Li-ion notes: All lithium ion batteries have a risk of fire and/or explosion, handle batteries with care, ensuring not to overcharge or overdischarge, even if the battery contains a protection circuit. If battery is visibly damaged, stop use immediately and dispose of appropriately (Li-ion batteries pose a serious fire risk if thrown into household waste). If a battery is not to be used for over two weeks, store partially charged(30-40%) for maximum capacity retention.
