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.
 
I would recommend using a smart battery maintainer (often called a "battery tender") connected to the 12V auxiliary battery. This is the most reliable, hands-off approach for multi-month storage without driving. The HV battery self-discharges very slowly and has built-in management, but it benefits indirectly from a healthy 12V system. Many Lexus/Toyota hybrid owners and guidelines favor a maintainer for storage longer than a month to prevent issues. I have had good luck with CTEK battery maintainers. I've linked one of their products below.
