I hooked up the meter to check amps. After about 5 minutes, the draw settles down to about 43. I came back about 45 minutes later and it was at 1.

Though I don't know much about using a multimeter, so is that 1 miliamp or some multiple of 1?

That scale is 2000 ma ( or 2 amps) max scale so those measurements are 43 ma & 1 ma. Thats not a problem. Are you having a problem with not starting or are you just worried about the drop. Your battery is probably around 700 amp hour rating which if it is 700 ah that means your battery will supply 700 amps @ 12v for 1 hour, or 70 amps for 10 hours or 7 amps for 100 hours. Or your 43 ma for 16,279 hours. Unless it's causing a problem I wouldn't be concerned about the slow drop.

Three times in the past 3 months I couldn't start.

In August, when I was parked for 8 hours in the middle of the day, but I left my phone plugged into the charger all day. I needed a jump start.

Twice in the past week I went more than 24 hours without driving the truck, and it needed a jump start in the morning.

About a month ago I ate lunch in my car with the radio on. I sat there for about 30 minutes. I went to start and it was really weak. I thought it wouldn't start, but it just barely did.

As indept said those readings are perfectly normal. I’m my experience anything around 50ma or lower isnt going to kill a battery. So it’s either an intermittent draw that’s much higher or the battery has issues.

Even if the battery load tests fine it could still be faulty. I’ve replaced quite a few batteries at work that will charge and load test fine but would go dead after a few days.

Slight update. When I had been checking my battery voltage throughout the week, I think the highest voltage I ever got was 12.6 volts.

I put the new battery in today, and after driving it for 30 minutes, I checked the voltage and it was at 12.99.

So maybe that other battery was bad, even though it was just about a year old.

On my 2011 2500 big horn I installed a marine battery isolator with a on/off switch.
Cured having a dead battery after 2-3 days buy just turning the switch off and no power could be drawn from the battery, it also worked good as a anti theft device.
If you don’t mind me asking, Where did you get one of these? Interested in this.
