Deep cycle batteries are also great if you need to power a depth finder live well bilge pump gps fish.
Add water to deep cycle marine battery.
Deep cycle marine batteries require regular maintenance and depending on the type of battery you choose you will need to do different things.
If it isn t you need to add water to the cell.
After charging add enough water to bring the level to the bottom of the vent about below the top of the cell.
Functionally there are two or three different types of batteries that you ll encounter at your marine dealer.
Deep cycle a deep cycle battery offers a lower and more steady rate of energy than the cranking battery.
Look for a small square lead plate in each cell of your battery.
It s important to note that battery owners should never add sulfuric acid to their battery.
Examine the battery for current water levels.
But a car battery can only handle a 20 discharge.
Checking the spg without charging first will give a false low reading as the water will be at the top of the cell and will register as being low when checked with a hydrometer.
What is a deep cycle battery and how do i choose one.
Charge the battery and allow it to rest if you plan to check the specific gravity spg of the battery after adding water.
How to charge a deep cycle battery properly there are two methods.
Fill it to just above the plates if the level is below that.
During normal operation batteries will only consume water and not sulfuric acid.
This means that you can run all of your electrical equipment without the risk of having to charge your battery on the water.
For example if you decide on a flooded battery you will need to provide distilled water every time you refill it.
Deep cycle marine batteries can sustain up to 80 discharge and still be recharged again and again.
To make sure that your deep cycle battery is charged fully you need to use a hydrometer to determine the specific gravity.
One is to charge the deep cycle marine battery in place and the second is to remove the battery from your boat and use a portable charger that you connect directly to the deep.
Refill the electrolyte level by removing the vent caps and using mineral free water distilled works best.
Starting batteries are designed to deliver a short burst of high current and to not be discharged to a.
After removing the port caps of your battery you put the tube of the hydrometer into the electrolyte then squeeze the black ball.
After that gradually release and liquid will flood the window.
When your battery s electrolyte is observed to be low filling the battery with water will keep the battery healthy and safe for use.
Fill a charged battery up to 1 8 inch below the fill well.
Then don t add any more water until the battery is charged.
The charging process will mix the new water into the old electrolyte and give an accurate spg reading.
