Did I kill my house bank? Electrolyte was low.

6 years for FLA is great life span! Do the sage and safe thing. Replace them or get really good boat insurance and replace the boat when it burns to the water line. REPLACE THEM....NOW.......PLEASE.

6 yrs is a good run. Get new bats.

Check with a hydrometer, are all the cells equally charged?

Buy a load tester and see if the batteries hold the charge or not.
My Trojan 105s last about 6 years.
I check the electrolyte levels once a month.
Hard to say if your batteries are ok or not by posting an opinion.
How old are your batteries? What brand?
What kind of charger?
Anyway, if in doubt replace them.
