Charging boat battery while connected. Chargers will often briefly finish a charging stage applying a higher than normal battery charging voltage. Some can reach fifteen to sixteen possibly damaging volts. Whether a pulse charger or a more traditional charger with a high charging voltage is safe connected emm may depend largely if the engine is being at times powered ON while its connected battery is under direct charge.
Charging battery while its in the boat. A couple of points just to be clear. Use a charger that is designed to be hooked up and left.
Not all chargers are made to leave on a battery indefinitely. I am a little wary of leaving even small trickle chargers on for extended periods. Make sure that the gases produced while charging can vent.
Charger is connected to the batteries all the time and plugged in all the time while the boat sits on its trailer. If your batteries are regular flooded cells they should be in an area where theres adequate ventilation while charging. But I see no need to disconnect the cables.
If youre able to open the battery compartment then keeping it open during charging should be adequate. If you choose to store your boat outdoors at a marina some marinas might not allow you to connect your battery to a trickle charge. In fact in some incidences this might even void your boat insurance.
Although the winter months typically have less sunshine you could look at using a solar panel to help keep the charge in the battery. You can get around the problem by using a battery-sensed alternator which will do a much more efficient job and enable the batteries to charge fully. Its also advisable to fit a switch so you can combine the batteries in an emergency they will otherwise be completely separated and you wont be able to start the engine using the house battery.
With the circuit connected via the multi pin plugs in the boat I can now charge both batteries charge one or the other isolate out the charger and test voltage on both batteries or individually. All from the charging station and without having to. How To Charge A Boat Battery On The Water.

It helps to extend the life of your battery and make it more reliable. Marine battery chargers are between 10 and 15 amps. In order to get a quick charge a charger that delivers more amps is required.
So the same wires will provide power to the DC circuits when shore power is disconnected and receive power from the converter to charge the battery while connected to shore power. That also explains why the DC circuits still operate when the battery disconnect switch is set to off - the converter is powering the fuse panel for the DC circuits. The absorption stage is where the voltage is now constant but the amperage is tapered and regulated while the battery is topped off.
This constitutes roughly the remaining 20-25 of the charge and the battery should now register anywhere from 141 volts to 148 volts. Depending on something called a set point in the charger the current must be varied in a precise way in order to hold the voltage constant. You dont want to directly connect the batteries together unless you use wires that can handle the starting current of the truck and you dont want the boat to discharge the truck battery while the truck is not running.
Running your boat battery below 50 state of charge is really bad for it. Begingroup A real-world example of a charging source delivering less current than the load sometimes requires. An iPhone and I bet many other smartphones.

Identify the positive and negative battery postWarning. If you are unfamiliar with these. There are two main approaches to charging up a deep cycle battery.
The first is to charge the battery while its on the boat already in the fixed position. The second is to take the battery out of the boat and make use of a portable charging unit to top the battery up to full. The car battery must not go through any disconnection made when fully charged itself.
The marine batterys charging procedure will be controlled by the alternator of the idling engine. Nonetheless a 12-volt batteries hook simply up to an alternator. If you have a trolling motor then the battery charger is a must.
If you dont have a trolling motor and are only running 1 or 2 things on the boat then you can probably get away with not having a battery charger. Also utilizing a battery switch that allows you to turn off. Battery charger before each use of the boat to maintain optimum performance and life of the battery stator and regulator.
If multiple accessories are used a 2nd battery NOT connected to the starting battery is recommended. If desired a make-before-break switch can be used between the two batteries. Make sure to also charge this battery off.
