A hybrid system warning light.

Repair or replace

A few weak modules with the rest grouped tightly: module-level repair.

Toyota Avalon hybrid battery questions

Is the Avalon Hybrid battery the same as a Camry Hybrid?

Closely related for the same era, but the pack assembly and part numbers are model-specific. We verify against the VIN before ordering anything.

My Avalon sits for months while I'm out of state. Does that hurt the battery?

Sitting in summer heat is hard on a hybrid pack and harder still on the 12V battery. If your car sits for months, have both checked before you start driving it again.
