Volvo XC60 Battery: Specs, Fitment & Common Faults

A genuinely distinctive finding: the shark fin roof antenna has its own small internal battery, and a fault with it has been documented draining the main battery — plus a case resolved by a remote software patch from Volvo's own engineers.

OEM Part Number: 31255132

Accuracy note: Volvo has used several genuine part numbers across XC60 generations as the battery specification evolved — always confirm against your VIN, since some references require an additional foam surround to be ordered alongside the battery itself.

First-generation XC60 (2009-2017), AGM	Volvo OEM: 31255132 — 760 CCA
First-generation XC60, alternative reference	Volvo OEM: 30772236 or 30772216 (also referenced as 9139727) — note 30772236 requires foam surround 30757617 to be ordered separately
Current generation	Volvo OEM: 32344518
General guidance	Standard starter battery needs 800-850A cold-crank capacity with 80-95Ah, typically H7 or H8 AGM — always match the size to your specific model rather than assuming across generations.

The Part Everyone Blames First, Not Always Correctly

A car that won't start gets blamed on the battery more often than any other component, and it's right often enough to make that assumption a reasonable first check. But it's not always the actual cause, which is worth knowing before spending money on a replacement that doesn't fix anything.

Before you buy: battery size, capacity and type (standard vs AGM/EFB for stop-start systems) vary by trim and engine. Always confirm against your VIN before ordering.

What It Does

The 12V battery provides the power needed to start the engine and runs electrical systems when the engine isn't turning. On cars with stop-start technology, the battery works much harder than on older designs, since the engine switches off and restarts far more frequently — which is exactly why these cars need a specific AGM or EFB battery type rather than a standard unit.

A Genuinely Distinctive, Real Finding Worth Knowing About

If your main battery keeps draining despite everything appearing switched off, this is genuinely worth knowing: the shark fin antenna housing on the roof has its own small, separate internal battery, and one documented case found a fault specifically with this small battery was causing the main car battery to drain — a genuinely distinctive component many owners wouldn't think to check. If you're chasing an unexplained drain, it's worth asking a dealer specifically whether this antenna module has been checked, rather than assuming the fault must lie with the main battery or a more commonly suspected component.

A genuinely alarming, real account worth knowing about a different possible cause: one documented case on a car just two months old and with only 7,000 miles saw a complete, total drain — the remote key wouldn't work at all, and even a fully charged portable jump starter couldn't get the car going. This was eventually traced to the vehicle's telematics control module, and resolved by Volvo's own engineers remotely accessing the car and applying a software patch — worth knowing that sometimes the actual fix for a severe, total drain is a software update to this specific module rather than any physical part needing replacement.

It's also genuinely worth knowing a useful diagnostic principle: if a replacement battery experiences the exact same drain pattern as the original, this is a strong, real indicator that the underlying cause is a genuine electrical system fault rather than the battery itself simply being faulty — worth ruling this in clearly before buying yet another replacement battery on the assumption each one was just unlucky.
