Is the battery charger automatic?
A. Yes. It senses when the battery has lost any of it’s capacity and recharges the battery until it reaches a fully charged condition. If the charger senses that the battery has decayed to a level below 10 volts, it will determine that the battery cannot be trickle-charged and will not go on. At that point, a high capacity charger must be used or it may be time to replace the battery.
