There's always a slight drain on the battery for vehicle electronics. IMO the battery should not be dead in a week. Either your battery is failing or it's not getting a full charge. In addition, if you're running your vehicle for 5 minutes to charge the battery, that's not enough running time. IMO you need to run the vehicle until it's up to normal operating temperature & even that may not be enough to bring the battery back up to full charge. :confused:

If you're considering a battery charger, I'd recommend this one. The price is reasonable & it has 3 LED indicators that let you know what it's doing. I actually have one mounted permanently in each of my vehicles. :wink:

A short? As in on the battery or some of my installed components? Wouldn't a fuse blow if there was a short?

Wow.. that charger looks great! I may have to pick one up after I get a new batt and leave it in the car.
There are lots of chargers to choose from, but this one had eveything I was looking for. :wink:

If you have access to a DC ammeter, you could disconnect the ground wire from the battery & insert the ammeter to measure the parasitic current drain. There should be some current flow, but much less than the cabin light. There has to be some current flow for devices like your head unit (memory), the ECM & the security system. :smile:
