If they are 6v, yes, connect them in series to charge/maintain them as 12v
If they are 12v, they must connect in parallel to charge as 12v.

Yes

I use the Deltran Jr Maintainer to keep the batts happy on the Z Turn and Lawn Tractor thru the winter. Made a jumper to hook the two batts together in parallel.

It works great. The things crank like new in the spring.

Did you ever read The 12 Volt Side of Life?

It contains very useful info on batteries.
