does this jump start a dead car battery?

Schumacher told me that if the battery is dead to connect it to a good one in a nearby vehicle for about 15 minutes using jumper cables to get the dead battery up to about 3 volts because their products won't charge a battery that is "dead-er" than one having less than 3 volts in it. After the 15 minutes, you can detach the jumper cables and use the Schumacher unit to increase the charging of the battery.

No. It only charges batteries over time (depending on how low the battery is). I'm not sure if it would charge a totally dead battery.

It can over time. It doesn't happen instantly. It takes a few hours to charge the battery enough to start it.

It charges a weak battery. If the battery is, for example 50% charged and it only takes several minutes to bring it back to 100%, some cells of the battery are dead rendering it useless. Won't jump start a car, not it's purpose. There are chargers/ jump starters, but be prepared to spend more $. It will, however,serve as a maintainer should you plan to leave the car sitting several days. It's all in the instructions. Be safe, read the instructions. On rare occasions batteries get hot (to the touch) meaning they are going to explode. I always touch the battery after a half hour or so.

No. It's meant for charging and maintenance and only has the options of 2,4 and 8 amps. There is no mention in the manual of using this for jump starting. I don't think the wiring could deliver that amount of current. I have a 40 year old charger starter that I use for jump starting and a portable Schumaker mity-mite as well for that purpose.

This isNOT a jump starter. It's a maintainer and a darn good one. It puts out a max of 4.3 amps. You need 30 amps to jump start. If you put this unit on your TV all the time you won't need a jumper, and your battery will last a lot longer.

If you connect up the jumper cables to another battery and plug it in, power will go to both batteries. However it can take 12+ hours just to recharge the battery in the jump-start from the 1/2 amp charger provided, so recharging a drained car battery can take 3 days to a week off of that. So with it taking so long (that is likely to make many think nothing is happening) most OEMs say not to do that, but it doesn't mean it won't work.

No you will have to run a remote wire from the fuse box they do make a adapter to jump a fuse.

It will draw power from the car battery but the alternator will recharge it fine. Only issue would be if you recharged it a few times without running you car. Then you might have to get your car jumped!

I believe some battery drain does occur. I had multiple occasions where I tried to start my (new) car and the battery was dead. However, this was after at least 1-2 weeks of no use.

Consider purchasing a $20 power source (e.g. Walmart). This is escentially a battery with its own clamps to hook on to a 12 volt battery to jump start it, but it also has a cigarette lighter plug in. Use your 12 volt car pump plugged into this and you'll have the speed without being tied to the car. The unit is also great for a jump start if ever you need it.

I not sure but we have never damaged a charger by accidently hooking it to the battery wrong. You would more likely risk explosion or damage to the battery or sensitive electronics in the vehicle you are jump starting.

Yes, it can jump start 24 volt vehicles. The front switch has three positions, 12v, off, and 24v. By the way, the DC power outlet is always 12v, even if the switch is off or in 24v mode.

So my question I guess would be is -- if I left my lights on and car battery died overnight, could I just hook this thing up and within a few minutes, startup my car?

Hello AlexisIn answer to your question about performing battery charging, and jump starting the answer is yes to both. I personally have used both functions with this charger. I inadvertently closed my seatbelt in driver's door which completely drained the battery. I used this charger for approximately two hours to recharge my battery which it did. After the charge I had no other problem starting, or operating the vehicle's devices. I have also jump started vehicles with this charger. It performed both functions. It also has a compressor to air up your tires.

No it states in the instruction DO NOT USE TO CHARGE A CAR BATTERY OR JUMP START A CAR

No. There are other chargers that provide a "jump start" option if the battery is dead. This CTEK charger will prevent a battery from becoming dead. And, unlike other "float chargers", you can leave this one attached ALL the time - it won't over charge. The CTEK is a "smart charger", perhaps one of the smartest ones a consumer like you and I can get.

If it's fully charged, it should be. Jumped my dead Subaru Legacy Turbo with this thing.

No! It plugs into a 12volt outlet and uses the battery that starts your engine.

so this solar male to male can jump start me car from inside without having to go under the hood?
