120V in 12V at 3amp out power pack be used as a trickle charger or will it just create smoke. Sorta leary of them since I plugged the wrong one into my cooler radio and generated more smoke than the radio could handle.

Thanks everyone--good points all-may attempt to keep or usually for me let the smoke out of this box.

No a transformer will not work as a trickle charger. For the transformer will produce that 3 amps at 12 volts 24 hours a day. It will not shut off when the battery has reached its peak charge and this will cause the battery to boil all of the water out of and destory it in just a short period of time.

Just go to Walmart and spend $17 for a battery maintainer.

Well yes that is a good way but I am wondering if I would be getting the same thing in a different package. Not being one to discard things untill I am sure that they are no longer useful. Maby someone has one of the battery maintainers and can post the output volts and amps. Thanks for the response.

You can use the 12vdc@3amps for a charger if you keep a couple of things in mind. you will need to limit the amount of current to something less than the 3amps if that is the value shown on the unit. Value's shown on such units are the max. short circuit value and will smoke the unit PDQ. I would limit the current to less than 2amps. Use a resistor in the positive lead of the power pack to limit current. E(12volts) divided by I(desired current) equals R(resistance) for value of current limiting resistor. Use a resistor with at least a 10 watt rating. Radio Shack has this type of resistor although you may not be able to get the exact value. A 10 ohm 10 watt would let you charge at a little over 1 amp. If this is a trickle charger 1 amp will work to maintane a charge on a typical automotive battery.
The only problem I see with your idea otherwise is that 12vdc is not really enough voltage to keep a 12volt battery charged. You need to have a charging voltage greater than the battery voltage. I build mine to deliver between 14 and 18 volt's. Try it with your power source and it may be okay. You will only be out the cost of the reistor which isn't much. Larry

I have 4 of them..they're maintainers...not trickle chargers...they only will charge when the battery runs down a bit and they'll charge at 1.5 amps until fully charged and then "maintain" that is, on and off as needed. You put a trickle on it and leave it, you stand a good chance of boiling over the acid if you don't monitor it. A "maintainer"/"float charger" automatically works only when needed. Buy one and don't mess around taking a risk. You're not going to save a penny if you mess up the battery. Wait..I have 5 of them....boat batteries, tractor batteries...
