A battery and cooling device system comprising a thermal battery and a cooling device including a boiler, a condenser, a vapor tube, a reaction container, and a siphon. The boiler boils a solvent via heat drawn from the battery. The condenser condenses the vaporized solvent. The vapor tube connects the boiler to the reaction container so that the vaporized solvent travels through the vapor tube from the boiler into the condenser. The reaction container receives the liquidated solvent from the condenser so that the liquidated solvent interacts with a solute in the reaction container to effect an endothermic reaction to further draw heat from the battery. The siphon connects the reaction container to the boiler and drains the liquid solvent from the reaction container into the boiler once a predetermined amount of liquid solvent fills the reaction container.
