The best battery for a Pajero Sport in Australia is one built to the D31L (N70ZZL) size class, since that is what Mitsubishi fits at the factory across QE and QF series diesels. Stock lead acid batteries in this size run about 700 to 830 CCA. A sodium ion replacement in the same footprint, such as the SC-NA1280, gives you more cranking amps, three times the cycle life, and no maintenance, for around the same price as a premium lead acid 4WD battery.
If you are chasing the best battery for Pajero Sport Australia conditions, the stock answer is not exciting. Mitsubishi ships every Pajero Sport sold here with a lead acid battery in the D31L size class, badged by suppliers as N70ZZL, and it behaves like every other lead acid battery once an Australian summer or a few years of short trips get hold of it. It loses cranking power in the heat, sulfates on the shelf if the vehicle sits, and needs replacing every three to four years even with careful use.
This guide covers what actually comes fitted to a Pajero Sport, why the standard lead acid unit is the weak link in an otherwise tough vehicle, and where a sodium ion battery fits as a drop in size class upgrade. We will also cover dual battery setups, since a lot of Pajero Sport owners run one for camping and touring.
What Battery Does a Pajero Sport Use in Australia?
Every Pajero Sport sold in Australia since the QE series launched in 2015 has been diesel only, using the 2.4 litre 4N15 engine (and later the updated MIVEC version in the QF facelift). Mitsubishi and the aftermarket both fit these vehicles with a 12V lead acid battery in the D31L group size, sold under part numbers like N70ZZL, N70ZZLX, or 105D31L depending on brand.
| Pajero Sport variant | Approximate case class | Typical CCA | Notes |
|---|---|---|---|
| QE series 2.4L diesel (2015 to 2019) | D31L class, N70ZZL | 700 to 830A depending on brand | Dimensions roughly 300mm long by 172mm wide by 220 to 225mm tall |
| QF series 2.4L MIVEC diesel (2020 onward) | D31L class, N70ZZL | 700 to 830A depending on brand | Same size class as QE, confirm tray and hold down clamp against your specific build |
| Dual battery setups (factory or aftermarket tray) | Varies by tray | N/A, deep cycle or dual purpose rating matters more than CCA | Second battery is chosen to suit the tray rather than to match the cranking battery exactly |
We are not yet able to confirm an exact tray and terminal fitment for every Pajero Sport model year, since Mitsubishi has made minor battery tray and hold down changes across the QE and QF run. Before you buy, check your current battery's dimensions and terminal layout against the SC-NA1280 datasheet, or get in touch with SaltyCells and we will confirm fitment for your specific build and year.
Why Lead Acid Is the Weak Point in an Otherwise Capable Vehicle
The Pajero Sport is built for touring, and a lot of owners take it well past the black top, onto corrugated tracks, through river crossings, and into 40 plus degree heat in the outback. None of that bothers the engine, the diff locks, or the suspension. It does bother a lead acid battery.
Heat is the biggest issue. Lead acid batteries lose life expectancy roughly twice as fast for every 8 to 10 degrees above 25°C that they sit at, and a Pajero Sport engine bay in central Queensland or the Pilbara in January runs a long way above that. Add in the classic Australian pattern of short suburban trips that never fully recharge the battery, then a long touring trip where the battery is asked for everything it has, and three to four years is a realistic ceiling, not a worst case.
If you are ever stuck with a flat battery a long way from town, NRMA and RACQ callout data consistently shows batteries as the single biggest reason for roadside assistance callouts in Australia. For a vehicle whose whole purpose is getting further from town, that is the wrong failure point to have.
Sodium Ion vs Lead Acid for a Pajero Sport
| Feature | Stock lead acid (D31L/N70ZZL class) | SC-NA1280 sodium ion ✓ |
|---|---|---|
| Capacity | ❌ Similar physical size, CCA 700 to 830 | ✅ 80Ah, approximately 1,500A CCA |
| Cycle life | ❌ 300 to 500 cycles typical | ✅ 3,000+ cycles at 60% depth of discharge |
| Weight | ⚠️ 18 to 22kg typical for this class | ✅ 11.0kg |
| Cold performance | ❌ Degrades noticeably below 0°C | ✅ Rated to minus 30°C discharge |
| Heat tolerance | ❌ Degrades fastest above 25°C | ✅ Rated to 70°C discharge |
| Warranty | Typically 12 to 24 months | 3 years |
| Typical price | $210 to $350 | $399 |
The weight difference alone is worth noting for anyone who has fitted a dual battery system, bull bar, and drawers to a Pajero Sport and is watching the GVM. Swapping to a sodium ion unit that weighs roughly half of a comparable lead acid battery gives some of that payload back.

Which SaltyCells Battery Suits the Pajero Sport
Because the Pajero Sport's factory battery sits in the D31L size class, the closest match in the SaltyCells range is the SC-NA1280. It sits in the same broad footprint as the N70ZZL class battery already in your engine bay and gives you a meaningful CCA increase over the stock unit.

View the Full Range →Dual Battery Setups and the Pajero Sport
A large share of Pajero Sport owners run a dual battery system for fridges, camp lighting, or winches, whether that is a factory option or an aftermarket tray under the bonnet or in the cargo area. If you are planning or rebuilding a dual battery setup, this is a good time to reconsider the whole system rather than just the starting battery.
A sodium ion starting battery paired with a sized correctly deep cycle or lithium auxiliary battery gives you a lighter, more heat tolerant system overall, which matters more the further you get from a powered site. If you are unsure how the two batteries in your system should be matched, our installation guide covers the basics of isolators, DC to DC chargers, and sizing an auxiliary battery correctly.
Installing a Sodium Ion Battery in Your Pajero Sport
Fitting a sodium ion battery in the correct size class is a straightforward swap, the same process as replacing any 12V lead acid battery: disconnect negative first, then positive, remove the hold down clamp, lift the old battery out, and reverse the process with the new one. No reprogramming or BMS setup is required for a straight starting battery replacement.
If your Pajero Sport has stop start technology or an aftermarket idle reduction system fitted, mention this when you order so we can confirm compatibility. Full step by step detail is in our installation guide.
Frequently Asked Questions
Australian delivered Pajero Sports (QE and QF series, 2015 onwards) use a 12V battery in the D31L size class, commonly sold as N70ZZL, with CCA typically between 700 and 830 depending on brand.
Yes. Every Pajero Sport sold new in Australia has used a diesel engine, either the original 2.4 litre 4N15 or the later MIVEC updated version, so there is no petrol variant to consider for battery sizing here.
Yes, the physical installation is the same as fitting any 12V lead acid replacement. The main thing to check first is that the physical dimensions and terminal layout match your current battery or tray.
Sodium ion cells are rated for discharge up to 70°C, well above what a lead acid battery is built to handle long term, and they do not suffer the same accelerated aging that heat causes in lead acid chemistry.
Your starting battery and auxiliary battery do not need to be the same chemistry or brand, but they should be sized and isolated correctly. Check our installation guide or contact SaltyCells if you are planning a new dual battery system.
The Bottom Line
The Pajero Sport is a genuinely capable tourer let down by the same lead acid battery every other vehicle in its class puts up with: heat sensitive, short lived, and the single most common reason for a roadside callout in Australia. A sodium ion replacement in the correct D31L size class gives you more cranking power, a third of the weight impact, and years longer between replacements, without changing anything else about how your vehicle runs.
