Toyota Sienta Hybrid Battery Malaysia
Toyota Sienta Hybrid Battery guide and repair information for Malaysia owners.

Sienta NHP170 hybrid uses a NiMH hybrid battery pack under the rear seat. Malaysia's heat is the main enemy — the battery cooling fan must be kept clear. Battery lifespan: 150,000–200,000 km with correct care.
Hybrid Battery Care
- Clear the rear seat ventilation grille every service — lint and dust block battery cooling airflow
- Hybrid battery replacement new; remanufactured
- Avoid deep discharge: never let 12V flat — it prevents the hybrid system from starting
