WARNING! Danger of explosion! The batteries
give off hydrogen gas during charging which
when mixed with air can form an explosive gas -
oxyhydrogen A short-circuit, naked flame or
spark can cause a large explosion. Ensure that
the ventilation is good.
WARNING! The battery electrolyte contains
extremely corrosive sulfuric acid. Protect your
skin and clothes when charging or handling
batteries. Always use protective goggles and
gloves. If battery electrolyte comes into contact
with unprotected skin wash off immediately
using plenty of water and soap. If battery acid
comes into contact with the eyes, flush immedi-
ately with plenty of water and obtain medical
assistance without delay.
If the battery has discharged it must be charged. f the
boat has not been used for some time charge the
battery and then trickle charge it (see manufacturer’s
recommendations). A poorly charged battery will be
damaged and may burst in cold weather.

with the battery charger carefully. To avoid
electrolytic corrosion when an external charger is
connected, always disconnect the battery leads
before connecting the charger.
When charging, unscrew filler plugs but leave them in
their holes. Ventilation should be good, particularly if
the batteries are being charged in an enclosed area.
