SOmeone asked about the shelflife of the FRH (Flameless Ration Heater a.k.a. ‘NRE heater’). The must-bookmark website, www.mreinfo.com , says five years. I just tried out one of my ten year old FRH’s. I think there was some decreased performance but not enough to be a concern…I would say that ten years is about the limit.

many years
will stay fresh in sealed pouch. keep them in a above zero storage away from heat and sunlight.
