| Recently purchased a boat that came with a Galvanix Batt Cat 3-30 onboard battery charger (they are no longer in biz). It appears to have been factory installed with my Warrior boat (or at least it appears that way). It’s a 3 bank unit, one set of leads goes to my cranking battery and the other two for my 24v trolling system. The unit seems solid and everything appears to function properly (it has 3 LED lights on it that indicate which battery is getting charged and indicates when each batt is fully charged)… I just want to know for sure that it’s charging properly.
My question, is there any way to check the battery charger to see if it’s charging adequately? If I hook up a volt meter to the charger leads and plug it in what should it read? I’m no electrician by any means. I just want to make sure the charger is working properly and my batteries are getting fully charged.
What should at typ 12v battery fully charged read? 13.5v?
Thanks

| Most accurate way is to measure the specific garvity with a Hydrometer. Fully charged is 1.265. Notice open circuit voltage of a fully charged battery is 12.6
You can measure the open circuit voltagewhen the engine is off and no loads are connected. It can be approximately related to the charge of the battery by:
12.60 V 100% 1.265 g/cm3
12.35 V 75% 1.225 g/cm3
12.10 V 50% 1.190 g/cm3
11.95 V 25% 1.155 g/cm3
11.70 V DEAD
