Trickle charging

I want to hook up my 2014 International batteries to a trickle charger. Do I need two or one charger when the batteries are in the trailer?

Are they wired together? are they already charged? I have found trickle chargers can handle more than one battery but they have to be mostly charged before expecting a small trickle charger to be able to put in enough charge.

Trickle Charging

Actually my main concern was whether I would "cook" the batteries if I attached one trickle charger to each battery while they are installed in parallel (if that's the right term).

I would recommend against traditional "trickle" charger use for any extended time period. Something like a "Battery Tender" brand smart type is fine if it is designed for the battery type you are using. The difference is that it incorporates a multi stage charge regime that will allow the batteries to float when finished charging. This prevents the overcharging that "cooks" the battery...

These: http://www.amazon.com/BatteryMINDer-...er+model+12248 are great for any type of battery maintenance charging.

Lewster, looks like a great unit. So this would be a good charger hooked up to the standard Airstream (two 12v deep cycle) tongue battery box? I have a FC25 on order so not sure about the room in the box. Could this be mounted inside the box? Would be charging while parked at my home and also when camping with port. generator. Do you connect the charger to a positive terminal on one battery and the negative terminal on the other battery, or positive and negative to the same battery? Thanks for your help and hope to visit you at some point for a solar upgrade.

It's a great unit but is not a rapid charger as it is only a max. of 8 amps. Works well if you have time to charge the batteries.

You are correct about connecting to the positive terminal if #1 and the negative of #2.

Another option is to replace the Airstream stock Parallax converter with something like below and trickle charge your batteries directly off your trailer. Then one less thing to haul around.
