solar chargers? VW OBD2 port chargers? OBD2 disconnect/reconnect cycles?

@cwerdna I have exactly the same requirements as you and I'm considering an obd solar charger. The only thing I need to double check is if the battery in my Prius is an AGM or lead-acid. It is not very easy to check as it is and I might have to remove some of the plastics covering it to see better.

Do you remember if the panels made a difference when you were using them?
