No, according to the technical training manual on vehicle electronics, with standard anti-roll bars the auxiliary battery, in the engine compartment, is a 10ah lithium ion battery, but with active roll stabilization it's a 60ah AGM.
This does not affect charging, however, since charging is done not at the terminals of the main battery, at the back of the vehicle, but at the charging points in the engine compartment and the electrical system controls charging of the auxiliary battery via the power control unit at the rear right hand corner of the vehicle.
The main battery is AGM.
