The 911 GT3 Cup (991) has been significantly improved in terms of operating
comfort and functionality. Compared to previous models, the electrical equipment
has been upgraded and new and attractive features are available. The integration of

Battery
An AGM battery (Absorbent Glass Material) with 80Ah is used in the 911 GT3 Cup
(991) (6.2.1.1). Special micro-fiber glass mats are inserted tightly between the
positive and negative lead plates, binding the entire battery acid. In demanding
situations, higher amounts of energy can be delivered by the fast reaction between
the acid and the plate material. The battery is maintenance-free and sealed. To
optimize the vehicle’s weight distribution, the battery is installed inside the vehicle in
the passenger foot well.
The maintenance-free AGM battery offers the following advantages:
•
Sealed, valve-controlled battery with high cycle stability
•
High cold start performance
•
No acid leaks in case of damage, vibration-, leak- and tilt-proof
•
Flexible installation and safe handling
•
High capacity and longer service life

amps.
The battery is designed for a cut-off
voltage of 14.5 to 14.8 V
The generator cut-off voltage is 13.8 V
