If used inside an insulated foam container, how long will these continue to operate near peak value?

They're the best ice packs I've ever used. Because they're small, it's easy to pack them strategically in order to keep food/drinks cold. I ordered a box of 48, and only use half in a large chest. You won't be disappointed.

At lot depends upon how they are used. Individually, they are no more or less effective than ice itself, but without the mess. When taken as a group of packets inside a gallon storage bag, they tend to help keep each other cold and thus, last a lot longer than ice (which melts and makes a mess). Effectively, they'll keep a ice chest cold for several days without taking them out and refreezing them. I haven't actually timed their duration, but the are subject to the same kind of thing that causes ice to melt. The colder the container, the longer they last, keeping the container cold. I haven't found foam containers to be that effective as "ice chests" because the foam is more insulation, than anything to prevent cold or heat from seeping through. You need the "wall" of plastic (or whatever) on both sides of the foam to be the most effective when using an container to keep something warm or cold.

I wouldn't know specifics but I've put one in my insulated lunch bag and it lasts many hours. One day it was still frozen when I came home (9 hours later) . I normally don't use them for that, I use them for a shoulder sling with an ice pack slot.

Probably, one year max at room temp. I bought six, I put 4 in the freezer, two in the refrig, I'm already on my second box, they are so good!

I read somewhere that these are suppose to last for up to a year. Just make sure you keep them stored somewhere cool.

No you cannot anything for a very long time in this container because it is not insulated.

I have 2 and stick one in the fridge when not in use. Doing it that way keeps them going for about an hour

Can be stored indefinitely as long as they are not punctured and use depends on a lot of things...elevation valve setting (wide open or throttled) but frugal use I have got around 7 hours of cool time

I have many of these in service and I find they last 5 mos max, instructions say every 6 though.

I think they will last that long with no problems. I keep mine in a sealed bag and soak in a weak fertilizer solution before I use.

So long as it is in the fridge, the bubbles will last for a lot longer. Obviously, the colder the better, but if you have a decently cold fridge, you should have a couple of weeks, at least. I usually charge it, tilt it side to side for a bit, then put it in the fridge. I tilt or shake it just before use, as well. I use a little at a time, and it always seems to have fizz.

Depends on the temperature of where they are stored. A stable 50-60 degrees should give 10 years at least. Wild temp flux or higher storage temp can reduce it down to 3 or 4.

No more than a couple of hours, but your freezer may vary. I keep mine kind of cold, but I store these on the freezer door, so that has a tendency to affect things on my end.

I have had them unopened for up to 2years and has not gone bad. I store them indoors and not in the garage until ready to use.

I will handle that for about 5 to 8 hours and not more than that on two batteries. I have a koolatron cooler hooked to mine and it last about 8 hours

This product doesn't have a shelf life that I'm aware of. The contents are under pressure. As long as the integrity of the container isn't compromised you should be good to go.

Hard to say, depends on when you buy them. I'd ask the company how long they keep for, but I don't think you'll have a problem with them sitting around going bad. They're too addictive.

I've only had this case for about four months and I have not seen any failure in the foam. This is one of the cases with pluck and use foam which means that the two pieces are basically cut into 1/2" cubes the depth of the foam with about a 1" or so solid boarder. To use the case you pull out the cubes till you have the size hole you need. I have notices that on those compartments which I use a lot some of the cubes are curling in and will eventually fall out. If that is the failure then yes I've experienced that. I live in Hawaii and here the life expectancy of any synthetic rubber or foam is limited. I have five cases for scientific equipment where I work at the university. They have a similar foam padding inside and are over ten years old. I have noticed that some of the foam is getting sticky and needs to be wiped off the equipment before use. I expect to have to replace the foam in this case at some point. I am using the case to store DSLR cameras and lenses and I purchased cloth bags to use to keep foam dust from collecting on these components. Based on my experience above I will be watching the foam for deterioration. One could replace it right away but I think that you should expect a couple of years of usage from the supplied material. It all depends on the individual.

I have kept them at regular room temperature for as long as 3 and 4 months and they seem to be absolutely fine. Never kept it longer than 4 months, so I wouldn't know beyond that.
