OEM Part Number: Type 096

Accuracy note: The V40 (2012–2019) takes a 278 mm type 096 EFB or AGM (70–75Ah / 700–760A) on every stop-start engine, with a 315 mm type 100 AGM (80Ah / 800A) listed for the D4 and T5; non-stop-start cars use a standard 096 (77Ah / 780A, Varta E44). Stop-start V40s also carry a small 9–13Ah AGM support battery (Varta AUX9 / AUX14 class) that keeps the electronics alive during restarts and causes a "start-stop unavailable" message when it fails. After a main battery change the car needs a battery data reset. Check the three-digit type code, Ah and CCA printed on the battery you are removing before ordering — this model was built in more than one size. Stop-start cars must have an EFB or AGM battery, never a standard one.

D2 1.6 / 2.0, D3, T2 / T3 / T4 stop-start	Type 096 EFB (75Ah / 700A) or AGM (70Ah / 760A). Aftermarket: Yuasa YBX7096 EFB (75Ah / 700A) or YBX9096 AGM (70Ah / 760A); Varta N70 EFB / A7 AGM; Bosch S4E 081 / S5A 080
D4 2.0 190 / T5 stop-start	Type 096 AGM (70Ah / 760A) or 100 AGM (80Ah / 800A, Varta A6 / Bosch S5A 110). Aftermarket: Yuasa YBX9115 AGM (80Ah / 800A); Varta A6 / F21; Bosch S5A 110
Without stop-start	Type 096 standard (77Ah / 780A, Varta E44). Aftermarket: Yuasa YBX3096 (76Ah / 680A); Varta E11 / E39; Bosch S4 008
Support battery (stop-start cars)	Small AGM, 9–13Ah / 120–200A (Varta AUX9 / AUX14 class) — confirm via VIN

Genuinely worth knowing: a Volvo V40 Forums member directly found registration-based lookup tools recommending a smaller 760A battery, when their own car's user guide specified 800A — worth checking your owner's handbook rather than trusting a registration lookup alone, particularly on D2/diesel automatic variants.

Volvo V40 Battery: The Part Everyone Blames First, Not Always Correctly

On the Volvo V40, more non-starts get pinned on the battery than on any other single component, and that assumption is correct often enough to justify checking it first. It's not always the real cause, though, so it's worth confirming before spending money on a replacement that doesn't fix the problem.

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.

Volvo V40 Battery: What It Does

On the Volvo V40, every engine start and every moment the electrical systems run without the engine turning draws on the 12V battery. Stop-start puts far more demand on that battery than older designs, given how often the engine cycles off and on — hence the need for an AGM or EFB battery instead of a standard type.

A Genuinely Useful Piece of Context Worth Knowing About Volvo's Electrical Architecture — Volvo V40 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.

Worth knowing about a genuinely alarming, real account on related models: a complete, total drain traced to the vehicle's telematics control module has been resolved in documented cases by the manufacturer's own engineers remotely applying a software patch — worth knowing the fix for a severe drain isn't always a physical part.

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.
