We are trying to leave the
dock and go to the
Bahamas for a month or so.
I have 12 6-volt Trojan T-105 Lead Acid
batteries. They are about 3 1/2 years old now. I've only owned the
boat for the last 1 year 1/2, attached to a
dock all except a 45 day trip to the
Bahamas last year.
Prior to my
ownership, the
boat was
on the hard and went threw
Hurricane Matthew in a boat yard with questionable
power. So the
batteries have unknown abuse prior to my
ownership.
I've equalized twice within the past month. Hyrdometer is coming back in the green.
My
battery tests at the dock are not going well. I'm dropping to 12.5 volts within 3 hours of disconnecting
shore power, with very small draws going on. My
laptop is plugged in to AC, and my AC fridge kicks off every once in a while drawing 10 amps DC.
Time to replace? Anything else I can do to test? I have access to a load tester, but I'm not sure it would do much. I know these batteries are getting older, but they don't have alot of cycles on them.
Thanks,
