I just try to warn people to be careful. Anything can fail, Do not depend on the crude oxygen sensor's on those heaters to save your life !! Vent Vent Vent

Even the smallest Buddy gets too hot quickly.

A little backpackers camp stove under a heavy cast iron pan or big pot of liquid works great, but same precautions.

Did a test with the seat warmers last night. Bummed - on low they pulled 65 watts total and drained the deep cycle in 12 hours.

On the plus side, even on low they get WARM. Way warmer than I would ever care for. So tonight, after recharging the battery, I'll run just one all night and see what we have. I figure that would be close to using two of them intermittently all night.

I can see pre-warming the sleeping bags before turning in, and barely using them after that. Between good bags and small volume, we'll be fine.

You should never drain a battery!! 50% at most. If you drain a battery you will drastically reduce it's life. Electric heat can only be used with very low wattage's and for a very short time. Tried it, Been there!!

Thanks for testing them though, and posting the results. I was looking at similar seat heaters. I think now, that I'll skip them, and just buy electricity when the temp gets that low. And carry a space heater.

Jeez, calm down people...

Don't know what you got if you don't give it a try. I sure wasn't going to babysit it all night, I work for a living. Not like I make a habit of draining it - it was 1 instance.

And if my sacrifice helps others (apparently at least one) then it was worth it. And if the "going on 4 year old deep cycle-used maybe twice a year marine battery" starts to fade, well, she had a good run.

Did not mean to come off like that. I just mend to inform that draining a battery is not a good long term plan. I have drained a battery several times before being informed.

It's cool, all have to look out for each other.

Taking another one for the team tonight... 1 pad on low to see how it goes.

Got some lil baskets to organize the closets better, added hooks all over to hang stuff out of the way.

The new lights/usb adapters are awesome (wrote about them in the Electrical section). Added short charge cords and magnets so the phones stick up out of the way, and easy to use for a movie if we want, lol.

Got a new plate too - lost the last one in a forest in NE AZ somewhere... ImageImageImage

After looking at were you are located. You have a lot less demand for heat then me in Minnesota. I will be road tripping the NP in next three weeks around the AZ 4 state area. If you see this it is me.

Little better - 12 hours brought the battery from 12.5v down to 11.4v.

Good to go, the intermittent use that we'll have them on won't be near as long as that.

After some more testing, pretty sure the battery was just too far gone, so picked up a new one last weekend and started some more testing. At a starting voltage of 12.7V, I ran one seat heater on low (35W) for 6 hours and it dropped 0.1V - so I guess that confirmed the old one was shot. Feeling better that the expected single digit nights won't be a problem... :worship:

Oh good! Maybe i *will* look at seat heaters again, then. Do you have an amazon link to the ones you tested?

Godskid - I'd go for it - just did another mini test. 3 hours with both on low, tucked into our sleeping bags. They got warm enough that they shut off, most likely for a majority of the time. The voltage stayed at 12.6v from start of test to end. (I never put the charger on after the last test) The bags were too warm for me so I'd be shutting them off soon after pre-heating for 30 minutes or so. :thumbsup:

Thanks! I've left them in my Amazon "wishlist" until my next winter trip comes into view.

I hadn't thought of putting them INSIDE the sleeping bag, though. Hmmm!
