Lithium-ion batteries may swell from a deep discharge in the cells; typically, Lithium-ion batteries are controlled by a circuitry, sometimes called the Battery Management System, or BMS, which keeps this from happening. Lithium-ion batteries have a very long cycle and storage time, meaning that they can be charged and discharged many hundreds of times before losing effectiveness.
In cold temperatures, batteries work well, but cannot be charged quickly without incurring serious damage. Lithium-ion batteries have low self-discharge rates, meaning that a charged battery can be left sitting around for some time between uses without losing a lot of energy. Because of this, any device using a lithium-ion battery needs to incorporate circuitry that can detect these runaway cycles and turn off the battery.
As lithium-ion batteries age, the chemical reactions that generate electricity are no longer completely completed, creating gases that can make a battery bulge.
