To extend the life of your Lost Mary Nera 30K, use the device within its recommended settings and recharge the battery before it becomes completely drained. Store it in a cool, dry place away from direct sunlight and extreme temperatures to protect both the battery and e-liquid quality. Avoid taking long, continuous puffs, as this can overheat the coil and reduce flavour consistency. Keeping the mouthpiece clean and handling the device carefully will also help maintain smooth performance. With proper care and regular charging, you can enjoy consistent flavour, longer battery life, and maximize the full puff capacity of your Lost Mary Nera 30K.
