Most Nissan Navaras sold in Australia, both the D40 and the NP300, run a standard four cylinder diesel and take a compact 70 to 77Ah battery around 276 to 278mm long. The SC-NA1270 (70Ah, 1,200A CCA, 279×175×189mm, $349) is the closest sodium ion match. Only the less common D40 3.0 litre V6 diesel needs the larger SC-NA1280.
If you have ever gone looking for the best battery for your Nissan Navara in Australia, you have probably noticed the advice online is a mess. Some sites point you to a D26 size battery, others quote a DIN75, and a few forum threads mention people forcing a bigger 105D31 or N70 battery into the tray and finding it a tight, awkward fit. That confusion is not your imagination. The Navara has been sold here across two generations, D40 and NP300, with two very different engine options, and the battery size genuinely changes depending on which one you have under the bonnet.
This guide sorts out exactly what size your Navara needs, why most owners are being sold an oversized battery without realising it, and where a sodium ion starter battery fits into the picture if you are sick of lead acid batteries dying on you every two to three years in the Australian heat.
What Size Battery Does the Nissan Navara Actually Take?
There is no single "Navara battery." The correct size depends on the engine, not just the model badge.
| Navara variant | Common battery size class | Typical CCA | Typical Ah |
|---|---|---|---|
| D40, 2.5 litre 4 cylinder diesel (2005 to 2014) | D26 class, ~276 to 278×175×190mm | 680 to 780 CCA | ~71Ah |
| D40, 3.0 litre V6 diesel | D31/N70 class | 720 to 830 CCA | ~95Ah |
| NP300/D23, 4 cylinder diesel (2015 to 2025) | D26 class, ~275 to 278×175×190mm | 580 to 760 CCA | 63 to 77Ah |
Despite Nissan's internal chassis code for the current generation being "D23," this is not the JIS D23 battery group size, a common point of confusion. The actual battery fitted to the standard NP300 is closer to D26 class, essentially the same footprint as the earlier D40 four cylinder. Always check your current battery's label for its exact size code and CCA rating before ordering a replacement.
In plain terms: if you drive the standard four cylinder diesel Navara, in either generation, and that is most Navaras on Australian roads, your battery bay is built for a compact 275 to 280mm long battery, not the bigger 300mm plus batteries commonly fitted to HiLux, LandCruiser or Patrol.
Why This Matters: The Oversized Battery Problem
Search enough Navara owner forums and you will find people describing a "tight fit" after installing a bigger, higher CCA lead acid battery, or physically modifying a tray to squeeze one in. That is not a coincidence. A battery built for a D31 or N70 size vehicle is roughly 300 to 306mm long. The standard Navara bay is closer to 276 to 278mm. That is a real world gap of 25 to 30mm, enough that the battery clamp will not sit properly, or the case will not clear surrounding brackets and hoses.
This is worth knowing before you buy, because plenty of battery fitment tools and generic retailer charts default Navara owners to a bigger, higher spec battery on the assumption that bigger is always safer. For most Navaras, it is not a safety margin, it is a battery that does not actually fit the tray it needs to sit in.
The Sodium Ion Alternative for Navara Owners
| Spec | Navara D40/NP300 factory (4cyl diesel) | Salty Cells SC-NA1270 ✓ |
|---|---|---|
| Capacity | ~71 to 77Ah | 70Ah |
| Cold cranking amps | 580 to 780A | ~1,200A peak |
| Dimensions (L×W×H) | ~276 to 278×175×190mm | 279×175×189mm |
| Weight | ❌ ~18 to 20kg | ✅ 11.2kg |
| Cycle life | ❌ 300 to 500 cycles, 2 to 3 years in Australian heat | ✅ 3,000+ cycles, 3 year warranty |
| Price | Varies by brand | $349 |
The SC-NA1270 lines up with the standard four cylinder Navara almost to the millimetre: 3mm longer, identical width, and 1mm taller than the factory footprint. It also comfortably exceeds the factory CCA rating while weighing roughly half what the lead acid equivalent does, a genuine benefit if you are also carrying a canopy, dual battery setup or touring gear.
Lead acid and AGM starter batteries in Australia routinely fail within two to three years, faster again if the vehicle sits in direct sun, does short trips around town, or runs accessories like a dashcam or fridge that draw power while parked. See why sodium ion beats lead acid for the full technical case. Sodium ion cells are discharge rated from minus 30°C to 70°C, well beyond what a lead acid battery sitting in an engine bay through an Australian summer can handle without accelerated degradation, and a quality sodium ion starter battery is rated for 3,000 or more charge cycles, which is why NRMA and RACQ callout data consistently shows flat batteries as one of the most common roadside assist jobs in the country.
Which Salty Cells Battery Suits Your Navara?
For the standard four cylinder diesel Navara, D40 or NP300, which covers the majority of Navaras on Australian roads, the SC-NA1270 at $349 is closely matched to your factory battery bay. For the D40 3.0 litre V6 diesel variant only, the SC-NA1280 at $399 is sized for the larger V6 battery bay.

One honest caveat: we are still building our verified fitment database for the new range, and exact case dimensions have not yet been confirmed against every Navara variant and year by our supplier. Send us your build year, engine and current battery part number via the FAQ page and we will confirm size, terminal orientation and fit before you order.
View the Full Range →How to Install Your New Battery
Swapping to a sodium ion starter battery is a straightforward drop-in job for most DIY capable Navara owners, the same process as any lead acid replacement: disconnect negative first, then positive, remove the hold down clamp, swap the battery, and reconnect positive first, then negative. Full step by step details are in our installation guide. If your Navara has any aftermarket alarm, dual battery system or dashcam wired directly to the battery, note down the wiring before you disconnect anything.
Frequently Asked Questions
Most Navaras, D40 and NP300, with the standard four cylinder diesel engine, need a compact 70 to 77Ah battery around 276 to 278mm long. Only the D40 3.0 litre V6 diesel needs a larger 95Ah class battery.
Not easily. A battery built for a HiLux, LandCruiser or Patrol is typically 300mm or longer, which will not comfortably fit the standard Navara's 276 to 278mm bay. Several Navara owners online report a tight or forced fit after trying this. Stick to the correct size for your variant.
The SC-NA1270 is dimensionally very close to the standard four cylinder Navara's factory battery, and installs the same way as a lead acid replacement. As with any battery swap, confirm terminal position and bay dimensions against your specific vehicle before ordering, particularly on older or unusual variants.
Sodium ion cells are rated for 3,000 or more charge cycles against a 3 year warranty, well beyond the typical 2 to 3 year lifespan of a lead acid battery in Australian conditions, particularly in hot climates or with short daily trips.
Yes. Terminal polarity and bay dimensions both matter. Confirm both against your existing battery before ordering, especially if your Navara has been modified with an aftermarket dual battery system.
The Bottom Line
Most Nissan Navara owners in Australia are driving the standard four cylinder diesel, D40 or NP300, and need a compact 70 to 77Ah battery, not the bigger, higher CCA battery that generic fitment charts often default to. The SC-NA1270 is a close physical and electrical match for that majority, with the SC-NA1280 reserved for the less common V6 diesel D40. Either way, a sodium ion starter battery gives you 3,000 plus cycles, better heat tolerance and roughly half the weight of the lead acid battery it replaces. Confirm your fitment via the FAQ page, then shop the range.
