1. Scope and Applicability
This PCR applies to new primary cells and primary batteries that deliver electrical energy by direct conversion of chemical energy and are not designed to be electrically recharged. It covers a single cell and a group of primary cells connected or enclosed as a complete battery, in the condition in which the product leaves the manufacturing site. The foreground boundary covers received material preparation, component forming, electrode and electrolyte preparation, cell assembly and filling, sealing, inspection, electrical testing, marking, and packaging.
The category includes zinc-manganese dioxide, alkaline manganese dioxide-zinc, primary lithium, zinc-air, silver-oxide, and other non-rechargeable electrochemical systems when the dataset declares the actual chemistry and provides a complete route-specific atomic inventory. The representative route in this PCR is a cylindrical alkaline manganese dioxide-zinc battery. The representative inventory is not a substitute for the bill of materials of another chemistry or format.
Rechargeable accumulators, rechargeable battery packs, capacitors, battery parts sold separately, spent batteries, recycling, charging, use, and end-of-life treatment are excluded. A product marketed for recharging is outside this PCR even if it can also be used once.

3. Reference Flow
| Field | Value |
|---|---|
| What | Delivery of electrical energy by a declared primary electrochemical cell or battery |
| How much | One conforming primary cell or primary battery of the declared chemistry, format, and rated capacity |
| How well | Meets the declared rated voltage and capacity under the stated discharge load, duty cycle, temperature, and end-point voltage, and meets the declared leakage and safety acceptance criteria |

When constructing a foreground data package, the items listed in Required qualifiers must be declared in dataset metadata, process notes, reference flow comment, product description, or an equivalent data package field. Missing required qualifiers make the reference flow definition incomplete for that data package. A non-alkaline product may use this PCR only after replacing the representative product flow with an exact route-specific flow and providing its complete route-specific inventory.

Elementary flows
No default direct emission is prescribed. Add each measured or permitted direct emission as one species- and compartment-specific elementary-flow output; do not report an umbrella emissions row.
7. Allocation and Co-product Handling
| rule_id | Applies to | Rule | source_ids |
|---|---|---|---|
allocation_direct_assignment | Multiple products or production lines | Prefer subdivision, dedicated meters, batch records, equipment time, and material issue records so inputs and wastes are directly assigned to the declared primary-battery product. | |
allocation_joint_outputs | Inseparable saleable co-products | Do not apply an undocumented default factor. Declare the co-product, causal relationship, allocation property, prices or physical quantities, allocation period, and sensitivity result; unresolved joint production requires methodology review before publication. | |
allocation_recycling | Internal recycle and external recovery | Count internal recycle once and subtract only documented returns from gross issues. Do not credit avoided primary production or future recycling inside the factory-gate foreground result; report any such credit as a separate disclosed scenario. |

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
|---|---|---|---|---|---|
calc_per_item_inventory | Every inventory exchange | Divide the exchange quantity assigned to the production period by the number of conforming sale-ready reference items from the same period. | Net exchange quantity; conforming output items | Exchange per reference item | |
calc_solution_reporting | Potassium-hydroxide solution and waste alkaline liquor | Report as-delivered solution mass and concentration.

System boundary rules · 4
| Rule ID | Applies to | Rule | Source IDs |
|---|---|---|---|
sb_factory_gate | Foreground manufacture | Include material forming, active-material and electrolyte preparation performed on site, cell assembly and filling, sealing, inspection, electrical testing, marking, and packaging through the sale-ready factory gate. | us-epa-primary-battery-manufacturing-1975, energizer-alkaline-handbook-2018 |
sb_upstream_inputs | Purchased inputs | Link upstream production and delivery datasets for every purchased input; keep the foreground amount as the actual net site receipt or consumption. | |
sb_downstream_exclusion | Downstream stages | Exclude distribution after the factory gate, use, attempted recharging, and end-of-life treatment unless a separate study system explicitly adds those stages. | eu-batteries-regulation-2023 |
sb_route_completeness | Non-representative chemistry or format | Replace the representative alkaline bill of materials with the actual atomic exchanges and disclose all route-specific active materials, electrolyte, container, terminals, separator, seals, labels, process emissions, and wastes. | eu-batteries-regulation-2023, energizer-alkaline-ais-2022 |
Allocation rules · 3
| Rule ID | Applies to | Rule | Source IDs |
|---|---|---|---|
allocation_direct_assignment | Multiple products or production lines | Prefer subdivision, dedicated meters, batch records, equipment time, and material issue records so inputs and wastes are directly assigned to the declared primary-battery product. | |
allocation_joint_outputs | Inseparable saleable co-products | Do not apply an undocumented default factor. Declare the co-product, causal relationship, allocation property, prices or physical quantities, allocation period, and sensitivity result; unresolved joint production requires methodology review before publication. | |
allocation_recycling | Internal recycle and external recovery | Count internal recycle once and subtract only documented returns from gross issues. Do not credit avoided primary production or future recycling inside the factory-gate foreground result; report any such credit as a separate disclosed scenario. |
