Battery Safety:
Never leave batteries or devices unattended while charging and once the battery is fully charged, disconnect it from the charger. Li-Ion batteries if faulty can catch fire.
Store batteries safely and do not allow metal objects like other battery terminals, screws, keys etc to come in contact with the terminals as this can cause the battery to short and cause a fire.
