[QUOTE="hispls, post: 8750985, member: 614752"] Most have a "peak hold" function but I'd guess any good one like that will also power down if nothing changes for a few minutes to conserve battery (all my good ones have done so). I'd like to think anything drawing enough to drain your battery while you work would jump out at you, and I'm not sure if there is some "normal" draw to expect from the vehicle's entire electrical system. Another option might be to wire an extremely small fuse in line to your amp and see if that opens overnight if there's a reason to suspect a device is turning on at random when you're not looking. Not sure how that helps you figure out how to make it stop doing something that you can't observe it doing, but there is that. Furthermore if you see a current all the time, start pulling fuses until it goes away (obviously you'll need to account for door open chime and dome lights or whatever) and that may at least narrow it down if it's some part of the factory system. Lastly, if you have deep cycled (completely drained) your stock battery a few times you have very likely seriously damaged it. Most standard lead acid batteries cannot survive many deep discharges before they lose most of their reserve capacity. [/QUOTE]
