How long will these 40 gram passive dehumidifiers last without a recharge? Ballpark -- days, weeks, months, years?

There are a few varibles to consider. The size of your safe, location, how often is it opened. My own personal experience is that I recharge mine about once a month.

I get six months in sealed Space Bags. 2 weeks in a safe that's opened 2-3 times per week. This is in Houston. Your mileage may vary.

I would say a few weeks, depending where you put them. If you have them in a rather air-tight container, they last a very long time...if there is air exchange, they obviously won't last as long. I like them a lot but I did have one go bad on me...when I was re-charging...for some odd reason, the balls turned black...rendering that one useless...the others that were in the same condition and were heated for the same time did just fine...

I guess it depends on 'how humid your storage area is?' I try to minimize it by placing my valued items in freezer bags or air tight boxes in my safe. This definitely extends to time between recharges. Also, the more humidity the more you need to recharge it. The best part is that you can see when it needs recharging.

Mine lasts around 3 months. I think this has a lot to do with me living in the desert and the humidity level being very low (less than 15% most of the year).

There's really no accurate answer to that question without going through a big engineering process. The desiccant will hold a certain amount of water, but life in weeks or months varies based on the water content of your air, flow rate, and how much moisture you can tolerate before discarding the cartridge. We find that the desiccant bags last well. We've purchased 30-40 of these and include them in our manufactured products.

As other respondents have noted, Without getting too technical rechargeable batteries have a unspecified amount of parasitic loss depending on battery chemistry type and overall capacity.In this case the extremely large capacity of this battery will allow it store a sizable amount of energy even after a period as long as 6 months. Keep in mind that batteries like a room temperature 74 degrees Fahrenheit plus or minus a few degrees . So try and keep them in a nice cool area with plenty of fresh moving air and a very low humidity

They don't have any materials designed for cooling,not that I know what that might be. They are silicone covered with a poly material. Should last for a good long while for you but couldn't possibly be more specific. I'd assume months.

I beleive the storage is up to 90 days (or up to a year with reduces charge) , however, please note, it is best to store these in a safe indoor environment, as extreme heat or Cold can damage, and or reduce battery life span and capacity. Thank you, BuysPro

It takes several days to collect a cup of water, even in a damp room, so I would use a more powerful dehumidifier--maybe even a less energy-efficient, noisier compressor-style dehumidifier. If I use my compressor-style dehumidifier in the same room, it will remove a gallon of water in 24 hours!

I saw the other reply, which is consistent with what I remember. The dehumidifier lasted me for most of two seasons, after which the compressor ceased to produce any results, although it ran. It probably leaked all the refrigerant, and there is no practical way to recharge it. From what I have read, 2 years, sadly, is about all one can expect from these devices. By the way, I am trying a Frigidaire this time; I bought it four and half months ago, and it is still working; only time will tell if it has any more endurance than the Sunpentown; the features are nearly identical.

Probably a month or longer. I've had them out for 6 weeks and they were working.Excellent solution. I keep the unopened ones in the freezer to keep them fresher.We use two in the pantry, rotate one each two weeks, so there is a fresh one onone shelf, while the other is two weeks or older.

I try not to leave them too long after they are done charging, but the times I have (a couple of days)there wasn't a problem. I wouldn't leave them in for weeks, though. I have read somewhere there is a very slight drain over time.

I use only the drymistat just like Linda. But I use only distilled water in mine. Its only 89 cents a gallon were I live and lasts a long time. They do very well and last 2 to 3 weeks between recharges. One may not be enough. Use 1 for every 20 cigars or so. If you have the money, invest in a cigar oasis. They can't be beat.

Another reason not to use rechargeables is that they can drain while idle more quickly than alkaline batteries. I wouldn't use them if you will be gone more than a couple of days.

It depends on the battery. A Duracell cost more but will go from 3-5 days. I usually run mine all day at work. The rechargeable Tenley last a day to a day and a half. Over the long haul, they are more economical.

I don't think it would be an issue if they provided the same power as a disposable. I've only used disposable, however, mainly because the batteries last a very long time. Power usage is really minimal and my batteries are still functioning at the end of my growing season. I've replaced them each year just because I don't want to have them run out when I am not around. I water between May and October, so that may be the reason they last so long, as well.

They last quite a long time. I have had mine for over a year now. But it also depends upon how frequently and for how long of a duration you use it for. I only use mine on rainy / grey days and for 2-3 hours at a time.

I don't see why not -- you might need to recharge the unit more often. I have a very damp bathroom (and cold in the winter) and I have to charge my unit about every 15-20 days. I don't have near as big a problem with damp, though, so it's worth it.

I would say either works. Most recharge stations have a mechanism to not charge anymore once its fully charged. I have had mine for 5-6 months and I keep them plugged in, and I have not experienced any degradation of charge life or anything. I guess it would be your preference.

I don't know. I use them within a week of charging. Some that have set for 6 months still have a bit of charge to last at least an hour probably, but I didn't pay attention.
