Jeep wont start..not battery..Help!

My jeep is my DD. But i let it sit just 2 days. Go to unlock it/disarm alarm and nothing. So i manually unlock it and try to crank it...nothing..dead as a door nail. I check and see if i left anything on but i didnt....So i put the charger on and let it charge all night. The next morning it cranks flawless. That same afternoon i go to crank and dead again..This time, the lights, accessories, all the beeps, fuel pump every thing comes on and does right. But when i try to turn it over , it just clicks and doesnt turn over. So i put in a new battery,,,no start still. I put the charger on full blast/crank start. After about the 6TH try it finally starts. Get to my destination and again it wont start.

I am praying i can get it to crank in the morning so i can take it to the parts store to run a diagnostic check on it.

What year is your Jeep? How many miles on it? Has it been in heavy rain at standing water recently? Any mods?

My guess is the starter or the alarm if it is aftermarket. I had an alarm that was kind of faulty and old, and it would drain my battery, if I left it on, over the weekend.

A bad starter will do that too. It might be taking too much power to turn it.
But, the year of your Jeep is important. I wouldn't say the same thing if you had a 2014 Wrangler.

Auto? If so can u start it in neutral? If it does then neutral safety switch could be problem.

Is your battery actually draining or is everything else working but just won't start? While rare at that mileage the starter can be going bad. I had one that had bad brushes. I would just get a click and would seem like a low battery. While somebody else turned the key, I could tap firmly on the starter with a breaker bar handle and it would start.

Check the battery connections, make sure they are tight and corrosion free. Get a volt meter and check the voltage drop at the battery when you crank it.

with those voltage readings it is the starter or the cables. The cables were a problem on my 08.

How proficient are you with a multimeter?

What makes you say it's not the battery? It sounds a lot like a bad battery to me.
Really not trying to be a smart ass, but it does sound like battery issues. Another thing you could check is the plug connections under the main fuse box. Sometimes these can vibrate/work loose, and cause intermittent problems. Also there are times when just a fuse not making good contact can generate electrical gremlins. A simple removal and reinsertion of fuses can often clear things up.

i put a almost new battery in it. Its my step dads battery he uses for the rv. Its a marine with 685 cranking amps. I guess there is a small chance both my stock and the marine thats in the jeep now is bad.

We had a no start that wouldnt turn but there was spark. Ended up being the ignition fuse. 75 cent solution.

You need to put that "almost new" battery on a load test, I'll agree with one other poster that say's it smells like a bad battery. If you have bad cells in a battery it will drop in voltage like that but a load test would be the definitive test.

Here is an old school load test procedure if you do not have a true load tester.
Connect your multimeter up and read dc voltage, it should read 12v~, turn on your high beams and watch the meter for a few minutes. If the voltage has a sudden drop from 12 volts to 10 or 8 volts than you more than likely have one or more bad cells in your battery.
This is not an end all be all test but if it does drop there is your issue.
Note; this is done with engine off.

Tried it...no sudden drop.

If it not your battery, or starter there is usually only one other option. If you can get to an Auto Zone or similar auto parts store they can check all three.

Left out the third option, alternator.

Yeah as he said above, get it to auto zone and they can quickly check for the thre most common and go from there.

Also check connections at the starter, make sure they are tight and free of any oils. Years ago, I had a vehicle that wouldn't start, checked battery cable connections, but found out it was under the engine at the starter. Just another thing to check..As Moab says, check with a meter, should be at 12 volts and will drop if lights, horn is used. Also when you get it started, check again with a voltmeter, it should go up above 12 volts if it's charging the battery.

When the vehicle is started cold; the charging voltage should be more than 13 Vdc.
A battery at rest over night should be more than 12.5 Vdc.
I would measure the Ohms resistance of the battery cables and have the alternator load tested.

Went and got the stock battery checked and the one my step dad gave me. Battery my step dad gave me was only 3 months old, bad too. He will be taking that one back to napa.

Anyways....put a new battery, with 850 CCA.......problem solved. Cranks like a champ.

Thanks everyone for prompt responses. Could have saved a lot of worry if I would have gotten my lazy _ up and gotten battery checked.
