Drain on batteries while on shore power.

If I use 12V lights (drawing a couple of amps) while connected to shore power and my (smart) battery charger, does it shorten the life of my batteries, or simply use them as a conduit?
Edit: Accidently posted this thread twice ("Using 12v while on shore power"). Maybe moderators would delete one and combine the the responses? Thanks

Re: Drain on batteries while on shore power.

The power is "pass through" until such time as your consumption exceeds the charging capacity of your smart charger, then the batteries will supply the missing power and get drained, at least until your consumption goes down and the charger can catch up.
