Could I use it to charge my died car battery?

Possibly. However, often a dead battery has been damaged beyond the point of being usable. Typically damage occurs when a deep cycle battery has been discharged to less than 10% of its capacity. ... Or it has lost over 90% of its charge. Car starting batteries are damaged with much less discharge levels. They are designed to stay fully charged at all times.

If your car battery is still good (able to take a charge), It will charge it. But, you will need to make your own cables and terminals to connect to your car battery, as I don't think these come with wires or cables.

I presume this would work. It wouldn't be a quick charge, but after all it is a battery charger and it automatically senses the type of battery being charged.

This would probably work fine to charge your car battery, but it would be slow. This is more of a trickle charger than a fast battery charger. There are actually some better choices out there for car batteries. I have a classic car, and I keep a Battery Tender 021-0123 Battery Tender Junior 12V Battery Charger attached to that, and it keeps the battery totally charged. If you want a really fast charge (which is harder on your battery, it will reduce the life of the battery) you could use something like the Schumacher SE-5212A 2/10/50 Amp Automatic Handheld Battery Charger.

No sir, this is not that kind of a power supply. But, you Can buy battery chargers, (a type of power supply), that will start automobiles. Just search for 'Battery Chargers' in Automotive.

You can, it will not fry the batteries. It will only charge the batter if it needs charging.

Yes this should work fine however this would be an expensive way to do that. Why not just use a battery charger?

I would think so, but I'd recommend you check with the battery manufacturer to confirm it can be charged by a conventional charger.

The wattage of this unit is too low to charge a completely dead battery. It will only maintain a battery that is already charge,preventing your battery from getting drained even when parked for sometime.

It will work but you would be overloading it in the start mode...it would be fine for charging. You probably have a 250 amp solenoid. This is an 80 amp.

Yes you can, IF the end of your charger cord is equipped with micro-mini USB male plug that also fits your phone AND your car charger can put out enough amps to charge both your phone and a battery.

all I'd say is "probably"... the standard chargers that come with the unit are just 12V 5amp, so as long as the car battery can output that current, shouldn't be a problem.. how it may drain the battery is something else, but the power consumption is pretty low (one of the benefits of LEDs), and if the car would be running, not an issue. Hope that helps.

I would say yes as long as the battery isn't totally drained. The battery needs to be charged because it's a maintainer to keep a battery fully charged all the time! I think it's to small to charge a totally dead battery. The battery tender only puts out 1.5 volts and a regular battery charger puts out 12 volts to charge a totally dead battery.

Personally , I wouldn't recommend doing that .Follow the manufacturers manual on charging methods and you should get good service from the unit .

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?

If there is, it's by no means accessible to the average consumer. The clear answer is no. You can charge this through its micro usb port and then have it ready to power an electronic off the (full-size) usb slot when needed on the go. If it dies, you get a new one. If that's a concern then get a better, more expensive one.

I probably wouldn't if it were mine. Some electronics and batteries may be damaged by a power source that provides too much current (Your charger needs .3 amps and this supply puts out 1 amp). The device I am using with my power supply is a cheapy unit that is inexpensive, so no harm if it gets fried. I am also using my power supply to take the place of batteries, not for charging batteries like you're wanting to do. My recommendation is to pass on this as it might cause damage. Good luck :-)

You can use the charger for an automotive battery, if all the battery connections and battery top is very clean. Recommend that the battery be disconnected from vehicle, so that the microprocessor is not reading the vehicle keep alive circuits! I have a negative ground battery disconnect switch to isolate battery from vehicle. Also, charger requires wall current type power source to function properly:)

I would NOT recommend that you do this.. It can probably be done but this charger monitors a battery for the level of discharge as well as the level of charge. If it were the exact same battery with the exact level of discharge maybe but I don't see that happening.. I would NOT recommend you do this..

You could do that, sure, but the idea of the charger is to maintain, not recharge. They should call it a maintainer instead! It won't charge a dead battery; rather, it'll keep a live battery from going dead. So--if you know the battery is live, you might do as you've said, but if your trailer was mine, I'd keep the battery attached to the charger full time. That's what I do, and it works. Eric
