Another battery charger question

Electrical dummy here:

I just bought a new Schumachher battery charger with all the whistles and bells, including a float charge capability.

My question: can two or more batteries be attached to the charger (in series or parallel, never can remember which is which) in the float charge mode? I'm thinking of pulling my lawnmower batteries and placing them on the shelf during the winter months with a maintainer attached. If possible, I would connect jumper cables between the battery connected to the charger and the second (and/or third) battery. Do-able?
 
Yes, you can parallel hook several batteries to a charger / maintainer.. Even the little batteryMINDer 12117 , rated at 1.5 amps is rated as able to maintain 4 batteries in parallel.
 
This one.

Read the manual,I doubt that it is rated as a maintainer. (I just bought a similar charger and the online posts and a message to the company said( Not for long term storage) Maintainers are $5.00 at HF.
 
I think you worry too much about batteries, Just make sure there is no drain, if suspicious unhook one cable, and leave them. Cold storage is better than too warm. I just replaced the battery in our JD 4600 yesterday, it lasted 12 years and 1 month! It sits in an unheated garage 2 miles from the CA border with no maintainer, and is not started for about 4 months in the winter. If you worry about your batteries move one maintainer to a different battery every month. Remember, a good battery won't freeze and if it's no good it doesn't matter! I don't want them to freeze and bust and leak acid so If questionable I may take them out over winter. Last winter I took the batteries out of the boat and put them in a big cooler siting on the garage floor.
