We have a 2025 Lexus LX 700h Overtrail we plan to store for the winter and not drive. Should we have a battery tender? Which one is best? I don't know if a tender is best, a trickle charger, or nothing since it is a hybrid and has a very large battery with an auxiliary battery. And will the auxiliary battery if kept on a tender also charge the hybrid battery. I assume I should do something but not sure what. We could also start it periodically if that is the best approach. Thanks in advance.
