Getting ready for winter storage

[Speedy]

I am sure many of you have multiple batteries on board. I have a 12 volt for the main engine/outboard and also two 12 volts wired to make 24 volt for my electric motor. Do any of you use those "Mini" chargers/battery keepers? If so, leave one on each battery? My boat is in a dry un-heated garage with power. All batteries are disconnected for the winter. Thanks for your advice.
