It is shown that thermal runaway can occur from self-discharge of sealed Ni-Cd batteries at elevated temperatures. The process can be fast enough to rupture cells in batteries and cause physical damage to surrounding areas. Therefore the temperature of a charged battery must be limited for safety reasons even on open circuit. The temperature limit will depend on the particular thermal environment.
