Ignition Protection; Battery Switch - Sea Ray 260 Sundancer Owner's Manual

charged batteries can withstand hard freezing
temperatures, the idea is to increase the life of the
batteries by minimizing unnecessary stresses.
In all cases the battery voltage, specific gravity and
the water level should be monitored periodically
during storage.

Sometimes a battery may get left off a maintainer.
It is paramount to give it a full charge before
attempting to embark on a voyage. Most batteries
will take 48-96 hours to fully charge depending on
chemistry, technology, depth of discharge, capacity
of maintainer, and general health of the battery.
When preparing to restore batteries back to
operation within the boat, it is paramount to test
the batteries to ensure they are fully functional.
There are two primary aspects to consider - State
of Charge (SOC) and State of Health (SOH). A
good test device will determine if a "surface charge"
is giving a false indication of a good charge state.
SOH is not as common as SOC but does indicate
remaining useful life of the battery. A test device
measures the internal resistance over a frequency
range to give you a SOH reading. While it would
be prudent to replace a battery if SOH is greater
than 50 percent, do not put a battery into service
that has less than 30 percent SOH. A battery load
tester is a general indicator of a battery's ability to
provide a cranking current, but it is not as accurate
as actual SOC and SOH readings.
Another item of consideration is the quality of the
connections being made to the batteries. Inspect
for corrosion and poor terminal connections (crimp,
corrosion, strand breakage, etc.) prior to restoring
batteries to full operation. As required, ensure
battery cells have adequate electrolyte fluid levels
(use only distilled water and no metal funnels)
and use a silicone grease on the battery post
terminals.

All electrical components in the engine compartment
must be ignition-protected to avoid the possibility of
creating sparks in a gasoline environment.
Protective terminal covers, such as rubber boots
on electrical connections, must be in place when
engine is operating or when working in the engine
compartment.
! DANGER
GASOLINE VAPORS CAN EXPLODE
Use ONLY Marine-rated parts to replace such items as
starters, distributors, alternators, generators, etc.
Do not use automotive parts for these components
or any jumper cables because they are not ignition-
protected and could cause a fire or explosion.
Jumper cables are not ignition-protected. DO NOT
USE jumper cables in the engine compartment. The
engine compartment may accumulate dangerous
explosive gasoline fumes/vapors and hydrogen gas
from batteries being charged. A spark produced
when connecting a jumper cable can cause an
explosion.

NOTICE
For safety and convenience the following items are
not shut off by the battery switches: Bilge pumps,
Sump pumps, Stereo memory, Impressed current
cathodic protection, Engine control modules,
and Battery charger inputs. These items need
constant power to perform their task. This allows
the bilge pump(s) to operate anytime excess fluid
accumulates in the bilge, which can occur when
the boat is docked and unattended.
The battery switch isolates all battery power to the
boat, with the exception of the equipment listed in
the NOTICE above. The battery switch also provides
a positive disconnection of battery to protect against
starter engagement and battery rundown.
If you are leaving the boat for more than two hours
and the boat is not connected to shore power
