I am getting about 2 AH per day out of that. 5 days should be OK with good 
batteries (for one battery). 10 days would be pushing it.
My 50 watt solar panel would easily keep up with this and keep the batteries 
topped off. Even a 25 watt panel would do.

Infinite battery life would be pretty great.

I'm mostly just wanting to know if we're talking days or weeks here. The boat 
is away and offhand I can't remember what amp/hour batteries I have, but 
they're wet 12v batteries (i.e. probably like car batteries) so I feel like we 
could estimate 45 amp hours(?) per battery. The pump draws 1.9amps and the 
'check' it does is about 1 second long, roughly every 30 seconds.

I left the boat Sunday morning with the batteries mostly full and I'll be back 
to the boat on Thursday evening. Any reason I should be worried?

How many total amps in your battery bank?

SHORT STORY: I have my boat on a mooring ball with a Rule 500gph bilge pump 
that seems to be ‘checking’ just about every 30 seconds (no idea why it’s doing 
that and not 2.5min). I’ve got a bank of two 12v batteries, pretty much fully 
charged. Roughly how long before they go flat?

Long story available on request.
