I have three bikes that will need some sort of battery maintenance through winter. The bikes are in a car park with no access to mains. Is the optimate suitable for battery maintenance at home? How do they work? Do I just plug it in and attach it to each battery at a time for a certain amount of time on a regular basis?

I've never used one of these so any info would be appreciated. I've checked their site and that mainly refers to plugging into the mains and allowing to sit over lengthy periods...rather than having three batteries out of the bikes at home.

For info, one battery is completely flat, the other two are relatively new.

Thanks
Den
