Hi Forum Peeps,
I need some advice regarding a battery problem on the new boat I have joined. There are 3 battery banks in the engine room one for each generator and main engine. The two for the Generators are maintenance free. The one for the main engine is lead acid battery. They are setup as two 12v in series to provide 24v………..
They are all linked to a Lewco Battery Charger.
The batteries are hooked up onto a monitoring system so that I can monitor the charge of the batteries at all time.
I found that the battery for the Main Engine is constantly sitting at 30v on my monitoring screen, whereas the other 2 batteries cycle from 27v to 30v as they are on charging cycle
I checked the battery compartment and felt for heat and there was none, I then checked the water levels and they were low and all cells on both batteries were low so I then proceeded to top them up, I still see no change……..after 2 days
I have attached a picture from the monitoring screen so u can see the trend…..
Why is this battery staying at 30v constanly,
Battery Info Nominal Voltage 12v Each
Cold Cranking Amps – 1100
Cranking Amps – 1230
Amp Hours – 200
Is this a problem? Should I replace the battery bank? Any further comments?
