An assessment or evaluation may include, but is not limited to, the following criteria:

(a) Acute hazard, such as gas, fire, or electrolyte leaking;
(b) The use or misuse of the cell or battery;
(c) Signs of physical damage, such as deformation to cell or battery casing, or colours on the casing;
(d) External and internal short circuit protection, such as voltage or isolation measures;
(e) The condition of the cell or battery safety features; or
(f) Damage to any internal safety components, such as the battery management system.
