hi there,
im cam, a licenced dignostic tech.
connecting chargers to the battery are always optimal, but if it is a low amp trickle charger than you will be fine through the cigarette lighter.
the 12v lighter plug must be a full time 12v outlet to be able to charge the battery directly.
if it is a ignigiton on or a accessory plug that only activated when isgnition is in on or acc position than it will not charge the battery.
