Remove the connection of the negative pole first!
This protects from short circuits with any metal parts of the ship.
Transportation
Batteries are quite heavy!
The battery must be transported in its original or equivalent package and in an upright position. If
the battery is in its package, use soft slings to avoid damage.
Do not stand below a battery when it is hoisted.
Use a suitable cart or trolley for long distance transport.
Please ensure a firm grip that the battery cannot fall down. Larger batteries have handles or
supporting loops. If it is too bulky, ask a second person for help.
Attention: Always set batteries down gently!
Battery installation
Usually the batteries are charged continuously by the battery charger on board. In any case of battery
replacement, please refer to the manufacturer’s instructions.
Important: Observe the removal instructions already listed.
Please note that even though the batteries have been installed correctly, there are still other potential
dangers.
If consumers are already switched on during installation, a more or less powerful spark can jump
when the battery is connected, which can ignite the oxyhydrogen gas that may have been produced
when the batteries were charged.
Important: Therefore, switch off all consumers before installing the battery!
Further sources of danger from lead batteries
-
Commercially available batteries are usually lead-acid accumulators. The batteries in a boat
work with high electric current to start the engine(s).
-
More likely than a gas explosion is a mechanical damage to the battery housing. Acid can leak
from the battery and can cause chemical burn. Be careful not to touch the acid and expose
your face or eyes. In case of contact with acids proceed as described above (rinse with water,
contact a medic).
-
Occasionally, the acid also spreads via the fingers to the face or eye. In these cases, the same
measures (see burns above) are required as for acid contact caused by the explosions
(rinsing with plenty of water; check by a physician).
Charging
In case of poorly ventilated rooms and/or multiple batteries charging at high currents (charging
station) it is possible that the accumulation of electrolytic gas can become high and the
concentration can explode.
Chemical burn
Electrolytic gas detonation can rip the battery housing open and acid can be expelled. Sulfuric
acid causes chemical burn if it is not immediately washed out with water. Intensely rinse with
plenty of water (at least 15 minutes under running water). In any case that acid gets into eyes,
rinsing with water and contact a medic immediately!
