Battery End-of-Life Handoff
The end-of-life handoff is the transfer of custody when a battery leaves controlled operations for a recycler, treatment facility or other downstream partner. It happens when batteries are returned by customers or field service, removed from vehicles, equipment or stationary storage, declared unfit for reuse, or classified as damaged, defective or recalled (DDR).
Failures at this point include:
- No documented waste determination before the battery moves (see Battery Waste Classification).
- Gaps in chain-of-custody records between intake, transport and treatment.
- DDR batteries shipped under normal packaging and declarations.
- A downstream partner without the permits, scope or records to prove treatment.
Six-step handoff workflow
| Step | What to do | Output |
|---|---|---|
| 1. Intake | Capture unit identity, configuration and condition | Intake record with serial capture and condition classification |
| 2. Determination | Make the waste determination and jurisdiction-specific classification | Waste determination record and routing decision |
| 3. Hazard controls | Segregate, store safely and escalate DDR batteries | Storage assignment and hazard control checklist |
| 4. Shipment file | Prepare packaging, marking, labels, transport documents and carrier acceptance | Shipment file tied to the batch or unit |
| 5. Custody transfer | Obtain documented acceptance from the downstream partner | Chain-of-custody record with signatures and dates |
| 6. Treatment evidence | Collect treatment evidence and reconcile it against what was shipped | Certificates, treatment reports, reconciliation register |
Packaging and transport rules for waste and DDR batteries are on Battery Transport & Storage Controls.
Information that travels with the battery
Send the downstream partner what it needs to handle the battery safely, and retain the full record internally as audit evidence.
| Information | What it is | Used for |
|---|---|---|
| Identity and type | Battery type, chemistry, configuration, unit ID where available | Safe handling, sorting and routing |
| Condition and risk | Normal, suspect or DDR; known events; physical damage indicators | Packaging choice, storage segregation, treatment approach |
| Handling guidance | Isolation steps, connector protection, thermal precautions | Preventing incidents during loading, storage and disassembly |
| Transport classification | Declared classification, packaging instruction, labels and documents | Lawful transport and carrier acceptance |
Downstream partner checks (permits and scope, DDR capability, evidence production) are covered on How to Qualify a Battery Recycler. The records to retain after the handoff are listed on Battery Reporting & Recordkeeping.
