Lexus GS 450h hybrid battery questions

Can a Lexus GS 450h hybrid battery be repaired instead of replaced?

Often, yes. It's a nickel-metal hydride pack built from forty modules, so if the weakness is concentrated we can replace the weak ones. The module test data decides it — not the trouble code.

Is the GS 450h pack the same as a Highlander Hybrid pack?

They use the same module and the same 288V, 40-module design, which is why the module is easy to source. The assemblies and part numbers are model-specific, so we confirm against your VIN.

How much does a GS 450h hybrid battery cost?
