    Hi, I missed the labor day sale this past weekend. Any chance I can still get the 15% discount on a new battery for my 944T? Probably the difference between buying one now and waiting for the next sale...

    Thanks!

    I’m looking to get the 30” battery lead set when they’re available what Micro Start would you recommend for this application.

    Hoping for for a quick response as I’d like to take advantage of the Black Friday sale.

    Thanks.

    Hi. I'm interested in the jump start product. We currently use the Ctek systems and have their cable connected to the battery and the connector accessible with the frunk closed but this is primarily a trickle charger and if we screw up we need a power supply and it takes a while to boost the car. As you know, when the battery dies on many of the newer Porches the door and frunk can not be opened without removing the wheel well to access the emergency cable. Does your jump start system offer cables that can be run from the battery out the lip of the frunk for a boost when the car battery dies without having to open the car? How many jump starts before the jump starter needs to be recharged and how long does it take to recharge?

    Thanks for taking the time to respond. Please reply by email to me at hirschcars@gmail.com .

    Thanks

    Ben

    Also , can the battery ship oversea by Air ?

    Thank you

    Hello
    Please PM me the price for the three options.
    Do I need to have the tray to mount the Li battery or will the original mount work?
    Thanks

    Hi Scott,

    several users of the Audi R8 Forum www.R8talk.com would love to join the group buy here too. We have a 30kg brick=lead acid battery upfront, so even more weight savings then in a 911 :-)
    here is the thread:

    Thanks

    Hello,

    I have a 2RS coming in October, would the RS30 also be the best option for me?

    Thanks

    I am interested in your 3 option costs. Based on what I read, this battery should also work on 2013 991.1 C2S. Thanks.
