At what amperage are you charging it at and are you sure you have a good connection on the battery charger?
At 10 amps it would take a few hours, at 4 amps, maybe all night to charge the battery fully but that depends on just how drained the battery actually is. If it is just low like around 10 volts or so, it should not take long.
Do you have a voltmeter to test the battery voltage?
If so, see how much it is.

Currently I have the charger set on 6 amps, 12 volts. the meter shows it at about a 2 now but seems to be coming up. Should I just leave it on charge all night?

Pretty sure I need a new battery if I can just get it started to get it to the Caddy Shack.

The battery is only reading 2 volts?
That is basically completely drained.
You would get a better charge from another vehicle's battery if you had jumper cables.
At 6 amps though I would not be surprised if it took 10 hours to get it back up to 12 volts.
Then you will have to find out what is causing the battery to drain.
Just in case something was left on, you should probably unhook the negative battery cable so the charger does not waste energy turning on whatever was left on.
If nothing was left on, then you will have to check for a short after you get the battery recharged.
you might also get lucky and do not need a new battery.
A battery can go drained and recharged numerous times before it actually goes bad.
Once you get the battery back up to 12 volts, walk all around the vehicle seeing if any lights were left on, inside or outside, radio, etc.

Yes Sir. I will do all the above. Being a battery that is nine years old, I hope it just needs a new battery. Just have to get it charged up enough to get it started. It is straight in the garage and my jumpers will not reach my other vehicles to give it a jump. I will let it charge all night. Would it be better if I set the charger on 2 Amp charge instead of 6?

Earlier I said it meter on the charger was showing 2 volts. Wrong. I meant to say it is showing 2 amps.

Yes, 2 to 4 amps all night.
I do not see why you could not remove the drained battery, then set your drained battery on some wood close by the other vehicle, attach the jumper cables then and charge that drained battery for about thirty minutes while sitting in the drivers seat with your foot on the gas revving it up to about 1,500 rpm.

It looks like trying to fit a submarine in a tea cup to try and get the battery out. So much junk under the hook. Thanks for all your help.
