The US Consumer Product Safety Commission warns that chargers marketed as universal may be incompatible with an e-bike or scooter battery and cause fires. A connector that physically fits is not proof of compatibility. Follow the device manufacturer's guidance.

Confirm the exact device, battery and charger model; use the supplied or manufacturer-approved charger.
If replacing a charger, ask the manufacturer for a tested compatible model instead of relying on a 'universal' label.
Stop charging and using a swollen, damaged or unusually hot battery; follow safety instructions and seek professional help.
Charge only while an awake person can supervise, never leave charging unattended while sleeping.
Follow the charging instructions and unplug when the charging cycle is complete.
Do not modify or rebuild cells through unqualified repairs; take used lithium batteries to appropriate local collection, not household trash or mixed recycling.
