Description
The Antigravity H6 / Group-48 RE-START Lithium Car Battery is a direct, OEM-size replacement that cuts up to 70% of your battery's weight while delivering far more cranking power than the lead-acid unit it replaces. The H6 is one of the three most common performance-car sizes on the road, fitting a huge range of European and high-performance vehicles — Porsche, BMW, Audi, Mercedes-AMG, Lamborghini, Ferrari and more.
The headline feature is RE-START technology. An intelligent on-board Battery Management System (BMS) constantly monitors the battery, and if it ever senses over-discharge — say you left the lights on — it puts itself to sleep while reserving just enough energy to start your car. Press the included wireless key-fob (or the button on top of the battery), start the engine and drive away. No jump pack, no roadside call, no opening the hood.
Key features
- Wireless RE-START built-in jump-starting — you'll never be stranded by a discharged battery again
- Full Battery Management System — over-charge, over-discharge, short-circuit and thermal protection, plus cell balancing
- Up to 70% lighter than lead-acid — roughly 25–55 lb of instant weight loss for sharper handling, braking and acceleration
- Exact OEM drop-in fit — no trays, spacers or modifications required
- 2–3× the lifecycle of lead-acid, with a 7–9 year expected service life
- Lithium-Ion chemistry — no acid, no lead, vibration-resistant and spill-proof
