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