12v battery replacement


    12V Backup Battery

    Here is one for the 12V battery gurus out there. What if a lead is run from the battery to the frunk storage area, like for those who connect a battery tender for long term storage. But in this case in the event of a 12V battery problem, could we connect a second 12V battery to the lead and...

    12v Battery - Using LiFePO4

    My choice for battery three years ago was the Bioenno BLF-1250AS, LiFePO4 (Lithium-Iron).

    Today my beloved 2014 Tesla P85 with 13,800 miles on it stranded me at the Savannah airport SC station. Fortunately I was there near rental cars and not on the vastly empty I 16 headed to Atlanta. The roadside assistant was very helpful and got a tow truck there quickly but Tesla's policy is to...

    Tesla great service changing? Have to take car in for warranty fix.... no valet...

    Hi, I'm just wondering if others have been told their Tesla service center is "low on manpower" and so they must bring their car in to have warranty work done and wait for it? This reminds me of my Chevy dealer - and I'm not too happy. I got home this weekend after being out of town for 3...
