    I'm thinking about buying a 12 volt pump that draws 1.8 amps for use at home to do a little garage prospecting. Rather than get a battery for it I have a Radio Shack unregulated 12 volt 1.75 amp power supply. Would that work in place of a battery ?

    The best battery for your dollar is to buy a Gel Cell Motorcycle Battery from Wal-Mart, these things last and are sealed so you never have to worry about them, plus small and light enough to be backpacked into a river area.

    If you are intending on needing DC for the garage on a regular basis I would just buy a Radio Shack Transformer, they are inexpensive and not only have a car jack but also a positive and negative connection so you can wire up anything DC. I still run my HAM Radio and a few other items off of it, as well as charge other hand held equipment.

    I misread your question so let me apologize, I have a 10 Amp DC power supply from Radio Shack. the 1.75 might work but it might not, or it may overheat your equipment, there is no way of knowing without trying. I have bought batteries just below the amperage needed and had them work, so I don't think this will be different, just my opinion.

    I think I will look into the battery idea next time I go to Wal-Mart. The power supply I have is for something else and I don't want to keep moving it. Plus the battery can go into the field if needed.
    Guess I'll need to look at chargers also.

    Thanks, Scott

    If you are like some just buy a small trator battery as they are cheap .But if you can get a 24 case battery you will be better off .Buy a beep cycle battery .The supply you are talking about is lower than the draw ,so it will not hold up .Will burn your pump up.

    You might want to get an inverter. It will turn 110v to 12 v DC. Radio Shack carries them.

    If looking for a battery charger the best multi use battery chargers can be found at hobby shops. They allow you to choose what kind of battery you are charging, they are very small, and they can be attached to your vehicle battery while running to charge batteries on the fly, and quickly at that. Or you can use them at home just plugged into the wall. Just make sure you follow the guidelines on charging, you can blow your batteries by charging too quickly and if you use them on a Lithium Cell make sure you keep it away from everything else, they sometimes do explode with a hot charge.

    Also, go online to Batteries Plus website and they will hook you up with exactly what you want, I have bought many medical equipment batteries from them that were custom builds. They also sell chargers and a wide array of quality equipment. The nice thing about them is that you tell them what you want and they can make it happen.

    Scott,

    I'm wonder why you would consider a 12v setup when you have 110v available ? 110v = less moving parts.
    I can see 12v for out in the field clean up, but why in the garage ?

    I use a 110v for my recirc sluice in the backyard cleanup.
    A small fountain pump works nicely.
    Add a valve to regulate flow.

    William,

    I'm thinking about getting a gold dust concentrating table that comes with a pump. Rather than buy a battery and charger for home use I thought it would be cheaper to use house power. Now on the other hand,
    if I use it in the field I will need battery power.

    I do use a submersible pump for my sluice here at home and regulate the flow. I don"t know how many gallons per hour it moves and don't want to regulate the flow so much that I burn the pump up. The table uses very little water. I do have a very small fountain pump but it just does not have the volume I need.
