1. Check the cause of a dead battery
(1) Forget to turn off the equipment, the boat may not turn off the equipment such as lights when people leave, the battery will continue to supply power to these appliances until the battery is dead.
(2) off-season mooring, such as winter boats can not be used for a long time without the use of the battery will also slowly depletion of battery power.
(3) Battery lifespan, if the battery has not been replaced for too long battery capacity and voltage will drop, can not start the engine, then should be replaced in time with a new battery.
(4) battery corrosion, lead-acid batteries for a long time plus the boat for a long time to make the battery in a humid environment will accelerate battery corrosion, this time to wipe away the corrosion and then try to battery whether the power, no power is the battery has been corroded to the point of unusable.
(5) battery rupture, marine batteries for a long time in the vibration of the stronger water, may lead to loose screws, battery shaking impact rupture electrolyte leakage will directly lead to the loss of the battery’s ability to store power, should be replaced before the battery to remove the leakage of sulfuric acid corrosion of other equipment.
2. when you are on the water and find the battery is dead
(1) Disconnect the engine, when you find that the motor can not start you should first turn off the engine to prevent damage to the engine sudden start.
(2) Check the circuit, the engine can not start may also be a short circuit, check the temperature of the wire and resistance wire is disconnected to prevent accidents.
(3) check the battery ① power depletion if you can ship should be prepared to check the circuit equipment, you can also directly check the battery voltage to determine whether the battery contains electricity, for the dead battery should start the backup power to start the motor for its charging and so the battery is full before you can continue to use ② battery damage, battery damage to the battery should be replaced immediately with a backup battery. When there is no back-up power, call for support.
3. What should I do when my battery is completely depleted?
There are other ways to save your battery besides switching to a backup power source.
(1) Switch your battery to another boat. If there is another boat next to you, you can remove your battery and connect it to the other boat and borrow that boat’s battery to start the engine and wait until your battery has enough power before restarting your own boat to recharge the battery.
(2) Use a starter, in order to prevent the boat’s battery from running out of power the boat is usually equipped with a starter suitable for the engine, when used to connect to the engine can be directly start the motor.
(3) Remove the battery, the easiest way is to remove the battery directly and charge the battery separately before reinstalling it.
4. How to prevent the marine battery from dying?
(1) Connect solar panels, solar panels in the mooring will automatically charge the battery, the source of energy is sunlight is very convenient to use.
(2) Regular maintenance, marine batteries should be regularly maintained to ensure that the battery aging, battery breakage problems will not affect the use of the boat.
(3) When not in use for a long time, you should check whether all electrical appliances on board are closed to ensure that the battery will not be worn out all the time, in addition to charging the battery on a regular basis.
(4) Ensure the condition of the battery when preparing for a long distance trip, when you prepare for a long distance trip you should check the battery level, as well as make preparations for spare batteries and other rescue programs.
(5) Pay attention to trickle charging, battery charging when the battery will eventually go into trickle charging, the charging rate slows down do not unplug the power in time, keep charging for a while before unplugging the power.
Conclusion
When the battery is dead there is a big trouble for boat use, don’t panic when you find the battery is dead you should check the reason of the battery is dead and use other spare batteries on the boat, if you don’t know how to solve the problem you should ask for help from the rescuer in time, before using the boat on the overall state of the boat is an effective way to avoid it.
