Choosing the right car battery size in New Zealand can be confusing. Japanese and European vehicles use completely different sizing systems, and picking the wrong size means it simply won't fit your car. This guide covers every battery size you'll encounter on NZ roads.
Understanding Battery Size Codes in NZ
New Zealand's vehicle fleet is dominated by Japanese imports (Toyota, Nissan, Mazda, Honda, Subaru) and a growing number of European vehicles (BMW, VW, Mercedes, Audi). Each uses a different battery sizing standard:
- JIS (Japanese Industrial Standard) — used by Toyota, Nissan, Honda, Mazda, Subaru, Mitsubishi
- DIN (European Standard) — used by BMW, VW, Mercedes, Audi, Skoda, Volvo
Japanese Battery Sizes (JIS)
NS40 (40B19L / 40B19R)
The smallest standard car battery. Fits compact cars like the Toyota Vitz, Suzuki Swift, Honda Fit/Jazz, Nissan March and many small hatchbacks. CCA ratings typically range from 300-340CCA. The "L" or "R" suffix indicates terminal position — check which side your positive terminal sits on before ordering.

- Check the owner's manual — the recommended battery size is listed in the specifications section
- Use our vehicle finder — search by make and model at bestbatteries.co.nz
- Call us — phone Contact us with your registration plate and we'll look it up
What Does CCA Mean?
CCA (Cold Cranking Amps) measures how much power a battery delivers in cold conditions. Higher CCA = easier cold starts. In Auckland's mild climate, CCA matters less than in colder regions, but always match or exceed your vehicle's minimum CCA requirement. A higher CCA battery is fine — a lower one could leave you stranded on a cold morning.
Standard MF vs EFB vs AGM — Which Do You Need?
- Standard MF (Maintenance Free) — suits most conventional petrol and diesel vehicles. The most affordable option.
- EFB (Enhanced Flooded Battery) — required for vehicles with start-stop technology (i-Stop, ISG). Better cycling performance than standard MF.
- AGM (Absorbed Glass Mat) — required for European start-stop vehicles and hybrid cars. Premium performance and longer lifespan.
Important: If your vehicle came with an EFB or AGM battery, you must replace it with the same type or higher. Downgrading to standard MF will cause premature failure.
