Okay—clean everything.It's a connection problem. Clean all the battery, solenoid and starter connections. There is a possibility the battery jas a shorted cell, after jump start they may work several times. Due a voltage drop test.
Connections issues don't normally drain the battery, but do what Thief says first.
You probably have an excessive parasitic draw.

OkayA bad connection can do that. It could also be a parasitic draw that comes and goes. Check volts at the battery every morning and see if it drops.
Fully charged battery is 12.6-12.7 VDC, engine off.
Below 12 & starter relay will just click.
Will doTake a battery voltage reading in the morning before you start it.
ThanksIf you don't get anywhere with the above, Pull the battery, eventhough new and have it load tested. It may be showing proper volts, but may have a cell going bad and not have proper amperage. You could also have a cable going bad and it has excessive resistance in it. I have a hard crank when hot issue with mine and after I put a new battery in it, if it's still there that's where I'm going next.
Good luck
Along with the suggestions made, put the multimeter on the battery in the morning and watch what happens to the numbers when you try to crank it. If it shows ~12.5 volts but drops down to ~8 or 9 as you try to start it, the battery is likely the issue.
How do you load test the battery?Bad battery.
Could be other things, but most likely that's the culprit. Easy to test. You should be getting 13+ volts from the alternator while running and all accessories off. The battery should maintain 12.6v off. There should be no draw on it when off. Load test battery. Check the connections and main grounds from the battery and engine block to the frame. If the battery is bad, you still need to check the rest. If the rest of the system has an issue, the battery may be the symptom, not the cause. But, it could just be the issue, too.
