.
Is ACDelco the same as the original GM battery?
ACDelco is GM’s parts brand, and the batteries here carry GM part numbers such as 88864542 and 88864541. That is why they are the closest match to what came in the truck. Other brands can meet the same group and specs but are not GM-branded.
Our Verdict
For most 2019 and newer gas Silverado 1500s, the ACDelco Gold 94RAGM is the best battery to buy because it matches the GM specification. If your truck is built around a Group 48, choose the ACDelco 48AGM.
For a 3.0L Duramax, the ACDelco 49AGM is the fit, and older trucks with side terminals are best served by the OPTIMA RedTop 34/78. Whatever you choose, confirm the group on your current battery first.
