My block heater turns on 1 hour before I leave. What is the effect of a cold, then warmed up battery, if I use this in the same manner?

I would not recommend using this the same as a block heater. A battery that gets cold, will not charge back up when it gets warm again. Get a temperature controlled switch and set it to turn on at 45 degrees and colder. If the battery is to cold when you go to start it you can ruin it. According to a Google search Cold Cranking Amp rating on most batteries are done for 15 seconds at 50F degrees, so for every degree below 50F the power of your battery drops.

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.

There is an on/off rheostat dial on the front of the unit. This would be fine if you are running straight power to the heater. I have the heater set at its highest setting and my power comes from a wall thermostat. Hope that makes sense to you.

The heater will come back on with the settings that you have set when the power goes off and comes back on. I think this is a great heater but I couldn't keep mine because it was damaged/defective.

The power indicator light comes on below 38 degrees F. Because this unit controls the power to the battery heater for a generator, I annually check its viability by putting the unit into the freezer for about 30 minutes, then removing it from the freezer, plugging it into an electrical outlet, and watching the power indicator light come on as it warms up.

Not sure, my heater works as instructions indicate. I would unplug it and let it sit for awhile. The button at the top takes a firm press, the heat indicator will cycle higher and higher and then all the way back to cold after many presses. Disconnecting the power for awhile should reset it to default 78 degrees. Mine is a 25 watt heater, so it will only heat a small tank that is in a room not overly cold. Good luck!

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.

It will wear down the battery if left in all the time. Wenleave ours plugged in while traveling, and unplug it overnight. It stays cold.

The manufacturer said in the instructions that it's ok to turn it on 30 minutes before you go to bed. I used to turn mine all the way up, then turn it down when I got into bed after 30 minutes or less. As I mentioned in my review, I noticed some mild scorching on and around the pillow area. I'm uneasy about using it now. When I do, I only turn it to 1 or even 0-1. I still use it as a mattress pad, but I have to be chilled to the core before I turn it on. I'm not making any accusations. I'm just saying use a little caution. My in-laws' woke up to discover their electric blanket in flames, so I'm a little gun shy.

i'm not sure it never got warm enough to turn off in 4 hours. the temp outside was in the mid 20's and the inside didnt make it above 40. i had to add a on/off switch it has a light that lets you know it has power to it. it drained the battery to where i had to jump start the car after letting the car sit overnight 10 hours. as i said before i would pass on this and i guess i will just chack it up and a 30 dollar lost can see them taking it back after cutting the wires to add fuse link n switch.

I have not had that problem, but this is what I would try. Turn off the heater, and unplug for 15 minutes. Remove batteries from remote leave out for 15 minutes. Replug in your heater, and try turning it on with the controls on the heater. If it stays on the problem is your remote. If that does not work do the reverse unplug everything remove batteries wait 15 minutes, plug into wall insert batteries into remote, and turn on with remote. Hopefully if it's just needs resetting and if so this should do it.Hope you get it fixed

Hey there, I left mine plugged in this winter and it completely drained it and it wouldn't hold a charge. The note on the charger clearly says not to keep it plugged in at cold temperatures. So totally my fault. I went to Batteries Express and had it replaced(well there are actually two inside of it), just shy of 120 bucks, but cheaper than buying a whole new unit.

Be sure the batteries are installed correctly. Try unplugging the heater then re-energize.

Hi Carol: I would say that you would have to turn the heater back on but I'm not sure because I have not been in a power outage since I have owned it. Sorry I couldn't be of more help.

I leave my heater on for very long periods of time, all through the night, or if Im not burning wood during the day. Just make sure where you have it plugged into the wall doesnt feel hot, I recently updated many of the wall plugs in my home.

I wish I knew, because this is a common problem. But I have a suggestion. When you are done using it, donot turn it off! Turn it on the coolest setting, zero I think, and let it cool down with air blowing through it. About 45 minutes. Otherwise you will burn up the heating element!

I leave it on. It would take a while to heat up and that defeats the purpose of having a warm "seat" in the winter. I unplug as soon as the outside temperature gets warm enough and leave it unplugged until it gets cold again. I have had no issues with it since it is plugged into an outlet with its own reset-type fuse. I hope this helps.

I am not a qualified adviser, but I don't see any reason you could not heat a battery with it IF you do not create any exposed sparks when connecting or disconnecting it near the battery and if you monitor the temperature and shut the heater off before the battery gets excessively warm. I forget whether the heater has it's own thermostat, if it does, the contacts are almost certainly in an enclosed capsule, therefore they should be safe for sparks, but watch the plugging in etc.
