Default Battery Storage

So I'm looking to store three brand new batteries for the winter. I need new batteries next year and got a killer deal on these. I'd like to use my current one thru the winter months. Any issue with leaving the new batteries in my house (not on a charger) till April? I have to assume batteries have been kept on store shelves just as long.

The are flooded group 27's.

They will be totally fine. Especially in controlled environment. Only downside is losing out on the warranty

I keep mine on my wooden workbench out in the garage. I charge them every few weeks over the winter. Been doing it like this for years, no problems.

I store my boat batteries in the garage over the winter. I have them sitting on 2x4’s, and usually wait until a week before I re-install them to plug in the charger/maintainer for a day or two. My garage is attached, so it rarely gets below freezing, but I have never had an issue with leaving the batteries as long as 4 months. I am reluctant to leave them on the maintainer long term just in case of a charger malfunction, however unlikely.

I encourage you to google marine battery maintenance and then make your decision when you are well informed.

Store them wherever you want
But but... Keep them charged.
Batteries will self-discharge over time. Even weeks.

Id check them at least once a month, and top charge off.
Sometimes some don't like to come back fully if they spend time in the depleted state

easy way is to hook them up in parallel and use a trickle charger and put a plug in wall timer in on the plugin to turn on for ten minutes a day. then they wont over charge and stay topped off.


or go charge them every couple of weeks.

Thanks all..my main concern was having them sit for four months and discharge them to a point where I couldnt get them back.

Charge them well before storing and keep them warm and they'll be fine.
