This reminded me to charge up my utility 12V's. They were sitting next to the pump where they were last used.
As Proxim states, a battery that isn't charged or left in a discharged state will start to sulfate immediately. Best scenario is to keep some voltage on them continually. I now have a 12V bench supply with Open Circuit voltage of 15.5 VDC connected to one battery. The voltage at the terminals is 12.7 V. I will watch the voltage over the next few days as it rises and will remove charge at 14 V or so. That will give the battery a full charge and be ready for another use.
