      Interesting... it shows as active on my end but indeed it shows as expired on the website.

      Let me reach out to my rep.

        Apparently the codes expire, and then we have to renew them.

        NAM3FORUM should work tomorrow

                There are far cheaper alternatives to get a street safe lithium battery which is about 6kg.

                  Thanks for your input.

                  I've updated the OP with a temp code... they keep rejecting '9kracing', IDK why. Maybe I can only use codes once.

                      Thanks for the code, still trying to decide if its worth the high cost

                        There's a lot of factors that determine the value for someone.

                        Are you trying to lose weight?

                        Do you currently have an issue with your AGM battery?

                        Do you leave the car unattended for periods of a time?

                        Do lithium batteries make sense to you?



                        I personally run them in all my cars. I guess you could say I'm a convert. Anything that I can put in and then never have to think about again is worth it in my book. No maintenance, no trickle charger, no hassle. Just massive CCA on tap, 24/7

                        Plus losing 40 lbs is always nice.

                          The more I think about it, the more I agree with you. Not having to worry about replacing a battery or my wife ending up with a dead one makes a pretty strong case for going lithium.
                          That not having to deal with that stranded phone call is easily worth the cost
