POSITIVE TERMINAL LOCATED ON RIGHT SIDENOTE: Requires SAE Terminal Adapter Kit - Part Number: 3217-0006 (SOLD SEPARATE)The Standard Original Equipment Lead Acid Batteries Are Heavy And Can Leak Acid. This Is Not What You Want, Especially If You Just Restored The Car! The MFI 911S - Using Stock Batteries - Can Experience Slow Startup - Surge/Hesitation At Cruising Speed - And Unbalanced Fuel Mixture. Why Odyssey? For Years We have Installed Odyssey Batteries In All Of Our Projects At Patrick Motorsports. The Advantages Are Crystal Clear: No More Leaks: Odyssey Batteries Are AGM (Absorbent Glass Mat) Dry Cell Type. They Have No Liquid Acid Inside - If You Cracked One Open Nothing Would Leak Out! Lightweight: Due To Having No Battery Acid Inside - They Are Considerably Lighter Than The Porsche Batteries. Faster - Reliable Startup: Cold Starts Are A Breeze With Odyssey Batteries - As They Operate At A Higher Power Level. Increased Ignition Output: This Is The #1 Reason To Upgrade. The MFI Porsches Especially Take Full Advantage Of The Higher Ignition Output - Resulting In Better Combustion - Smoother Performance - And Lower Emissions.
