One of my concerns is coming out after 3 or 4 weeks to a dead battery. I intend to disconnect my battery as well as have a power pack (which I generally carry anyway) to jump start if need be.

If you carry your fully charged battery with you, it can power your fish finder, GPS, running lights, etc for the whole trip, and you won't have to count and carry all those pesky AAs. Additionally, you'll have the piece of mind in knowing that no one will steal your battery while you are tripping. Just strap it to a thwart, and it will hang from the canoe on the portages. It's amazing how many of life's little problems can be solved with a little ingenuity. ;D Since you'll have the power pack, it won't matter if the battery is dead when you return. ;)
