What type of battery is in the 2016 Lexus RX 450h?

Hybrid configuration: the vehicle uses a high-voltage hybrid battery pack designed specifically for the hybrid system, paired with a conventional 12V auxiliary battery that supports electronics and start-up systems.
Chemistry and design: the high-voltage pack is a manufacturer-specified hybrid module optimized for longevity and safety; chemistry varies by production run and option packages—our technicians verify the exact spec for your vehicle.
OEM specification: Nalley Lexus Smyrna installs OEM or manufacturer-approved battery modules to ensure compatibility with vehicle systems, performance, and warranty requirements.
Diagnostics first: we always perform a complete battery health assessment to determine whether the issue is the high-voltage pack, the 12V battery, or related charging components before recommending replacement.
Warranty repairs: any battery repairs covered by warranty must be performed at a certified dealership to maintain coverage and to ensure installation by factory-trained technicians using genuine parts.

What size battery is in the 2016 Lexus RX 450h?
