Conditioning batteries?

[Jdege]

So, I was at my boat, today.

It's sitting in a boatyard, waiting for spring.

I wanted to check on the tarp, see if the guys who'd winterized the engine had put everything away correctly, and I wanted to pack up the sails and cushions and bring them home, so I could store them someplace dry.

And while I was there I got to talking to one of the old guys and he said he always removed his lead-acid batteries and kept them on a battery conditioner, over the winter.

I have lead-acid batteries myself, one 12v starter battery and four 12v batteries for the house bank.

So I'm wondering if it's a good idea. Anyone have any opinions?

Any sources of information?

Lead acid batteries and for that matter any battery needs to b on a trickle charger if left for any time in a no use situation. Much better if u can take them out and put them in a heated environment. I have learned this from my aviation experience for over 50 years.

Here’s a white paper from Trojan on LA battery storage. And a bit more from Trojan.

The biggest point; make sure batteries are at 100% SoC before storage, and don’t let them drop below 70% (remember, LA can self-discharge at 3-5%/month at winter temperatures).

Actually not correct as a blanket statement.
Fla yes but lifepo4 definately not they prefer to be stored between 30 and 60 % . Keeping them on a trickle charger will kill them as upposed to saving a flooded lead acid.
Must make that distinction.

Sweet!!! How do I switch to LifePo4??? I have two (2) Lifeline GPL-27T batteries and wouldn't mind switching to LifePo4 since I've been hearing sooooo many good things about them
