Check first: Hyundai hybrid battery warranty and bulletins
Hyundai hybrids use lithium batteries with a battery management system that behaves very differently from a Toyota NiMH pack. Many “bad battery” warnings turn out to be cheaper parts. Pick your model below.
Hyundai hybrid batteries at a glance
- Hyundai was one of the first brands to use lithium-ion polymer hybrid batteries, starting with the Sonata Hybrid.
- Hyundai hybrids use a battery management system, a safety plug fuse and a power relay assembly (PRA) that can trigger warnings even when the cells are healthy.
- Many Hyundai hybrids came with long battery coverage for original owners, so check your warranty by VIN first.
- When the cells really are weak or damaged, we explain repair, rebuild and replacement options with the test results in hand.

Hyundai Hybrid Warning Codes
Hyundai hybrids use their own codes: P1B70, P1B77, P1B25, P1B76 and P0A7F are the most common. See our Hyundai/Kia code guide.
How We Handle Hyundai Hybrids
We read the Hyundai-specific codes, check bulletins and campaigns, test the safety plug fuse, the PRA and the BMS data, and only then look at cell-level repair or a rebuild.
