Choosing the right battery for the Mitsubishi Pajero IV, produced from 2006 onwards, is essential for ensuring reliable starts and the proper operation of all onboard electrical systems. This SUV, known for its durability and off-road capabilities, has several engine variants, and each requires a battery tailored to its power demands. Since the Pajero IV does not use a Start-Stop system in these configurations, the focus is on robust, conventional lead-acid batteries capable of handling high starting currents.
For the 3.0 4WD petrol engine, the recommended battery capacity ranges from 70 to 75 Ah, with a cold cranking amperage between 540 and 630 A. These specifications ensure the vehicle can start reliably, even in colder climates, without straining the battery. Example of suitable models include Bosch S40 27, Exide EA755, Exide EB705, and Varta E24. An important consideration is the terminal layout, as this version of the Pajero may require a battery with the positive terminal on the left side. Additionally, while many cars use the common B13 battery mounting system, this vehicle needs a less typical type such as B01 or B9, which is worth checking before making a purchase.
The 3.8 V6 petrol engine and the 3.2 DI-D diesel engines, including the 4WD and TD 4WD variants, demand larger and more powerful batteries. These engines require batteries with a capacity between 95 and 100 Ah and a cold cranking amperage from 720 to 830 A. This higher capacity is necessary to cope with the strong starter motor requirements of both the V6 petrol and diesel engines, which have higher compression ratios. Examples of compatible batteries are Bosch S40 29, Exide EA955, Exide EB955, Lucas LS250, and Varta G8. As with the smaller engine, these variants also feature an unusual battery terminal layout, often with the positive pole on the left, and use special mounting types like B01, B1, or the Korean B1 standard instead of the more widespread B13.
When selecting a battery for the Pajero IV, it is wise to consider the driving conditions. Off-road enthusiasts or drivers in cold regions may benefit from choosing a battery closer to the maximum amperage range, as frequent cold starts or short trips can be demanding. Another interesting detail is that Japanese SUVs like the Pajero often have battery trays designed for specific regional markets, which explains the non-standard mounting systems and terminal layouts. This means that European or American replacement batteries sometimes require adapters or careful attention to dimensions before installation.
In conclusion, the Mitsubishi Pajero IV requires robust lead-acid batteries, with specifications varying by engine size. The 3.0 petrol engine works well with 70–75 Ah units, while the larger petrol and diesel engines need 95–100 Ah batteries with high cold cranking power. Paying attention to the terminal orientation and the less common mounting systems is crucial to ensure a proper fit. Using high-quality examples such as Bosch S40 27 or 29, Exide EA755 or EA955, and Varta E24 or G8 will provide the reliability needed for both everyday driving and adventurous off-road journeys. A well-chosen battery not only supports starting performance but also ensures that all electrical systems—from headlights to navigation—function flawlessly, keeping the Pajero ready for any challenge.

I would like to ask , why the Mitsubishi Pajero IV 3.2 Di-DC mod 2008 is using 2 batterries and if it is nessesary if you dont use for example car burner
In the Mitsubishi Pajero IV 3.2 Di-DC from 2008, two batteries are used mainly because of the vehicle’s design and purpose. This model is built for off-road conditions, often equipped with many electrical consumers such as winches, additional lights, heaters, or a car burner (auxiliary heater). The dual-battery setup ensures stable power supply under heavy load and provides higher reliability when starting the diesel engine, which requires a strong cranking current, especially in cold weather.
Is it absolutely necessary if you don’t use a car burner or other power-hungry accessories? In theory, not always. A single battery with the right capacity and high enough starting current could be sufficient for daily driving. However, Mitsubishi designed the system with two batteries to maximize reliability in all conditions. Removing one battery may lead to weaker cold starts or voltage drops when several electrical systems are in use at the same time.
In short, the second battery in the Pajero IV is not only for the car burner but part of the overall concept of a heavy-duty off-road vehicle. It is possible to run it with one battery, but this comes with some risk of reduced durability of the electrical system and more difficult starts in harsh conditions.
