Can this charger be used as starter to jump start a dead battery? Can this be used when I need to jump start a dead battery?

No, that is a misprint or something of the sort, it is not at all suited to jump start a dead battery. However, if you were to leave it hooked up to a (nearly but not entirely) dead battery for 10 minutes, that would usually be enough to get the car started unless the battery itself is not just drained but also worn out or damaged/defective/etc, or unless it is very cold outside.

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 is totally dead it may not work. For dead batteries a manual charger works better.

No, it will not charge the dead battery. This device gets its power from car battery so it could charge your other electronic devices like cellphones, tablets, etc. If your car battery is dead you need to jumpstart it or get battery charger.

It will charge a dead car battery with in 13 hours depending on the battery's capacity. It will not jump start a car though.

Sure I do it all the time when I super charge/equalize my batteries. I usually run it in starter mode for 30 minutes.

The short answer is there's no way this battery would serve in an application for a car jump starter. It's designed to provide a very low current draw over many hours as a power failure backup. Any application for a car jump starter requires a massive current draw over a short time frame (seconds). I make no claim as an expert, but your application doesn't fit this battery.

No, the wire gauge is not large enough to handle the large current need to jump start a car. It is for low current use, like trouble lights.

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.

Sometimes the battery can be so dead that a jumpstarter does not have enough juice to turn it over. What you can do is just leave it connected for about 15-30 minutes and it will act as a recharger. This will then charge the battery enough to start the car. (Leave it connected as you start the car)

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

I'm not an expert nor an engineer. However, I don't think the Schumacher IP-125 is designed to be a battery charger. It's a jump start substitute, that also runs 12 volt items like a radio or trouble light for a period of time. A battery trickle charger is probably more appropriate for full battery recharge. Charging a completely discharged battery can sometimes be dangerous and carry risk of battery explosion, I believe. Many times once a battery has completely discharged it's no good anymore and must be replaced.

I used it to jump my Ford 5.0 V-8 and it worked. I forgot to plug it in to keep charging (you can leave the new ones plugged in all the time) and when i needed it again a month and a half later it didn't have enough power to jump the car. I plugged it in for 4 hours and not only jumped the car, but was able to use it as the battery while we did some repairs to the ignition system. It has plenty of power. There may be smaller amp jump starters that will work, but if they don't you may as well have nothing. This thing works.

No offense, but you are making a common experimental error. It sounds like you are saying your car started because you put this charger on it for an hour. That is an invalid conclusion. You don't really know the charger was the reason the car started. To determine if that was the case, you'd need to charge the battery fully, then leave the lights on for the same period of time as before, then turn them off, immediately try and fail to start the car as you did before, and finally leave the car alone for the same hour you said you put the charger on the car. Then, try to start the car. This would be a true and valid A-B experiment. I'm betting the car would start in this second scenario. Anytime a lead-acid battery is run down to the point where it won't start a car, if you shut off the battery drain and let the battery rest for a while, the battery will usually recover and be able to start the car.

First...yes. You can use this to replace your normal starting batt. Its designed to start the car and allow you to run your accesseries without the engine running. And second, No...You dont have to do that. The battery is just a energy " piggy bank". Its job is to store the energy made buy your alt and send it out when needed to what every your running inside the vehicle. The reason you get a batt like this is because it can discharge many times and not eventually degrade the batterys effectiveness over time. And it helps stabilize vehicle voltage. Its a very good batt.

I agree with Hugh & Dean. This Charger charges and monitors each of two batteries independently, so yes, one could be your starting battery and the other battery could be for accessories or trolling motor.

It's designed to be used with portable jump starting devices that usually have a cigarette lighter port on them. I've also used mine with a cigarette lighter to battery adapter like this one - http://www.amazon.com/Roadpro-Battery-Clip-On-Cigarette-Lighter/dp/B00065L2D8/ref=sr_1_1?ie=UTF8&qid=1383415417&sr=8-1&keywords=battery+cigarette+lighter+adapter - I've used it with either a motorcycle or car battery sitting on the floor of the car. If you use the battery sitting on the floor of the car method, be sure to triple check the polarity before plugging the cable into the OBD port in the car.
