    Ohmmu 12V Battery Feedback

    I noticed this as well. All research into the Ohmmu battery problems only seems to happen with Model 3 and Model Y cars after Tesla added some additional checks due to the horrible reliability of AGM batteries. Also, LFP batteries are more tolerant of charging at low temperatures. My experience...

    12v Battery life

    I'm sure it's at least that much for my 2013. It's really buried under everything and not easily accessible without disassembling a fair bit of stuff to get to it, and even then there's a lot of wiring that needs to be shoved out of the way. I was getting around 2 years of life out of the OEM...

    Ohmmu Model S lithium battery

    My first 12V battery died within a year. My second lasted a couple of years, and it seemed every two years I needed to replace the AGM battery on my 2013 Model S P85. Unfortunately, Tesla designed the Model S to make replacing the 12V battery a painful experience and made it very awkward to...

    Ohmmu 12V Battery Feedback

    I installed an Ohmmu battery in my 2013 Model S P85 a couple of years ago. So far I have not had a single issue with it. I'm guessing all of these issues are with the newer vehicles that have more advanced 12V battery charge controllers. I got sick and tired of replacing the AGM battery in my...

    CCS retrofit for 2013 Model S P85

    Doing some research it looks like there are some significant differences in communications between the Gen 1 and Gen 2 chargers. For example, it looks like the Gen 1 chargers drive the contactors directly and handle some of the communications. This is different than Gen 2. Sadly it looks like...

    CCS retrofit for 2013 Model S P85

    It's possible my car is compatible since I replaced the primary charger in my car with an eBay unit. After all that it turned out only a 50A fuse in the charger blew from old age (constant charging at 40A). I'm not sure what year the replacement charger is.

    CCS retrofit for 2013 Model S P85

    Yep. Tesla said it's available for 2014 and newer vehicles, but as far as I can tell there is little if any change between 2012-2014.

    DIY fixing a failed charger in a 2013 P85 and how to fix and prevent failure

    I should add that anyone doing this should be aware that high voltages could be involved and to use caution. If you aren't familiar with using a volt meter and don't know how to protect yourself from high voltage, don't do this. During the process of doing this I never once saw any voltage on...

    DIY fixing a failed charger in a 2013 P85 and how to fix and prevent failure

    I figure I might write this up to help anyone else who experiences this. First thing first, if you're regularly charging at 40A (or more), stop. If you don't need to charge this fast, back it off to 30A. The charger contains two 50A fuses and over time charging at 40A can cause them to fail...

    CCS retrofit for 2013 Model S P85

    I contacted Tesla about having CCS support installed in my 2013 P85 and was told that only 2014 and newer cars are supported. I went into the service mode, however, and the software implied it is supported and offered to reset the PLC gateway for it. Note that I have upgraded my center screen...

    My 2013 Model S needs new battery (I'm told)

    I didn't have any issues with the Fremont service center.

    My 2013 Model S needs new battery (I'm told)

    That seems in line with what I paid last year to replace the batter on my 2013, though I paid a bit less. After I had the battery installed I was told they should have charged a bit more for labor (they charged me $400). I paid out of pocket. My battery replacement fund (bought Tesla stock when...

    2013 Model S charge port pops open on its own

    On my 2013 Model S P85, I often close the charge port door only to have it pop back open a few seconds later. Once in a while, it seems to pop open all on its own long after it has been closed. Has anyone else experienced that? When it's locked it feels secure. Also, it looks like the LEDs...

    OEM CCS adapter now available to order in North America, Retrofit for older cars coming in 2023

    I was scheduled to retrofit my 2013 Model S but it was canceled. Apparently, the older cars are not supported yet and they were not clear about that. In the meantime, I have a Setec Power, now Lectron in the US, CCS to Tesla adapter. It works or at least did the last time I used it, but Tesla...

    Superchanging but not charging at home

    I had this same problem. It turned out that a fuse blew in the charger in my car, most likely age-related. Good as new now.
