Question for those of you with two batteries, I was out Friday night, playing music loud (one amplifier) and with all systems on but only refrigerator running.
We swam for maybe 2-3 hours tops, and everything fired up as normal, started underway at idle in shallow water, then both alarms kicked in, and the battery dropped to 8V from 10/11 with alarms. Switched the battery switch to both and everything was fine. Got boat on plane, and switched back to battery 1 to fully recharge it.
Now this happened last summer a few times, so I replaced the batteries due to the old ones being 6-7 years old.
Granted we typically do the same thing for a longer period of time, and typically dont have this problem, and havent this season until now.
I am running two 1 season old Interstate Deep Cycle batteries. I try to treat battery 2 as an emergency only battery.
Does anyone else run into this? Does anyone think that the battery could be failing?
