What happens if the batteries die, will the heat not turn on?

Answer.I believe that the heat will still come on to what ever it was set at, you just won't see anything in the display?

I believe if the batteries are dead or missing, the thermostat won't work and the heater will not come on. It makes sense but I never tested it.

If the batteries are dead the thermostat will not work. However the batteries last a very long time so change them on a yearly basis if you are concerned.

Yes - You are correct. The battery will overheat and it can be damaged! Try using a thermostatically controlled outlet like Farm Innovators model TC3-3545 as long as the 120V receptacle (or thermostat) in the same general area as the battery.

No fires that I know but I did have 2 batteries swell and I had to replace them. I believe they do over heat at times but no fires to my knowledge.

Im in MA. I store my batteries in an unheated garage for several years since ive bought it....no issues thus far. But i agree that they are so small....so if you are worried, just bring them into the house when it gets really cold.

The only power supply comes from the heater/AC unit. There are no user-replacable batteries in this unit. If power is lost, the unit's memory chip holds the stored setting until power is restored.

I had mine plugged in for a few months - only using it occasionally - and one night when I wasn't using it, started flashing red in the middle of the night - it didn't turn the heat on while it did this. It didn't stop when I used the control so I unplugged it and replugged it in and it's been fine. Nothing in the manual about that. If it does it again I will call the manufacture.

Overheats? I think P.Doell has the best answer. It is hard to get the battery in correctly, but I've had no problems with heating.

Depends on the battery, if it's Li-Ion rechargeable battery you'll fry the battery.

Should be no problem. But, depending on how low the temp is, it might take longer to warm up the battery. But in the end, any heat is better than no heat.

depends on if your 12V outlet stays live when you take the key out of the ignition. If it turns off, like most cars, then the seat heater will turn off also. But if your outlet always has power, then yes, it will drain your battery.

Seems to work well but it is battery operated so if the temperature drops towards zero and below it will probably stop working because the battery will not discharge energy.

I dropped mine and the battery cover broke, but it still works. The other 2 I have, nothing has worn out, the battery is still going having not used it since last April. The heat pad is working perfefctly after 2 years!

YES YOU SHOULD BE CONCERNED. Do not use the battery as it may create a hazard. Dispose/recycle appropriately or return to manufacturer/seller.

No, when the batteries die, replace them. I have had it for 16 months and have replaced the batteries only once. Great little machine. If you aren't going to use it for a while, just take the batteries out.

I should add, when it's not plugged in or getting power, mine displays a low battery alert, then dies.

The real answer: Nothing to worry about if the current draw of the device is less than the maximum output of the battery. However, if the current draw of the device is GREATER than the battery's maximum output current, you will possibly experience the battery overheating and/or experience a thermal runaway.

I returned mine due to a broken back cover so no idea if the battery runs hot. Sorry I couldn't help.
