There is a warning that it should be used in a well ventilated area, and not installed in an airtight container. Does this battery outgas toxic fumes?

These are sealed batteries. That is a standard warning on all lead acid batteries. The chance of gas being released is very small. They are used on thousands of Jazzy motorized wheelchair scooters.

If it is airtight and charging, it will probably blow up, seen it happen before, moved an entire wall. The challenge with sealed batteries is they are not really sealed, they have an exhaust port. Mostly what they give off is hydrogen and oxygen when charging and discharging and they then regenerate these gasses when charging. Charging too hot and fast means your gasses leave the battery and don't come back, so there is less charge. My nonprofit, MobilityMedicalProject.org is now an MK dealer, and I recommend them much more, plus they are guaranteed to be fresh and not new and sat on a shelf for 6 years.

It was used in my brothers electric cart (like a Jazzy). The batteries were enclosed but it was by no means airtight. I never measured it with instrumentation but we suffered no ill effects while they were used in the house. So it didn't but it might. Sorry I don't have a better answer.

The key here is "airtight container". My family has used these gel-filled batteries in handicap scooters since the mid- "90's , including on commercial flights, with NO problems whatsoever. (commercial flights mandate these batteries. Regular electrolyte batteries (automotive type) are not approved for transport in handicap scooters or powered wheel chairs on commercial flights).Thousands, probably hundreds of thousands are used daily worldwide and I have never heard of a problem. Under what circumstances would you want to put them in an airtight container?

I'll add to the other responses. NO! Li-Ion batteries have a high explosion danger when you do that kind of thing.

Khang,I would not let in run in an occupied room overnight, because ozone is quite toxic. The device generates enough ozone to smell, which I would consider too much to breath for extended periods.

I wouldn't use it indoors. Even with good ventilation the charcoal smells and eats up the oxygen in the room. Better be safe than sorry and keep it outside where it was meant to be.

I don't know exactly how low they will tolerate but I've had mine out in minus -20 degree temps without any problem, its best to use the external 6 volt lead acid battery in its weatherproof enclosure, I also cover the battery case with a plastic bag, this is what I do, I live in upstate central NY , Good Luck and if I can be any more help, just ask Sincerely Mary

Not recommended as you would be able to smell fumes. Garage works great as it is somewhat vented

Probably not.......they emit carbon monoxide which can be fatal. I use it in a ventilated garage for short periods of time.

I had the same question. My solution is to keep it in the closet in the house until we are ready to go out. I do the same with any liquid item, batteries, etc., that the AZ heat is likely to destroy.

I have charged mine indoors no problem. Good rule of thumb is to always have ventilation, but you should be fine. Very contained battery. I have two, and I have been really pleased with them.

It is not recommended for indoor use but if must, make sure the area is well ventilated

I definitely wouldn't consider using this outside because it's not sealed against water damage, and in high temperature could cause the batteries inside to explode.

It depends on how much ventilation there is. This heater is designed not to produce carbon monoxide, but it does consume oxygen, and produce carbon dioxide, which is also toxic! So if you do use this in an enclosed space, such as a tent, there had better be plenty of airflow, otherwise you will suffocate.

I live in a very cold place, this type (lipo) of battery heats up when in use, but leave out in cold without using will probably ruin them.

I'm not sure. I use it in a gun safe which is airtight. I would call the manufacturer to get a correct response.

I keep it plugged in at all times. I am assuming it is safe, because there were no warnings against using while in the car. You use purifiers such as this in the home while people are in there. It is for allergy's also to purify the air. If unsure ask the company!

I never used mine because the rubber compound in the cover releases an overwhelming toxic smell! It's still in my garage airing out ! Maybe in a few months it will de-gas

I am using in hobby greenhouse with high humidity. Don't see why vent a crawl space would be a problem
