(1) Does this ever expire or lose pressure? (2) How long can it be kept? And (3) can it be kept in a vehicle, or will that make it not dependable?

Yes, it expires eventually, I bought mine early this year & will expire on 2017. You may keep it in the vehicle but if you have harsh winter like us better keep it inside. Hope this helps.

I bought mine in August, I believe, and it came with an expiration date of August 2017. The can states "do not store above 120 F or below 32 F".

Can has expiration date on it, can should be good for five years. I kept mine in the vehicle when i traveled. Can states do not store above 120 degrees.

Honestly, I do not know. We never had an occasion to actually use the bear spray, even though we did hike upon a bear. We donated our spray to the park rangers upon leaving the park, so they could give to others. Sorry I cannot help you.

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

ive had mine for a few months now. i just used it again about a week ago and it worked just fine. bit i keep mine stored the same way the bottles came with that little plastic cap then the regular cap over and tighten it a bit. i think the key is making sure the cap is on tight so no air can ruin the liquid.

As a single data point, I kept one of these in the back of my car for 14 years living in the Mojave Desert (temperatures regularly over 110). When I saw a car on fire on the side of the highway earlier this year, the fire extinguisher performed flawlessly, except for one problem: When I tried to pull the pin, the plastic ring snapped off. I suspect the plastic had gotten brittle sitting in the back of my car for 14 years. I was able to get the pin out and put out the fire though. I would suggest checking the pressure regularly by pressing the little green button on the extinguisher, and also replacing it before 14 years (I think it is recommended to replace them every 10 years).

The can contains inert gases. They won't wear out, though the can may eventually leak. I venture that would take a *long* time. This is an *excellent* product. It's much better than using a vacuum pump, for example.

If you mean Shelf life. A Long time at least 5 yrs possibly 10 but in use It all depends on the load of device they are used in Mine was in the remote for our Lexus and it lasted little over 2-1/2 years so if it has been in use in a device you might want to get a spare ! Keep new batteries in refer. Until needed they last longer when kept cold . And the 2011 is the copyright date not the manufacture date you are right no use by date !

It will last indefinitely. As long as you don't let the can rust or anything like that. Keep it I stored at a stable temperature and stable humidity (in the house as an example.) and it will be fine.

I've had mine for almost 1year now, and it's still pretty good. Keeping it in an air tight container helps it to last long.

It has been packed with an oxygen absorber so it should have at least a five year shelf life if unopened. After opening it should have 9 months to a year.

I try to keep some on hand continuously, just in case I might need it. I carry one gallon pre-mixed 50/50 in my Audi, and keep one gallon in my garage.

You can keep it in your car, but realize that cold temps will make it much weaker if and when needed. Keeping it charged is the biggest factor in making it last, so keep that up if you want it to have a chance at working.

I leave a pump or two in all the time, it holds between use at this low pressure so far. I have left 1 pump in for as long as 6 months so that is as long as I can advise on low pressures. I have left it pumped to full power for about a week with no loss of power but not any longer than a week. The condition of the seals and such may also factor in at any pressure.

That's a good question. I currently have 2 from last year that still work fine. I expect to use them up this season, but going out on a limb, I'd say there is no reason why a can wouldn't be good for quite a few years. Even spray paint lasts years.

I had it for a couple of years and it appears to be holding up OK (no obvious links, failure of seals or cap, brittleness of materials). I only drag it with me when I need the volume so it's getting used 3-4 times a year. It's currently on loan to a trusted buddy. I am fairly careful with it because it's made of materials that could puncture it so I don't pack it next to a spork or put it on the outside of my pack in a spot where a branch could poke it.

I also keep some in my car, I live in Florida. They will not contaminate unless they are punctures or the seal is broken. However, if you keep the water in their or in changing temperature environments for over 4-5 years the water will go flat and somewhat stale. However still safe to drink.

The first question I would ask is: is it open? Where did you store it? If you had not opened it and it was stored in a cool dry place, I it would be fine. If not you should dispose of it. In the grand scheme of things this stuff costs $7. If in doubt throw it out. I only bought it because it extends my warranty. I like that it's 95 octane. I usually mix my own at 40:1 or 50:1.

Is it ok to store in the vehicle? I read the manual and it says never to let it freeze and store at room temperature.
