Can I keep this on my car battery while I'm on vacation so when I come back I don't have to worry about a dead battery? I live in a cold climate area.

I think that it would do a great job of keeping your battery at tip top charge and condition. There are several settings that you can use when setting it up for you use. It will even pulse the battery to reduce the amount of sulfation that builds up on the battery plates making your battery operate as nearly new. The capacity for this model is 3.5 amps max, but don't let that confuse you, it operates incrementally and will also show you where the charge level is using LEDs. If there is a power failure the unit retains its settings and can be left connected even when not in use. There are mounting screws provided and two different types of connection configurations; hard wired with lugs (recommended) and clamps that are similar to those on jumper cables, but smaller. You can unplug the lug end that goes to your car battery and plug the clamps wire into the output and it will charge any battery from 6 to 12 volts. this is the best system I have ever used. Enjoy!

Yes, it will regulate itself to not overcharge the battery. However, I would personally consider an unattended charger to be a fire hazard.

Yes, you can. I used it to recharge to my car battery. It will automatically shutoff when your battery is full, and turn itself back on if the charge in the battery drops.

The manuals for these typically say "Recharge after each use as well as at least once a month even if not used". I've had a similar one for 10 years and by following that it still works well. Beware that if this is cold from being kept in the car, it will perform much poorer than being brought out of a warm building (yet it may still help enough to get you going).

This question cannot be answered because it all depend upon what type/brand of battery you use and how you use the device. My recommendation is to use brand name batteries such as Duracell Ultra and not keep the device turned on until you are ready to head back and keeping an extra set of batteries handy could be a life saver. Bear in mind that this device shouldn't be a heavy power consumption device anyway.

I have not tried that, but you may not leave it in the car if the temperature is too high. The external materials may support high temperatures but not sure about the battery and other internal components

I have these battery for a few years, it is great, with the purchase got the charger with the adapters. I take long vacations and with two of these battery I have no problem. I found that the regular in cold weather they discharge and after a few pictures you need to change the regular baterries. I hope tis is helpful.

I honestly don't know; I keep this in my get home bag in the car and simply check the batteries monthly. I have never had an issue.

Yes, you can leave it plugged in 24/7. If you were not going to start your car for a month, you might want to unplug it, but even then, it wouldn't use enough power to drain your battery. If you have a digital watch, think how long it will run on it's little tiny battery. Just about the same thing with this little voltage meter. I have mine in a boat and I never unplug it.

I would recommend unplugging when not charging. I plug mine into the charger every couple of days while driving and it has never run the battery down dead.

Assuming your car doesn't send power to the 12v outlet when it is off (and most don't) it won't drain your battery. I left mine plugged in until it died and never had any issues.

I use mine on the oil pan on my race car. It doesn't have a thermostate. Therefore it may get to warm for a battery. Depending on the weather.

I can't imagine it being an issue but not really certain. I would think the device would drain before putting a dent in your car battery. Use to have an Expedition that was always on and never had any issues when things were plugged in.

Yes. Just keep it plugged in 24/7 and you wont have to worry about the battery going dead or having to reconnect it.

It has a cooling fan that runs constantly so I unplug it. The batteries seem to hold a charge for a long time so I don't bother leaving it plugged in. Most of the time it rides in the trunk of the car anyway. Take care

I also leave it plugged in when not in use, keeps the battery from depleting during the loong winter

Always have a back up battery for trips or special events. You may not have time to complete a charge when doing a lot of sightseeing when traveling. In the event your battery may be getting toward the end of it's life, it may require more frequent charges. You don't want to be with a weak battery on those special occasions

I have owned several and they are safe to leave unattended on my houseboat in the winter, but always plugged into a grounded wall socket. They pull too much voltage to plug into a cigarette lighter i would think. could drain your battery very quickly and maybe even short out the heater.

Yes it will. You can leave it hooked up during the winter, and it will keep your battery good as new. As your battery discharges it will kick on and maintain it to a full charge. Hope this helps.
