Greetings All,
I will store my boat with 10 supercycle agms for appx. 7 months. I have solar/mppt, a skylla-I charger and access to shore power. What is the best and safest way to store my batteries? Charge and let them sit? Trickle solar? Trickle charger? I want to keep them for a long time. Thanks for your time.
When I store my boat for winter season I usually charge the batteries full when on shore. I leave all connections and cables as they are and top up the batteries once a month since I have the possibility to do so since I go to the boat every now and then to get some improvements done.
Without any major things connected I still have a draw of about 1 A (meters, regulators etc) which I balance with this top up. Since I live in the cold North (Sweden) I could disconnect all cables from batteries and do without any top-ups during winter season - if I would't be there at all. The self discharge is lower in cold weather.
As you have solar, leave it on. Sure, disconnect loads, but keeping solar on to balance self discharge is good.
