Why does battery dies when truck sits for a couple of days?

What is your question?

When I hook up charger there is a faint buzzing sound coming from a small canister near the fuse box. It will buzz for a few seconds then stops.

Since all batteries create power by a chemical reaction, we say that the chemicals have exhausted themselves in the reactions. This would mean that a dead battery is exhausted. --------- lightdeal
