hard to say, all depends on temps and # of starts since they quite holding a charge. I would not want to try more than a day myself.

Check your battery connections and make sure they are tight. Ran into the same issue, and it seemed to fix it.

It could also be that one of the alternators is bad as well. I believe that the battery light is not only for the batteries but the charging system as well. Good luck.
