Just ordered a battery tender to keep the D's battery in good shape. I do not like to have to drag out the booster pack when the juice is low, especially in the cold!

 

Battery tenders are good if they are plug in. Are you pluging it in at night then?

 

Yes, sir! Plug ins for these cold winter nights. Gonna use the included o-ring terminal with fast disconnect and an extension to the charging pack in the garage. Wifey took over the garage, now it's a storage room. Gonna run the wire under the garage door under the hood of the D.

 

iv never found i needed a battery tender, and YES i park outside it cranks a little slower int he cold, but as long as i let the pump prime before turning it over in the morning its fired up pretty damn good IMO

 

I wish I can say that. There seems to be a slow drain somewhere and I haven't nailed it down. But if I don't drive the D for a few days, the batery dies. I know, I'll have to nail that drain down soon. The tender is a bandaid.

 

do you leave anything plugged into the power outlets inside the truck? my aunt did that to her car and came out to a dead battery if she didnt drive it for a couple days . . . just a thought

 

No man, nothing plugged in. The only things that use the outlet I have on a splitter and the splitter is always unplugged cause it has a VERY bright blue indicator light on the plug! LOL!

 

well the indicator is probably LED so it wont draw down much, i used to leave my phone charge plugged into the always on socket in the center console and that thing would sit for weeks and still start you might have a short somewhere, start pulling non essential fuses from the fuse box one at a time until you it stops draining, than something powered by that fuse is the problem

 

Or it could be a very cold outside and a warn battery. Other than that I think Sharps on the right trail.

 

Remove a fuse at a time and stick an ammeter in place of the fuse, if you get sockets with current flowing through them you need to see why there is current flowing through it when the car is off. Any normally off circuits shouldnt have current flowing. If all checks good the battery itself is probably defective.
