Battery Discharge, Defect Evidence and Warranty Routing
- Distinguish discharge from a documented battery defect.
- Preserve test evidence, purchase records and battery identification.
- Route claims using verified category, usage and supplier terms.
- Battery charger — Recharge using equipment and settings approved for the installed battery.
- Battery tester — Perform the battery-approved test and retain its test-result receipt.
- Digital multimeter — Check polarity and electrical condition as directed by the battery service instructions; do not treat a voltage reading alone as defect evidence.
- Inspection light — Inspect the case, terminals, installation, date label and factory code.
- Camera — Record battery identification, date markings, visible condition and purchase evidence for the claim file.
CBS_Battery_Warranty_2024_MAR_1_.pdf is a warranty document, not a charging or battery-capacity service manual. The Continental policy on page 2 is labeled updated November 2023 despite the filename. Match brand, battery category, usage and proof of purchase before evaluating coverage, and confirm the current policy with the supplier.
Page 2 requires charging and testing before claim submission. Page 4 instructs the owner to test first, retain the test-result receipt and recharge and retest a merely discharged battery. Discharge alone is not a covered defect. Use the battery’s own approved charging and test method; this document supplies no universal charging voltage, load-test current or terminal torque.
Free replacement applies to the original purchaser with original proof of purchase. The marked Continental date label is used for determination; if it is unmarked, page 2 says the factory date code is used. Page 4 calculates the applicable limited-warranty period from the sale to the original purchaser, so preserve both records and ask the supplier to resolve any missing-date discrepancy.
The Continental table lists 12 months for marine deep-cycle 12 V and 18 months for marine AGM; its SLA category lists 6 months, while SLA Heavy Duty is 12 months. These are distinct classifications. Page 2 states that batteries used in commercial applications are limited to half the warranty period; do not silently apply that rule to the separate partner-brand tables.
Neglect, misapplication, damaged or tampered date codes, improper installation, reverse polarity, overcharging and improper storage are among the exclusions. Describe test evidence and observed condition rather than promising coverage. Return a still-defective, in-period battery through an authorized CBS retailer; replacement is subject to installation charges, taxes and government fees as stated on page 4.
How It Works
Discharge is a condition, not a defect verdict
A discharged battery lacks available stored energy, but that condition alone does not establish an internal defect or qualify for coverage. Recharge and retest a merely discharged battery using its approved method, retaining the test-result receipt. The warranty document supplies no universal charging voltage, load-test current or terminal torque.
Coverage depends on correct classification
Match the brand, battery category and actual usage before selecting a warranty period: Continental marine deep-cycle 12 V lists 12 months, marine AGM lists 18 months, SLA lists 6 months and SLA Heavy Duty lists 12 months. Continental commercial applications are limited to half the applicable warranty period; do not extend that rule to separate partner-brand tables. Confirm current terms with the supplier because the Continental policy is labeled updated November 2023 despite the filename.
Build an evidence file, not a coverage promise
Free replacement applies to the original purchaser with original proof of purchase; preserve the marked Continental date label and factory code because the policy uses the factory code when the label is unmarked. Also preserve the sale record because the owner instructions calculate the applicable limited-warranty period from sale to the original purchaser, and ask the supplier to resolve missing-date discrepancies. Document possible exclusions and route a still-defective, in-period battery through an authorized CBS retailer, explaining that installation charges, taxes and government fees may apply.

Diagnostic Chart
| Symptom | Check | Spec / Expected | Likely cause & fix |
|---|---|---|---|
| Battery is discharged and the owner requests replacement. | Identify the installed battery and approved service method, recharge and retest, and retain the test-result receipt. | Discharge alone is not a covered defect; charging and testing are required before claim submission. | Low state of charge may explain the complaint without establishing a warrantable defect. Basis: CBS_Battery_Warranty_2024_MAR_1_.pdf |
| Battery remains defective after approved charging and testing. | Preserve test evidence, inspect for possible exclusions, and verify purchaser eligibility, coverage period and current supplier terms. | Return a still-defective, in-period battery through an authorized CBS retailer; replacement is subject to installation charges, taxes and government fees. | A documented defect may support claim review, but test failure alone does not establish coverage. Basis: CBS_Battery_Warranty_2024_MAR_1_.pdf |
| Coverage is uncertain because the date label is unmarked or records disagree. | Preserve the date label, factory code and original proof of purchase; ask the supplier to resolve the discrepancy. | The factory date code is used when the Continental date label is unmarked; owner instructions calculate the applicable limited-warranty period from sale to the original purchaser. | Missing or inconsistent date evidence prevents confident coverage determination. Basis: CBS_Battery_Warranty_2024_MAR_1_.pdf |
| Claim preparation reveals installation damage or questionable use. | Document observed condition, polarity, application, storage history and date-code condition without assuming acceptance or rejection. | Exclusions include neglect, misapplication, damaged or tampered date codes, improper installation, reverse polarity, overcharging and improper storage. | The complaint may involve an excluded condition rather than a covered defect.

Common Bay Mistakes
- ✕ Calling discharge a covered defect without recharge and retest evidence.
- ✕ Using warranty periods as charging or testing instructions.
- ✕ Combining SLA with SLA Heavy Duty or extending Continental rules to partner brands.
- ✕ Promising a cost-free replacement before supplier review.

Hands-on: Test Bench Practice
Symptom: Healthy trailer. Learn what good readings look like.
Tap a point to place the red probe.
Good system: ~12.6 V at pins, 3.2 Ω across a 12×2-inch magnet (unplugged), 3.0 A per magnet at 12 V full gain, and at least 10.5 V at the magnet — the chart values from the axle manuals.
Hands-on: Shop Test Equipment
Breakaway Switch & Battery Load Tester
Voltmeter at the battery, clamp meter on the brake feed, pull-pin lanyard
🛠 Equip your bay for this test →Symptom: Annual DOT inspection.
Spec limits used
- ≥ 15 minutes — Brakes applied after breakaway (49 CFR 393.43)
- 2 minutes — Max time with pin pulled during testing (Dexter)
- 3.0 A each — Magnet current (warm) (Dexter magnet data (simulator basis))
- illustrative only — Loaded-voltage pass threshold (General shop practice)
Simulated readings for practice. Always follow the manufacturer's procedure and values on a real trailer.
