Hi all, sorry if this dummy question has been answered before.
I'm thinking of buying 2 new group 27 marine batteries, charge them up to 100% with a grid smart charger, then connect them in parallel and simply want to store the batteries indefinitely until needed for emergencies.
Not connecting to any solar anything unless ever need to one day.
How would I get the longest storage life out of them and how long until I'd need to replace them if never used?
Should I keep them on the smart charger positive to one battery negative to other battery all the time?
Or would weekly or bi weekly top up be ok?
Just thinking about the next ice storm extended power outages here in the great white north and would like some backup power for low powered medical device that can run on 12v dc or pure sine inverter. Don't want or need a generator.
Thanks
