The Antigravity ATX-30 RE-START lithium battery is very compact, with a much smaller footprint than the original H6/Group-48 lead/acid battery found in your Porsche (or other Hi-Performance Car). But with this Mounting Tray securing the ATX-30, it then directly swaps into any Porsche that uses the “H6” aka “Group 48” size with no need for modifications. This makes the ATX-30 a quick and relatively painless battery swap most anyone can do.
This ATX-30-RS Mounting Kit uses the same stock mounting cleats as your 991.1 or 991.2 or any car using the Group 48/H6 size Battery including GT4s, Boxsters as well as most all other vehicles that use that battery size. Secured within its mounting tray, the ATX-30 becomes a direct swap for the H6/Group 48 battery.
The mounting tray is a CNC’d Aluminum design available in Billet raw Aluminum. The kit also includes a matching Top Bar, two Support posts, adhesive-backed foam pads and hardware.
But it should also be noted that the ATX-30 can potentially be TALLER that some stock batteries listed below due to the necessity of adding our SAE Car Terminal Adapters to the ATX30 to accept Automotive Style Battery Cables. So please check your measurements before purchase. The Automotive SAE Terminal Adapters add 1″ to the height of the ATX30, which alone is 6.5 x 5 x 6.89 inches LxWxH (mm: 165 x 127 x 175).
