Justin sez..

"I don't recommend putting your battery away by the engine's
Â*alternator. What good would that do? Better to disconnect a
Â*battery lead and check the charge every month or so. A dead
Â*battery might freeze and crack."


We were talking about the 5 month boating season.
For the seven months off season, I have the boat battery in the basement where I run a 12 v LED clearance light off it and once or maybe twice a month I'll hook up the battery charger to it set at 2 A charging rate.

Good. If you store it in the driveway during the season, it would be good to put a trickle charger
on it. These are some great little chargers, and they'll keep even the big batteries charged:

The ring harness can be attached to the battery and left there for very easy connect and disconnect.

Problem I had with dead batteries, was the battery combiner. Wired in a
switch on it's ground line. Drew 15milliamps when in non combining load.
So even a constant draw in the battery with the selector switch off.

Sounds like a horrible design

Is this on your brand new Bayliner? I'm surprised there's no battery switch somewhere. I'd for sure
take the battery out of the boat in the winter and put it on a trickle charger.

I don't usually see battery switches until you add a second battery.

Had something similar to those set ups with the Princecraft Yukon 15 that I bought from Captain Tom way back in 2007.

The pontoon has a battery on/off switch with just one battery when new. I added a second battery and a selector switch.

Standard design. Some draw a little less, some more.. Has a voltage
sensing relay to connect the two battery's together when charge voltage
reached. Our have to put a battery on off switch in each battery line or a
switch on the relay circuit ground line.

These days I would expect a FET on that front end that was drawing
micro amps in standby.
I suppose a relay hooked to the ignition switch is an idea tho.

Easy to toss a SPST in line of the ground wire.
