I have a 2004 Volvo V70 2.4, and recently been experiencing issues with the battery needing jumped when it sits for a few days.

I have had the battery and alternator checked, both are good.

Wondering what else could be the issue. I am currently deployed overseas, but will be home in a couple months (God willing.)

Please give me some ideas of what could be wrong, so I can attempt to have it diagnosed without having to spend a lot of money!

Thank you,
David

Sounds like a possible short. Pull the positive cable from the (fully charged) battery. Put a test light between the cable and battery. If it lights up you have a draw. Keep the test light inline, then pull the fuse to any suspect curcuit/component, watch if the light goes out. If not replace the fuse and go to the next... If it is a component drawing current this will at least give you the curcuit its in for furtber diag.

A corroded, chaffed or cut + bat. cable can also be to blame. You can isolate the hot cables by disconecting @ each end use a continuity tester to one end and other on the negative on battery. An isolated hot wire should not have any current to the negative... ever.

Another suspect could just be bad or corroded cables or conection. This will cause a good charging alternator to not deliver the charge to an otherwise healthy battery. Visually check every connection for looseness and corrosion.

Check ALL grounds also.

I.E. battery to engine, frame...engine to frame... Anywhere grounding runs.
