Coach & Powertrain: Battery Storage During Winter

I live in Canada. Typically I remove the two 6-volt batteries from the coach and store them in an unheated garage. I would like to keep the batteries charged during the winter period. Could you recommend a charger that will suit my needs? Also is it possible to charge both batteries at the same time?

Yes, use a maintenance charger such as a 12-volt Battery Tender (available from Camping World and other RV stores) and charge them in series. This will require that you use a jumper wire running from one positive (+) terminal to the other battery’s negative (-) terminal. Then connect the other terminals to the battery charger.
