Can a battery isolator drain a battery?
With an isolator, no battery will drain the other batteries in the system, enabling redundancy for a system with multiple auxiliary batteries plus the main battery on a single alternator. On the other hand, a larger alternator may be needed since an isolator will charge all batteries evenly.
Does a battery isolator charge the battery?
A battery isolator can eliminate the problem of battery drain all together. The isolator's role is to allow the alternator to assist with charging the primary battery, while at the same time not allowing other loads in the charging system to drain the primary battery.

Most vehicle alternators will never properly and fully charge up a Deep Cycle battery so invest in a good charger or a solar arrangement with a charge controller/regulator with at least a three stage charging control (many chargers are now 6 or 7 stage affairs).
Can I trickle charge two batteries at once?
An example method of charging batteries in parallel is to use one branch of the parallel circuit to charge each battery with a single charger. Connect the positive output of the charger to the positive terminal of the first battery, and connect that positive terminal to the positive terminal of the second battery.
