My question is NOT about jump starting but if this device has enough power to backup entire car when battery is replaced with new one.

I threw this away years ago. It does work if given enough time to charge the battery. Calling AAA is faster, but this is better than nothing. Since this is s "trickle" charger my guess is no, but I'm not sure.

The charger can backup your radio station presets and those sorts of things if that's what you mean. Usually 9 volt batteries are used in the same way at autoshops when replacing the battery.

Yes, when the 12V battery is connected to another via the jumper cables the power is "shared" both ways. When you first connect it up to a drained car battery, there will be a fair exchange of power where this unit will "recharge" the car battery some (yet I think of that like connecting 2 buckets of water together and watching the levels equalize since both have a limited amount they carry). If the car is running the alternator's charging power will go into this (as well as it's own battery) or if it's not running then this unit can help start the car. If you have this unit plugged in to AC power to "recharge" and had it connected to a car battery, it will send power to both, just beware that the &lt;1 amp trickle charge can take 12+ hours to recharge this alone (so recharging a car battery as well can take 48+ hours which may seem so slow to you that it makes you think nothing is happening). If you don't mind the time it takes, that will work, otherwise if you want to charge a car battery in under 12 hours you'll want a car charger labeled 5-10 amp output.

Yes it has the setting to jump start. Of course that comes with the caveat that you haven't drained the battery too far.

Not to run contrary to the folks providing all the technical expertise, but I have personally jumped my own car (4 cyl engine) from a rechargeable unit much less sophisticated than this AND plugged into the cigarette lighter/aux socket. Again, it was not this particular unit and, per the instructions, you had to wait several minutes. But it worked perfectly.

Wellll, Yes it can, but you don't want to do it.Google and instructables dot com would be your friends here. At a high level the steps are:1. Identify + and - connections on battery.2. Break open battery case (preferably a dead one).3. Remove batteries.4. Add wires to battery contacts.5. Connect wire to a 12 volt DC power supply with 'enough' amps, or to your car battery (better watch that polarity!)But given the fact that a new battery is around 35 bucks - it aint worth doing.

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.

I would think. I use it to jump my motor home which is stored. This has a lot of power and jumped a dead battery instantly.

Absolutely not, it only takes a few minutes to pump up the tires. Your battery would have to be in very sorry shape to run out using this device.

Generally... NO! If the battery has some charge left in it, the fifty additional amps may be enough to start the car. If the battery is totally dead, you will need to charge the battery for a while. Don't forget that the "cranking" current is several times 50 amps, hence the availability of the chargers on wheels that can supply this kind of current. Dave

You must supply a power source, so battery backup would be a good option to think about.

These units are meant to jump batteries that are barely dead, like a car you drive every day. They simply don't have the power to start a car that has been sitting for any length of time, none of the devices in this price range can. I'm not sure any of these devices at all can.

In order to recharge the car's battery, the Simple Start unit puts out a higher than normal voltage that could damage other products. I wouldn't risk it, even if you find a way to wire up other things. If you need a portable cigar lighter socket, try a portable starter pack or similar product that has a 12V socket.

Sure it can. This one is usually larger than needed, but if you want almost a full week of backup this would be fine. Seven amps of capacity is usually more than the factory original. I used it for an electronic lock and was much more than I needed. Cynthia, just make sure you have room for the larger battery. Make sure the plus and minus wires are correct when you install it.

This can provide some power for "jump-starting" any car, but realize that the battery in this is the size of what you'd see on a riding lawn mower or generator. Since it's really not that big, I find the "Gives you 500 amps" labels a pretty big lie. I hooked up another brands unit like this to my car and disconnected the regular battery to try it out. It started the car (ford festiva 4cyl), but the starter was slow barely going. I believe this has a 18 amp hour battery just like mine. If I had a fully drained car battery (like from a light left on all night) and I left it connected while hooking this up, I'm afraid the drained battery would "steal" most of the charge from this battery and probably make both too weak to start the car in as little as 30 seconds. So I'm not keeping my hopes too high on these, especially if talking about a fully drained car battery (whereas if you left lights on while in a movie for 2 hours it has a good chance of starting it). Feel free to look at reviews (both some low and high ones) and see if others suggest about the same thing. Also FYI if you want a way to compare these to your car/truck battery, here's one OEMs definitions of rating batteries: CCA (Cold cranking amps) = The discharge load measured in amps that a new fully charged battery can deliver at 0 degrees F for 30 seconds and maintain a terminal voltage greater than 7.2 VDC. CAA (Crank assist amps) = The discharge load measured in amps that a new fully charged battery can deliver at 70 degrees F for 5 seconds and maintain a terminal voltage greater than 7.2 VDC. These battery packs are labeled using the CAA system, so to convert to CCA dividing the "500 amps" by 6 will give you a closer number (and I get that 6 factor from the 30 sec test of one versus 5 sec, not to mention temp factors).

Yes, but because of the voltage requirements make sure you use the device while the vehicle is running or you risk quickly depleting the car's battery.

No you need a trickle charge unit for that. However it is a great jump start system.

Hello. Once fully charged, as long as it is not used at for any type of charging, it should be able to jumpstart a car for at least 6 months. Thank you.
