Volvo S60 Battery: The Part Everyone Blames First, Not Always Correctly
On the Volvo S60, the battery takes the blame for most no-start situations, and often rightly so — it's a sensible first check. But it isn't always the genuine cause, which is worth establishing before paying for a new one that turns out not to solve anything.
Volvo S60 Battery: What It Does
The Volvo S60's 12V battery handles engine starts and keeps electrical systems running whenever the engine isn't. On stop-start versions, that job gets much harder, since the engine switches off and restarts constantly — which is why it specifically needs an AGM or EFB battery, not a standard one.

A Genuinely Useful Piece of Context Worth Knowing About Volvo's Electrical Architecture — Volvo S60 Battery
If your main battery keeps draining despite everything appearing switched off, this is genuinely worth knowing: on related Volvo models with a shark fin roof antenna, this housing has its own small, separate internal battery, and documented cases have found a fault specifically with this small battery causing the main car battery to drain. It's worth asking a dealer specifically whether this antenna module has been checked if you're chasing an unexplained drain.
It's also genuinely worth knowing a useful diagnostic principle: if a replacement battery experiences the exact same drain pattern as the original, this points toward a genuine electrical system fault rather than the battery itself being faulty.
