Since I'm traveling for two and three weeks at a time lately, It's near impossible to keep the battery charged enough the be able to crank the engine when I'm back home. That little voice inside my head is telling me that letting this thing drain down for 2 or 3 weeks, and then jumping so I can let it run to help charge the battery back up, may not be a good thing for the battery...

I have a heavy duty charger and Jump, but I was wondering whether or not it makes sense to buy a decent battery Tender or Trickle Charger as well.

How long can you realistically let it stay connected to the Tender?

What are your thoughts? What would be your picks for the better tenders?

Thanks,
