Battery drain

[djmgn]

Few times when truck not started, doors open, and radio on, I've found that when I've hit fhe fan or put up windows I get a battery drain and will need to jump the truck. Will get many clicks trying to start it before jump.

Battery checks out, but told it had a slightly low charge.

Found that sometimes front seat will reset, or clock will lose a few hours when I've gone out next morning also.

Got a 2000 Yukon XL.

Any ideas?

Check the alternator.
