How long can you leave the car off until the battery no longer starts the engine?

Are u asking with a system running with the engine off or the battery just sitting there not being used in the car?

Your car will start it won't kill the main battery. ....this is a good choice

Over a year, I updated to the kinetik Hc2400, I haven't had to get another jump ever.

If you have a 12 volt battery NO PROBLEM. I have it on a BMW and I plug it in if I'm not going to use it for days. I also have it on a Motorcycle. YOU MUST DISCONNECT BATTERY TENDER BEFORE STARTING UP.

No, I think it is good for a max of 8 hours or it will kill your car battery. I generally unplug it when I go away from the car for more than an hour. I will not warm up that much over a period of several hours. This is my second one and I love them.

No off until the battery is dead 5 years from now. If it shut off it would need a wake up that was always active so it stays on.

Yes, but you still have to unplug it when you start your car. Also if its anything like the one of got it wont last more than a few hours anyway.

I leave mine plugged in all the time with the blue light still on and have had no problems but my car doesn't sit for more than a couple days without being started.

Over 8 hours, this blanket will draw almost as much capacity as most smaller car batteries have, and that's not including other things that are running, since you most likely need to leave the key in the ignition.

Good question! You can charge using the car's battery for power, but the ignition key will need to be in the "accessory" position (engine not running). However, the mfg. recommends you start the engine every few few hours to charge the car's battery up again. If the car's battery drains down to 10.5 volts (12 volts is full charge), the Energizer will shut itself off. Hope this helps.Bill R.

Disconnect your battery cable for about 30 seconds and reconnect it then drive normally. Hopefully the light will stay out and depending on your car type it may not have to do too much re-learning. Check your manual first to see what it says you have to re-set after a dead battery.

On a 12v car battery. While the vehicle is running, it should be 13.5-14.4V and while off, should be 12-12.5V

Just connect it to the battery then start it up. However, make sure the mpower jump it cables are making a good connection or it might not start. Once it starts remove the cables right away no longer then 30 seconds that is plenty of time. Because the car charging system puts out more current then it can take.

If you wire the system to the ignition so when the key is off the power is also off so it won't drain your battery

If the car's power port is on when the car is off, sure it'll work. Its fine to use it for a couple of hours while the car is off (depending on the health of the battery), but I wouldn't use it for more than 3 or so hours without starting the car.

That depends on many factors such as age of battery, outside air temperature, and extra weight due to add-ons. In general, you can expect between 6 to 8 minutes. It's very important to notrun the battery down below 3.70/3.74 volts per cell.

You can leave it plugged in but be aware that due to the budget construction it has minimal protective circuitry and could have a short lifespan running constantly, and that many vehicles have powered OBD ports when not running so it will gradually drain your battery. Estimates for current vary but are generally between 50mA and 100mA which isn't a lot but is enough I wouldn't leave it plugged in for more than a few days without running the vehicle to keep the battery charge level acceptable.

Yes. We had read not to let it run more than 4 hours as it may drain the battery. Our longest run time was just over 5 hours. The car started up fine and everything was still cold, as it should be, inside.

If you are talking about starting the car, then yes you leave the cars battery cables attached to the car's battery. Word of warning: The one thing that will kill this unit is if you leave it attached to the car for more than a few seconds AFTER the engine starts. The alternator in the car will go to full charge which is more charging current than this unit can handle. One of the guys in my shop left one attached and went to the parts dept. It was physically destroyed when he got back. So start the car, and disconnect the unit.
