I'm looking to see if other owners have experienced a parasitic battery draw of .98 Milliamps?

I purchased this truck new in 2009. In November 2011 I experienced week battery issues and once the weather turned cold, the problem became more problematic.

I took the truck back to the dealership for service/warranty. After three months of multiple diagnostics; dash cluster replaced, computer flash and finally two batteries replaced, the problem subsided, until now.

12 months after the batteries were replaced by Dodge, I'm back with the same problem, battery drains overnight and she wont start. Now that I'm out of warranty, I've researched other sites and studied the causes for parasitic drain.

Here's where I'm at with the diagnosis: Acceptable draw should be .30/.50 Milliamps. I'm obviously higher @ .98. I've run through the fuses, pulling each one by one looking for a draw; no success, however i did notice when pulling the Audio/Amp (40AMP) fuse it spiked up to 199/301 Milliamps. That seeems strange.

I've contacted a local Automotive Electrical Specialist shop in town, they seem to think my driving habbits are the cause, where I'm only driving the truck 5-7 miles a day, may be the cause. They seem to think the truck is not able to sufficiently charge both battery's enough to recover from the initial start in the morning.

At this point, I'm just keeping a 10AMP battery charger at the ready.. thoughts?

 

.98 milliamps? drains two batteries over night? That doesn't make any sense to me. The batteries in your truck are probably 100Ah each so 1 milliamp discharge would take about 200,000 hours to drain them.

Driving only 5-7 miles is probably the problem.

 

I dunno about that, my commute is less than two miles (although I do idle it for about 10 minutes to warm it up) and I haven't had any battery drain problems.

Side note: You sure you've got a 2009 5.9?

 

I stand corrected, this is the 6.7l engine with factory Jake brake and recirculation exhaust.

Batteries have been on the charger for 48 hours to bring up each cell to 100%. From what I've been told, the batteries may have received a surface charge which cause them to fail quickly overnight.

I ran another drain test this morning with the batteries@ 100%, it came back with the same results 119ma / 98ma DC draw

 

Ok, that's still around .1 amp should take over 2000 hours for that little current to drain your batteries....good luck
