Trojan Battery Company typically stamps a manufacturing date code on the battery case or label, combining letters and numbers to indicate production month and year. For example, “A25” might denote January 2025. Newer models may use a four-digit code like “0125” (January 2025). Always verify via Trojan’s online validation tool or contact their support for precise decoding, as formats vary by battery series and region.

Where is the date code located on Trojan batteries?
Look for an alphanumeric stamp on the battery’s top case, terminal side, or label. Flooded lead-acid models often have it embossed near the fill caps, while AGM batteries print it on QR labels. Pro Tip: Use a flashlight to inspect recessed areas—some codes are laser-etched for durability.
Date codes are typically 3–4 characters long. Older Trojan batteries (pre-2020) might use a letter-number system: A=January, B=February, etc., followed by the last two digits of the year (e.g., C24 = March 2024). Newer models adopted a four-digit “MMYY” format—”0425″ translates to April 2025. For instance, a Trojan T-125 with “E23” on its case was manufactured in May 2023. Warning: Avoid confusing serial numbers (8–10 digits) with date codes—they don’t correlate to production dates.
How to decode non-standard Trojan date formats?
Some industrial batteries use Julian date codes (e.g., 23054 = 2023, 54th day). Others embed dates in serial numbers—the 3rd and 4th digits might indicate year (T105-24X = 2024). When uncertain, submit the code via Trojan’s warranty validation portal for automated interpretation.
Trojan’s Renewable Energy series batteries (RE models) often combine week numbers and years. “W1724″ means week 17 of 2024. Golf cart batteries like the TX-36 may use a letter-month system with shifted values—”H” could represent August instead of the standard “A=January” alignment. Practically speaking, if you find a code like “8D2” on a Trojan SCS150, contact their support team at 800-423-6569 with photos—they maintain internal decoding charts for legacy models. Pro Tip: For batteries sold in Asia-Pacific markets, add 1–2 months to the code date to account for shipping and customs delays.
| Code Type | Example | Translation |
|---|---|---|
| Letter-Number | D23 | April 2023 |
| Four-Digit | 1224 | December 2024 |
Does case color indicate Trojan battery age?
No—Trojan updates case colors for product differentiation, not age. A black case doesn’t mean older than a red one. However, logo designs changed in 2018 (simplified font) and 2022 (added “Since 1925” tagline)—these help approximate manufacturing periods when date codes are illegible.
For example, Trojan’s Reliant AGM series switched from glossy black to matte gray cases in 2021. Golf cart batteries retained green cases since 2015 but added holographic anti-counterfeit labels in 2023. Beyond aesthetics, check for QR code presence—most post-2020 models include scannable labels with encoded production data. A flooded T-105 manufactured in 2019 might lack this feature, while a 2024 model would have it. Pro Tip: Use the Trojan Battery Advisor app (iOS/Android) to scan QR codes—it reveals exact manufacture dates and warranty status.

FAQs
Most do, but heavily used or refurbished units might have worn stamps. Check under terminal grease—some codes are hidden near posts.
How accurate are third-party date decoders?
Only 70% reliable for pre-2020 models. Trojan’s internal database covers all variations—email [email protected] with clear code photos for confirmation.
