Battery drain/dead problem

So I've been having this problem to where if I leave my truck for about 3 weeks, it is always completely dead when I return. Thought it was due to a bad connection with the battery terminal. But, I have since got that fixed and I just returned from three weeks away, and truck is completely dead. I'm guessing I have something constantly draining the battery while I'm away, but no idea what. Only two electric things I've done are a PHP tuner, and installed electric seats (lightning seats).

Anyone else experienced a similar problem with there things? My battery is an optima red top if that makes any difference.

The Gryphon should be unplugged if the truck is going to sit

Cheapest solution is just unplug the Gryphon when it sits...
You can invest in a battery tender....
Solar powered if the truck sits outside or plug in style if it sits in the garage...

Had the exact same problem the past three months with my 98 and it when i took it to the shop they said it was my edge evolution programer, so now if i ever let my truck sit i just unplug it. i just had this done last week so im still kind of skeptical but my truck will be sitting all next week so that will be the big test.

Yea, I'm thinking/hoping that was the cause. I unplugged it, and left it unplugged while I drove around the first couple days back. Battery charged fine, and no problems since.

The older monochrome Edge/Gryphon pulls a constant 0.05 Amps when off to power it's "keep alive" memory. Over a 24-hour period, that pulls 1.2 Amps out of your battery. The truck's circuits also have up to a constant 0.05 Amp draw depending on your trim level. So, in my case, that means 2.4 Amps disappear each day that the truck sits. A battery is considered fully discharged when it loses 50 Amps as I recall. At 2.4 Amps/day, you have a dead battery in 21 days (three weeks).

I use a "Battery Minder".

that explains a lot. In addition to that I have an Ipod and Garmin plugged in, and my batter goes faster than 21 days. I too have resorted to a battery minder.
