These batteries will never puff and become unsafe, like lipos will that have been either neglected or simply aged over time. They can be charged from empty or nearly full without damaging the battery. Even if your battery gets low and your device cannot cycle, the battery is still within safe operating ranges and can be charged safely back to 100%.
