  • MSRP $217.11 $189.00

  • Region:
    Add Adapter Clamps (Recommended):

Charger and trickle charger (5.0 A). The increased charging power reduces the battery's charging time. Select your region.  An additional charge mode for Porsche lightweight batteries (lithium-ion) facilitates their use in motor sports, ideal for GT3, GT3 RS, GT2 RS, & other models with factory race batteries.  This battery maintainer won't fix a defective battery. If you suspect that the battery is defective, or if a maintainer won't help, have your battery tested by a professional.


  • All Boxster Models - 1997-2024
  • All Cayman Models - 2005-2024
  • All Carrera Models - 1999-2024*
  • All Cayenne Models (except Hybrid) - 2003-2024*
  • All Panamera Models (except Hybrid) - 2009-204*
  • All Macan Models** - 2014-2024*         
  • Classic models*

  • NOTE: "*" Battery Clamp Option:  Some Classic and newer Porsche models won't allow you to charge via the cigarette lighter socket.  For these models, you have to add adapter clamps so you can charge on the battery terminals directly.  We recommend adding these clamps to make this maintainer compatible with a wider range of vehicles.  See our notes below about vehicle specific restrictions and fitment.


    Vehicle Specific Notes (updated):

    • 981, 991, & 718 -  For 2013-2024 Boxster or Cayman, & 2013-2019 911 Carrera models:  Long term storage can put these cars in "Sleep Mode", which will disable the center console plug socket and shut off the battery maintainer.  To bypass this, lock the door after setting up the battery maintainer.  Or directly connect the battery maintainer to the recommended charging points using the optional alligator clips.
    • Macan -  "**" Macan models can't be charged at the 12 volt plugs inside the car. To bypass this, visit your local Porsche dealer and they can code your Macan to accept a battery maintainer. Or purchase the additional battery clamps and charge the battery directly.
    • Panamera - For 2017 or newer Panamera models, you must purchase the additional maintainer clamps and charge and the battery directly.
    • Cayenne - For 2017 or newer Cayenne models, you must purchase the additional maintainer clamps and charge and the battery directly for models without a cigarette lighter. 
    • 992 - For 2020 or newer 911 models, you must purchase the additional maintainer clamps and charge at the battery directly.
    • E-Hybrid Models - This is NOT compatible with Porsche electric or hybrid models.
    • All Models - In the event of a power outage, the maintainer will not restart itself automatically (for safety purposes).  If power is lost, you will have to manually restart the maintainer when power is restored.

    Good quality

    This is my second Porsche battery maintainer. My first one was purchased 15 years ago. I think they deserve a second shot at my business.
    Simple to use

    Works right out of the box, plugging into the 12 volt vehicle outlet makes it so easy to connect. As soon as you connect, select the battery type, and the unit will tell you the current charge status. Connect the unit to the 12 volt outlet in the vehicle first and then plug into the electrical outlet. Do the reverse when you disconnect

    Outstanding product. Very useful features and easy to use. Have used other brands on previously owned vehicles but this surpassed all of them. Highly recommend this unit .
    For hibernation
    (California) | February 13th, 2020
    Purchased this for the occasional use on my 992. I rarely put her into hibernation, but if I do, I use the connection under the passenger footwell. Still trying to figure out how to keep it on after a week or two, the car will go into a sleep mode and it turns off the unit. So there has to be a workaround, but I am still trying to figure it out.

    I needed a maintainer for long term storage. I have used this twice and left the car for 6 months at a time with no issues. I did not want a charger that would over charge the battery as I have had problems in the past. This works well and plugs into the passenger side under dash port.
