My #2 son gave me one of the compact lithium ion battery
jumpers/chargers after I complained of loosing out on two cruises on my
new boat due go low battery chargelast summer. It's rated at 700 amps
and supposedly will jump start a 5 liter gasoline engine. Seems small
for that but time will tell.



Don: do you have a battery on/off switch on that new boat? If the
battery is charged up before you put it away by the engine's alternator,
it should remain charged for weeks. My Parker boat outboards did...I
just remembered to shut all electrical power off via the battery
switches. I'd also drag the boats home from the marina yard every few
weeks for maintenance and if I remembered, I'd toss the batteries on the
charger.

If your boat is wired properly and you turn everything off before you
leave, the battery is disconnected.
The exception is going to be the bilge pump, if you are wet slipped
but that is a plan to fail if you don't have a shore tie or a
wind/solar charger.
That also has to be on the line side of a battery switch if you have
one.
The best answer is to use your boat often enough so the battery does
not die between uses. Living in the great white north may limit that
but my mother's family were 12 month boaters a few miles down the road
from Harry. My niece keeps her marina open all year and they still see
boaters all winter. The rock fish seem to be thick right now based on
her facebook pictures. (Stripers for you New Yawk guys)
That is a fish that really came back, thanks to conservation efforts.
I did not see one at all in the 60s and 70s.


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.
