Choose and charge with evidence
The guidance recommends choosing products certified by a nationally recognized testing laboratory. It also advises following the manufacturer’s instructions rather than mixing unverified batteries, chargers or modifications.
Keep charging visible
ULSE advises against charging under pillows, blankets or inside bags and recommends keeping devices away from extreme temperatures and flammable materials. Users should watch for swelling, punctures, unusual sounds, excess heat, odor or smoke.
Disposal is part of safety
