How do you know when a wet cell battery has bit the dust? My depthfinder wouldnt work today other than GPS and my trolling motor was running real slow at all speeds. I finally saw a quick message on my depthfinder that said low voltage before going blank. I have an onboard charger and it does not give me any indication of a battery problem. matter of fact it shows fully charged batteries on both banks. the depth finder and trolling motor are on the same deep cycle battery. Thanks in advance for any advice.
