To check an ACDelco battery’s warranty date, use the warranty date code stamped on the case and match it to the ACDelco battery warranty date code chart.
Have you ever tried to make a warranty claim on your battery, only to be told it’s expired—despite barely remembering when you installed it? That’s because battery warranties don’t rely on when you bought it, but rather when it was manufactured. ACDelco encodes this crucial information using a specific date code stamped onto the battery itself, typically a combination of letters and numbers.
Understanding this code is essential for verifying if your battery is still under warranty. Whether you’re a DIY car owner, fleet manager, or professional mechanic, being able to quickly decode this info can save time, money, and headaches.

How to Read an ACDelco Warranty Date Code [with Chart]
Understanding how to read an ACDelco battery warranty date code is essential for determining whether your battery is still under manufacturer warranty. This alphanumeric code is usually stamped on the top or side of the battery casing.
What the Code Looks Like
The warranty date code generally consists of one letter followed by a number, such as C3 or H9. Here’s what each character represents:
- Letter = Month
A = January, B = February, C = March… L = December - Number = Year
3 = 2023, 4 = 2024, 5 = 2025, and so on
For example, a code like C3 means the battery was manufactured in March 2023.
ACDelco Warranty Date Code Chart
| Code | Month | Year |
| A3 | January | 2023 |
| B3 | February | 2023 |
| C3 | March | 2023 |
| D3 | April | 2023 |
| … | … | … |
| L3 | December | 2023 |
| A4 | January | 2024 |
| B4 | February | 2024 |
| … | … | … |
Where to Find the Code
Look for a heat-stamped or printed code:
- On the top casing near the terminal
- On the side wall of the battery
- Or on the label (if present)
If the code is faded or unclear, use a flashlight and magnifier to make it more visible. Once identified, compare it to the chart to determine warranty eligibility.
How ACDelco Battery Warranties Work
Knowing how ACDelco battery warranties work can help you avoid unexpected costs and denied claims. It’s not just about how long ago you bought the battery—it’s about when it was manufactured and installed.
Warranty Types and Coverage Periods
ACDelco offers different types of batteries, each with its own warranty terms. Here’s a general breakdown:
- ACDelco Gold (Professional) Batteries:
Typically come with a 42-month free replacement limited warranty. - ACDelco Silver (Advantage) Batteries:
Often include an 18-month limited warranty. - ACDelco Gold AGM (Absorbed Glass Mat) Batteries:
Provide up to 36–48 months of warranty depending on the model.
These warranties cover manufacturer defects, not wear and tear or improper use.
Warranty Claim Requirements
To file a claim, most retailers or dealers will ask for:
- The original purchase receipt
- Battery test results confirming failure
- The date code to verify manufacturing date
That’s why decoding the warranty date is crucial—if your battery was manufactured 3+ years ago, it may no longer be eligible for replacement, even if you installed it recently.
Important Notes
- Warranties start from the manufacture date, not the install date, unless registered.
- Improper installation, misuse, or vehicle issues can void the warranty.
- Keep records of purchase and installation for smoother claims.
Tips for Making a Successful ACDelco Battery Warranty Claim
Filing a battery warranty claim can be smooth—or frustrating—depending on how well-prepared you are. With ACDelco, following the proper process is key to getting a free replacement or refund if your battery fails under warranty.
Locate and Decode the Warranty Date Code
Before starting a claim, identify the alphanumeric code on your battery (e.g., C3, F4). Use the ACDelco warranty date code chart to verify that the battery is within the eligible time frame.
Pro Tip: If your battery is older than the warranty coverage (e.g., 42 months for Gold), a claim may be denied automatically.
Gather Your Documentation
Most ACDelco warranty claims require:
- Original purchase receipt or invoice
- Battery test results from an auto parts store or technician
- Vehicle mileage at the time of battery installation and failure
Without proof of purchase, even a valid date code may not be enough.
Test the Battery First
Before visiting the store or dealership, use a battery tester (or have it tested for free at a parts store). You’ll need results that show the battery is faulty and not just discharged.
Visit an Authorized Retailer or Service Center
Take your battery and documents to an ACDelco-authorized retailer, GM dealership, or service center. They’ll inspect the battery, verify the code, and process your claim if approved.
Don’t Modify or Tamper with the Battery
Batteries with physical damage, missing labels, or altered date codes are typically disqualified from warranty claims.
Where to Buy ACDelco Batteries with Full Warranty Support
Buying your ACDelco battery from an authorized seller is the best way to ensure your warranty is valid and easy to claim if needed. While ACDelco batteries are widely available, not every retailer offers the same level of warranty support.
Authorized ACDelco Dealers and GM Service Centers
The most reliable option is purchasing directly from:
- GM dealerships
- Certified ACDelco service centers
These locations guarantee:
- Authentic products
- Official warranty registration
- Immediate support for any future claims
Bonus: Some GM service centers may even install the battery for free with purchase.
Major Auto Parts Retailers
Trusted names like AutoZone, Advance Auto Parts, O’Reilly Auto Parts, and NAPA carry ACDelco batteries both in-store and online. Make sure to:
- Confirm they’re selling new, not refurbished batteries
- Keep your receipt and warranty paperwork
- Ask about on-site testing and installation services
These stores often test failed batteries on-site and initiate warranty claims without sending you elsewhere.
Online Marketplaces (With Caution)
Sites like Amazon and eBay may offer attractive prices, but:
- Always check seller ratings
- Ensure the battery is new and not aftermarket
- Verify that the product includes manufacturer warranty documentation
Pro Tip: Batteries sold by third-party sellers may not be covered by ACDelco’s official warranty.
Common Reasons ACDelco Battery Warranty Claims Get Denied
Understanding the common reasons ACDelco battery warranty claims get denied can save you from disappointment and wasted time. Even if your battery seems eligible, certain missteps can void your warranty.
Expired Warranty Coverage
This is the most frequent issue. ACDelco battery warranties begin from the manufacture date, not the installation date—unless properly registered. If your battery code indicates it’s older than the warranty period (e.g., 42 months for Gold), the claim will be rejected.
Solution: Always check the warranty date code using the chart and confirm you’re within the valid time frame.
No Proof of Purchase
Without an original receipt or invoice, ACDelco often cannot honor the warranty. The purchase location and date must be verifiable.
Pro Tip: Take a photo of your receipt and email it to yourself as a backup.
Battery Was Misused or Damaged
Warranty coverage does not extend to:
- Physical damage (cracked case, burned terminals)
- Overcharging or undercharging
- Improper installation or fitment
- Vehicle electrical issues (e.g., bad alternator)
Third-Party or Unauthorized Seller Purchase
Buying from non-authorized retailers or online marketplaces (like eBay or independent sellers on Amazon) often results in denied claims.
Always ask the seller if they’re authorized and if warranty paperwork is included.
Missing or Altered Battery Codes
If the manufacturing date code is scratched off, faded beyond recognition, or appears tampered with, the battery becomes ineligible for warranty replacement.
Conclusion
Decoding the ACDelco battery warranty date code is a simple but powerful step in protecting your investment. By using the alphanumeric date stamp and matching it to the ACDelco warranty chart, you can determine whether your battery is still under coverage. Understanding how the warranty process works, keeping your proof of purchase, and buying from authorized retailers can make all the difference when filing a claim.
Whether you’re maintaining a personal vehicle or managing a fleet, being proactive about your battery’s warranty ensures you avoid unnecessary replacements and denied claims. Take the time to check your battery code today—you might save yourself a trip to the auto parts store tomorrow.
