Gday all,

Anyone please..
Can I charge my auxiliary battery (Optima Y. Top) with an external ac-dc charger (Bosch C7) while the battery is still connected to the in-vehicle battery charger (Redarc BCDC1225)..? She is not my daily and since my Safari is on a 24v system, all 12v accessories including a dvd player and the alarm system are running out from the aux battery. I have the Bosch charger so was thinking to make use of it while the Safari parked in the garage for a week or sometimes longer. I've asked Redarc but just couldn't wait till they reply my email.
