Is it possible to use this to "charge" a car battery thats is completely drained? Like... some sort of trickle charge?? Sry if a stupid questions!!

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.

You can use this to jump start your vehicle and if the vehicle's battery is still good then letting your engine run for a while (usually 30 to 45 minutes) should charge the battery. If your battery won't hold a charge then its time to replace it. I don't think you will have good results trying to charge a battery directly off of this. This jump starter is basically just a battery itself that you can recharge by plugging into an outlet.

This unit may get the car started but the unit is not intended to be used in that manner.

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

I believe it should work. Typically, trickle chargers don't have a high current capacity, like the charger you're considering. Harbor Freight often gives away a small trickle charger that I doubt has the capacity yours has and it works OK left on a car battery overnight or longer.

You can charge that if you can get it to work. I was not able to charge a single battery with mine. It keeps shutting off like it is overloading or something. Total junk. Buy something better. You get wht you pay for.

The question posted by Barbara Kennedy was "how fast does it work?". This is a battery maintainer or float charger. It is not suitable for recharging a depleted or drained battery so charge time is not normally discussed relative to this product. If you need a proper battery charger there are many better suited to the task than this product which is aimed at keeping full charge in a battery that is used in a vehicle which is not frequently used.

This probably could charge a battery in a pinch as long one doesn't walk off and forget about it, but isn't something to use for off season charge maintenance. Apply the cost of this to a charger design for off season maintenance.

They don't make that point clear in their advertisement which is why I bought it. The paper work included with the charger states that is does NOT work on a drained or dead battery. Save your money and get AAA instead. They are always able to start the car for you when your battery is dead!

This battery pack could be used as the "source" for some "jump-start" devices that use the lighter outlet for connecting the cars together. However I'll add a few comments about using those lighter connected "jump-start" devices. First, several such devices like the Wagan Jumper item 9796 will draw more power than they deliver to "pump" the power, thus they waste some of the energy being transfered. Also they only work if you have a good battery in the car that accidentally got drained, so if the car battery won't hold enough of a charge to start the car, you'll never get going from the "trickle charge" they provide. Those also can take 15-30 minutes to give you enough charge to start, so don't be expecting to plug it in and 30 seconds later to be turning the key to start. Speaking of the key, you also need to have the key in the "accessories" position while charging the car so the lighter is connected to the battery in the car, but you're not draining power with the cars engine computer running like while in the "on" position. So with all of those issues, most don't like those lighter "jump-start" devices (look at the reviews of such), but that doesn't mean they don't work for some.

Yes you can but not advised. It will go down to a trickle charge when batteries are fully charged. ok

Yes! it is excellent for car batteries and will maintain the charge without overcharging. - Len - 661-245-2000 - Racecrafters-USA

I would say yes to deep cycle battery charging,no start mode.it won't charge a completely dead battery,it has to have at least 7 volts I think.i thought that was odd but that's the way it is.

I bought a trickle charger that automatically shuts off when fully charged so as not to overheat the battery. I never paid attention to how long it takes, but would recommend investing in such a charger to save the battery. The charger can be used for other batteries as well.

Yep. http://www.batterychargers.com/ProductDetail.aspx?ProductName=94026805ACP As the float a.k.a. trickle charge is very low current, it's best to disconnect the battery from the car when it isn't driven for extended periods.

Yes, if battery has not gone bad, and you have enough time- it would take many hours to fully charge a car battery. I have used it to recharge a large battery and over several days it will finally switch to "maintenance" mode.
1988783
Yes. I use it to charge/maintain a car battery everyday. It might recharge a battery but it would take a long time if it was discharged.

If you have an AC outlet in your vehicle you should be able to do it. I would recommend having the vehicle running, so as not to drain your battery. It only operates on AC.

It's a very slow trickle charge. It's great for maintaining batteries but if you have a dead battery and are in a rush to charge it this is not what you need. I'm not sure but I would guess my unit would take a day to fully charge my car's battery.

No, it's only for charging any 12 volt automotive type battery. That includes flooded acid, AGM, GEL but not dry cells like odyssey batteries. They use a much higher amperage charger. The reason you cannot use this to run anything is because it charges by sensing voltage in a battery and runns a program depending on each of the 3 battery types I mentioned above. It will charge 1.25 amps until 80% of float voltage which is 80% of 13.2 volts except the GEL that's a little higher and then it cuts the charge rate to .13 amps for about 8 minimum hours and won't stop until 72 hours have elapsed. In most cases batteries are charged in 8-12 hours. If you discharge the battery while it's charging it messes up the program.
