The answer depends on the model. A standard non-hybrid Honda Jazz uses a 12‑volt lead‑acid battery, while the hybrid Jazz e:HEV relies on a high‑voltage traction battery for propulsion and also has a separate 12‑volt battery for electronics.
Across generations, the specifics have varied by market and year. Early Jazz hybrids used nickel‑metal hydride (NiMH) packs, while later hybrids have employed lithium‑ion (Li‑ion) packs in many markets. The exact chemistry and capacity of the high‑voltage battery, as well as the size and type of the 12‑V battery, can differ, so always check your owner’s manual or with a Honda dealer for your exact car's specification.
Non-hybrid Honda Jazz: 12V starting battery
Here is what you typically need to know for the standard Jazz models that run on petrol/diesel and do not use hybrid propulsion.
- Type: 12-volt lead-acid battery (most are maintenance-free; some markets use an AGM variant).
- Typical capacity: roughly 40–60 Ah, depending on market and trim.
- Installation and replacement: fits in a standard battery tray; verify the OEM part number or group size for your exact model.
- Replacement tips: ensure adequate cold-cranking amps (CCA) for your climate and follow proper safety precautions when handling the battery.
In practice, you’ll replace the 12V battery with a like-for-like 12V lead-acid unit that fits the Jazz’ battery compartment and matches the car's electrical demands. Always verify the size and rating from the owner's manual or dealer before purchasing.
Hybrid Honda Jazz (Jazz e:HEV): high-voltage battery and 12V system
In the hybrid version, propulsion relies on a high‑voltage battery to power the electric motors, in addition to a conventional 12‑volt battery for electronics.
Battery chemistry and capacity by generation
Older Jazz hybrids used nickel‑metal hydride (NiMH) packs, while newer models in many markets employ lithium‑ion (Li‑ion) traction batteries. The high‑voltage pack is typically around 1.0–1.5 kWh of usable energy, with exact figures varying by year and market. The high-voltage battery is a sealed, high‑voltage system that is not user-serviceable in the same way as a 12‑V battery. A separate 12‑V battery powers conventional accessories and electronics, similar to non-hybrid cars.
- High-voltage battery: NiMH (older hybrids) or Li‑ion (newer hybrids) depending on market and year.
- Capacity: approximately 1.0–1.5 kWh of usable energy for the hybrid drive system; exact spec varies by generation.
- Location and integration: mounted as part of the hybrid drivetrain pack, with packaging that may place components under seats or in the rear area depending on design.
- 12V system: a separate lead‑acid (often maintenance-free or AGM) battery powers normal electricals and accessories.
Because high‑voltage battery specs differ by year and market, consult the owner’s manual or Honda dealership to confirm the exact battery chemistry, capacity, and replacement procedure for your Jazz e:HEV.
Summary
The Honda Jazz can have two distinct battery setups: a conventional 12‑V lead‑acid battery for non-hybrid models, and a hybrid system with a high‑voltage traction battery (NiMH or Li‑ion) plus a separate 12‑V battery for electronics. If you’re replacing or servicing a battery, identify your exact model year and market to obtain the correct part and specifications from the manual or a dealer.
