Mitsubishi Outlander Battery Replacement Sydney — Petrol, Auto Stop-Start & PHEV 12V Auxiliary

Battery Brands Warehouse stocks the correct battery for every Outlander variant — including Q85 EFB for Stop-Start models and 12V AGM auxiliary batteries for PHEV hybrid systems. Warehouse-direct pricing, drive-in fitting.
Understanding Mitsubishi Outlander Battery Requirements
The Outlander spans several drivetrain technologies — getting the wrong battery type can cause rapid failure, disabled Stop-Start, or a PHEV that won't enter READY mode.
Standard Petrol Outlander — 2.0L, 2.4L & 2.5L
Uses standard Japanese JIS casing. Maintenance-free calcium batteries deliver reliable starting power for everyday family driving.
Recommended: 55D23L / 75D23L / 85D23L — 520–650 CCA depending on engine and year.
Auto Stop & Go (AS&G) Stop-Start Models
AS&G rapidly cycles the battery in city traffic. A standard calcium battery cannot handle this and will fail within months. Requires a high-cycling Q85 EFB with fast charge acceptance.
Recommended: Q85 / N55 EFB — 620–680 CCA. Do not substitute with a standard battery.
Outlander PHEV — 12V Auxiliary Battery
The PHEV relies on a separate 12V auxiliary AGM battery in the rear cargo area to power computer relays, displays, and high-voltage contactors. If this fails, the vehicle cannot enter READY mode regardless of main battery charge.
Recommended: S46B24L / LN1 AGM — 450–550 CCA. Must be AGM.
Next-Gen Outlander GM/GN (2021–Present)
Switched to a European DIN platform with updated battery specifications for both petrol and PHEV variants.
Recommended: LN2 / DIN55 / LN2 AGM — 600–700 CCA.

Frequently Asked Questions
Q: My Outlander PHEV won't start even though the hybrid battery is full. Is it a 12V battery issue?
A: Almost certainly yes. The 12V auxiliary battery powers the computer relays, displays, and high-voltage contactors. If it drops below operating voltage, the vehicle cannot enter READY mode regardless of main battery charge.
Q: Can I fit a standard battery to an Outlander with Auto Stop & Go?
A: No. AS&G models require a Q85 EFB. A standard lead-acid unit will fail within 6–12 months and may disable the engine shut-off feature.
Q: How long does a drive-in battery replacement take?
A: Testing, fitting, and memory preservation typically takes 10–15 minutes. Walk-ins welcome.
Q: Does the next-gen Outlander (2021+) use the same battery as older models?
A: No. The GM/GN generation switched to a European DIN platform. Drive in and we'll confirm the exact fitment for your build date and variant.
