Lithium & E-Bike Battery Charging
Spot it
Batteries charging overnight unattended, off-brand chargers, batteries that are swollen, dropped, or hot, charging stations blocking the door you'd escape through.
Fix it
Charge on a hard, non-combustible surface, away from exits, while someone's awake and home. Use only the manufacturer's charger, and buy UL-listed (UL 2849 e-bike systems / UL 2271 batteries). Retire damaged or swollen batteries via battery recycling — never the trash.
Safer swaps
What actually fixes this — the category to look for, not a brand we were paid to name.
UL 2849-certified e-bike / charger system
Certification is the buy-signal for this class
Smart plug with charge timer
Ends the overnight-charge habit
No shopping list for this hazard — the fix is a habit, not a purchase.
