Guide for rechargeable batteries
This page covers rechargeable portable batteries in two practical cases: loose rechargeable AA/AAA cells and rechargeable batteries built into products. Both need capacity information, but built-in batteries also trigger additional rules on instructions, removability, online information, and QR-linked digital pages.
Core point:
For rechargeable portable batteries, capacity must be prepared as part of the battery label logic. mAh is the practical front-label value; Wh should also be shown where energy content matters, especially for Li-ion packs, power banks, and transport-facing product labels.

The crossed-out bin must be handled correctly on the battery, product, or packaging depending on the design and size.

Battery label data
General battery label information and capacity marking for rechargeable portable batteries become relevant under the label trigger.

QR page and removability
QR-linked digital information applies to all batteries. Removability and replaceability become central for many products with built-in portable batteries.
Loose rechargeable AA/AAA cells
Example: rechargeable NiMH AA or AAA cells sold as loose batteries or in a blister pack.

For rechargeable AA/AAA cells, capacity in mAh is the key practical marking. Wh can be added as calculated energy content: Wh = nominal voltage x Ah. If the full importer or manufacturer block does not fit, move full details to packaging or an accompanying document.
Built-in rechargeable batteries
Example: compact power bank, speaker, flashlight, shaver, toy, or small household device with a built-in rechargeable Li-ion battery.
Product / rating label example
Model: PB-LITE-01
Battery: Rechargeable Li-ion battery
Nominal voltage: 3.7V
Rated capacity: 2200mAh
Energy: 8.14Wh
Lot / Serial: PB260513A

Built-in rechargeable batteries need the normal battery label information plus product-level documentation. The battery, host product, packaging, manual, and digital QR information must be treated as one compliance package.
Capacity marking: mAh and Wh
What the EU rule says
- From the label trigger date, rechargeable portable batteries must carry capacity information.
- For AA/AAA rechargeable cells, mAh is the normal supplier-facing capacity value.
- The Regulation does not state that every rechargeable portable battery must show both mAh and Wh as a fixed double unit.
Practical ASIGO artwork rule
- For loose AA/AAA NiMH: show mAh; add Wh where space allows.
- For Li-ion packs, power banks, and built-in battery products: show both mAh and Wh.
- Formula: Wh = nominal voltage x Ah. Example: 3.7V x 2.2Ah = 8.14Wh.
This keeps the supplier artwork practical while avoiding a false statement that Wh is always explicitly required by Article 13(2) for every rechargeable portable battery.
What still belongs on packaging and documents
Packaging / manual / online information
Loose rechargeable AA/AAA
- full manufacturer and importer details if they do not fit on the cell
- model / IEC code, lot, chemistry, voltage, mAh, and optional Wh
- charging, storage, short-circuit, child-safety, and disposal warnings
- future QR target page and linked compliance information
Built-in rechargeable batteries
- full manufacturer name, address, website, and email
- full importer name, address, website, and email
- battery removal and replacement instructions where required
- safety information for use, charging, storage, and disposal
- future QR target page and linked digital product information
- later battery label data under Annex VI Part A and capacity label logic
Do not mix the two cases: loose rechargeable AA/AAA cells are a battery artwork problem; built-in rechargeable batteries are a battery plus product documentation problem.
What the manual and online page must cover
Manual / insert
- how to use and charge the product safely
- how to remove and replace the battery, where applicable
- fire, heat, short-circuit, and child-safety warnings
- disposal and separate collection instructions
Permanent online information
- battery removal and replacement instructions
- battery safety and disposal information
- future QR-linked product page structure
- later DoC and compliance references
Which EU points apply here
This section shows which articles matter for rechargeable portable batteries, including loose AA/AAA rechargeable cells and built-in rechargeable batteries.
Built-in portable batteries must be removable / replaceable
This applies to products incorporating portable batteries under the conditions of the Regulation.

Manual / online information section
Battery marking, capacity label, QR code
Rechargeable portable batteries fall under battery marking, capacity information, and future QR rules.
Where shown in this guide
Timeline, product example, packaging block
Manufacturer and importer identification
The manufacturer and importer still need to be clearly identifiable in the compliance package.
