Selected official sources checked . This is a limited reference, not a complete recall database or a safety clearance. Match the exact battery label, bike model and any serial or production limits in the original notice. A model year alone cannot clear a battery.
Hot, swollen, leaking, damaged or unusual smell?
Stop using and charging the battery. Do not test it again, open it, bypass its protection or attempt a cell repair. If there is smoke, fire, hissing or rapidly rising heat, move away, warn others and call local emergency services (911 in Canada and the U.S.). Do not carry an actively failing pack through your home or approach it to disconnect or photograph it.
Read the notice for your country and exact identifiers. Replacement packs can differ from the original bike specification. Do not assume every bike from a brand is affected, or that an unlisted bike is safe. The two U.S. warnings below are not agreed manufacturer recalls.
Santa Cruz Heckler 9 — battery recall
Notice dated 1 May 2025. Certain batteries in Heckler 9 bikes manufactured before February 2023 may overheat. Only some packs are affected. Pause use and charging pending the manufacturer’s battery identification check; follow its disconnection instructions only when safe. An affected pack qualifies for a free replacement through the recall process.
Warning dated 24 November 2025. Battery models RP-1304, RAD-S1304Y and HL-RP-S1304 can ignite, including while stored. CPSC says stop using these packs and arrange hazardous-waste disposal; do not sell or give them away. This is a battery-label warning, not a warning about every Rad battery or a promise of a refund. Check the original notice and contact the supplier for your region.
Warning dated 19 March 2026. Battery and wiring fire hazard. CPSC says stop using these models and arrange safe battery disposal through local hazardous-waste services. Do not sell or give away hazardous packs. Do not put them in retail battery boxes.
Use the original charger or the manufacturer’s explicitly approved replacement for the exact pack. Plug shape and voltage alone do not prove compatibility.
Stay awake and present while charging. Keep exits clear and keep the pack away from bedding and other materials that burn. Unplug after charging is complete.
Follow the maker’s temperature limits. Let a cold battery warm naturally to its permitted charging temperature; never heat it or charge below freezing.
Follow the maker’s storage charge and temperature guidance. Do not modify, force-charge, rebuild or bypass the battery management system.
Never use household garbage, curbside recycling or a general retail battery box for an e-bike pack. Call ahead: describe the pack, its size and condition, and whether it is recalled. A normal collection location may not accept a damaged, defective or recalled lithium battery.
Canada
Find an e-mobility collection point through Recycle Your Batteries, Canada! Select the e-mobility filter, then confirm acceptance. For damaged or recalled packs, contact your municipal waste facility for a special handling arrangement; do not place them in ordinary collection boxes. Damaged battery instructions.
Whole-bike options differ: the program describes selected-brand pickup in British Columbia and Ecocentre routes in Quebec. Confirm eligibility directly; collection is not guaranteed everywhere.
Ask the original manufacturer or importer, retailer and local council or hazardous-waste authority for a licensed e-bike battery collection route. Rules and accepted pack types vary by country. In the United Kingdom, government guidance describes manufacturer/importer take-back and local-authority options. Do not assume Canadian or U.S. programs accept a battery from another country.
Before transport
Do not mail, courier or take a damaged pack to a depot without its explicit instructions. Transport and packaging rules apply; some unsafe batteries cannot be transported normally. Transport Canada battery transport guidance. For an intact, stable pack only, follow the receiving program’s preparation instructions; protect exposed terminals as instructed. Never handle a hot, leaking or smoking pack to tape or bag it.
