If you already know what you drive, go straight to your model. The symptoms that show up first, how the pack is packaged, and what tends to fail differ enough between them to be worth reading before you call.

• Pack voltage and module count vary with vehicle size — a Highlander Hybrid pack is a different animal from a Corolla Hybrid pack.
• Pack location varies: behind the rear seat, under the rear seat, in the trunk, or under the second-row floor depending on the model and generation.
• Cooling intake location varies, which changes what blocks airflow in real life. In a three-row SUV that's often cargo and car seats; in a sedan it's usually the trunk or rear parcel area.
• Newer models increasingly use lithium-ion rather than nickel-metal hydride, sometimes varying by trim within the same model year. That changes both the part and the appropriate service approach.
• Access labour varies enormously. Some packs come out in a straightforward afternoon; others need a lot of interior disassembly first.

Every Toyota hybrid pack in the Valley lives a harder life than the same car in San Diego. Sustained heat is the main driver of pack ageing, and a car that spends summer parked on asphalt in direct sun soaks it up.

• Cabin-air cooling means the pack's cooling air is only as good as your cabin air and your intake vent.
• SUVs and minivans get their intake blocked more often than sedans, because owners load cargo against it without knowing it's there.
• Cars that sit for long periods in summer heat — a second vehicle, a snowbird's car — see their own kind of stress.
• Covered parking genuinely helps. It's the single easiest thing an owner can do.
