Thank you very much for this video that was very helpful. I have a 2023 Highlander hybrid that I inadvertently left on without my key and went in somewhere for about an hour and a half 90 minutes and when I came out it was totally dead check engine light I could not start it however waiting like 20 minutes. It did finally start for me but I’m worried about the battery now and wonder if I should have one of these in stock on a tender possibly just so that I’m Ready? These little 12v batteries I’m assuming are more prone to expiring sooner then there larger counterparts? AND especially if fully discharged as described earlier wondering if damage could have occurred and thus shortened its future life? Your thoughts/knowledge would be appreciated. Thanks in advance.
Also that USB charger cord? Ultimately a meter? You have plugged into 12v dash access…where is the other end of the wire going?I currently have a dash cam plugged into that right now though.
