Background: I have a 1999 Chevy Tahoe. About 6 months ago it was stolen. I got it back a month later but the person who stole it cut into the electrical system to rig up a heavy duty stereo system. I disconnected all that stuff. I now find if I don’t start my truck within three days the battery goes dead. I’m guessing there is a small drain some where.
It has a new battery in it.
My question: I’m looking for a small, inexpensive charger to keep on the battery while it’s parked in the garage. I was thinking I should get a trickle charger (because that’s what I’ve heard in the past) but I’ve read on the internet not to waste my time with them. So for what I’m trying to accomplish (keeping my battery charged), what type of battery charger do I need?
ETA: I know I need to fix the root problem but don’t really have the smarts to fix it or the money to pay someone.
