It looks like I’m going to need to replace my start battery bank. These were replaced by the previous owner as part of a major electrical upgrade (new alternators, Balmar regulators and centerfielder and all new batteries) in 2016, which makes them 8 years old.
The engines have always started just fine, but lately I’ve started getting low voltage alerts on starting, and the windlass, which is also powered off the start bank (?) recently overheated and popped the breaker after drawing the voltage down to 11.4 while raising the anchor.
The existing start bank is two Lifeline GPL-8DL deep cycle batteries. I would just replace them with the same batteries but I have always understood deep cycle batteries are not best for start batteries, PO had a marine electrician do all the upgrades, so I would think there is a reason an “expert” picked these batteries.
Does anyone have suggestions about whether to just replace these with the same batteries or switch to something other than a deep cycle battery?
