Trojan battery age is determined by decoding the alphanumeric manufacturing code stamped on the battery case, typically found near terminals. Most models use a 6-8 digit code where the first number indicates the production year (e.g., “3” = 2023), followed by a letter for month (A=Jan to L=Dec), and subsequent digits showing the production day. Example: “3J15” translates to October 15, 2023. Always verify using Trojan’s official decoding chart as formats vary by battery series.

Where is the date code located on Trojan batteries?
Look for an embossed or laser-etched code on the battery case’s top ledge or near terminal posts. Trojan typically places it adjacent to the model number, using raised characters resistant to wear. For flooded lead-acid models, check between cell caps; AGM batteries often have it on the front label’s upper third.
Three key identification methods exist: 1) Direct stamping (e.g., “J23” = October 2023), 2) Sequential numbering (0223245 = 2023年第245天), and 3) Letter-month codes (A=Jan). Pro Tip: Use a flashlight angled at 45° to spot faint laser engravings. Real-world example: A T-1275 battery with code “L1524” decodes as December 15, 2024. Watch for exceptions—some industrial series use Julian dates where “23056” means the 56th day of 2023.
How to decode Trojan’s alphanumeric date stamps?
Trojan’s standard format uses 1 letter + 2-4 numbers. The letter represents the month (A=Jan to L=Dec), followed by a 1-digit year and 1-2 digit day. Example: “K34″ breaks down as November (K) 2023 (3) 4th day. Post-2020 codes often add a decade indicator—”H30” could mean August 2020 or 2030 depending on battery generation.
Decoding requires cross-referencing battery production years. For instance, Trojan’s RE series might use “2” for 2022 in “F29” (June 29, 2022), while their industrial line may show “E23-045” as May 23, 2023, 45th batch. Pro Tip: Download Trojan’s current decoding guide—their 2023 update added QR codes with encrypted manufacturing data. Remember: Some refurbished batteries overlay new dates on original cases, so verify through Trojan’s warranty portal.
| Code Type | Example | Translation |
|---|---|---|
| Standard | G173 | July 17, 2023 |
| Julian | 23045 | Feb 14, 2023 |
Why do date code formats vary across Trojan models?
Format differences stem from production facility standards and battery chemistry. Flooded batteries use simple embossed codes for durability, while AGM/gel models employ laser stamps with extra digits for batch tracking. Industrial series batteries (e.g., SIND series) often include plant codes—”D” in “D8L22” denotes Denver factory.
Trojan has updated coding three times since 2015: 1) Pre-2018: 4-digit (M112), 2) 2019-2021: Letter-Year-Month (A19D), and 3) Post-2022: QR hybrids. Pro Tip: When uncertain, call Trojan’s support line with battery model/serial number—they can cross-reference production records. Real-world example: A 2023 TXH battery showing “QR-7C3” links to March 7, 2023 via their web portal.

FAQs
Yes—refurbished units may show original and recondition dates. Authentic new batteries only display one code.
Do Trojan battery date codes expire?
No, but warranty claims require codes dated within 90 days of purchase. Always document your battery’s code at installation.
