OEM Part Number: 640-760A

Accuracy note: confirmed for F15-generation Juke (2010-2019) with Start/Stop — capacity and technology vary between petrol variants, so always check your existing battery's label or VIN before ordering.

Standard Start/Stop fitment	Type 027, EFB, 60-70Ah, 640-760A (EN) depending on variant
AGM alternative	Type 096, AGM, 60Ah, 680A (EN) — a valid factory-aligned upgrade path
Important	Never fit a standard lead-acid battery in place of EFB or AGM on a Start/Stop car — this will disable Start/Stop and isn't designed for the frequent cycling involved.

A Genuinely Useful, Real Diagnostic Technique Worth Knowing — Nissan Juke Battery

If you're chasing a parasitic drain, this is genuinely worth knowing: an amp meter with a clamp attachment fitted over the positive battery cable allows you to monitor current draw while systematically pulling fuses one at a time — watching for the reading to drop identifies which specific circuit is causing the drain. It's worth prioritising checking permanently-live circuits first, since these are the most likely culprits, rather than working through the fuse box in no particular order.

A genuinely real habit worth being mindful of: leaving the ignition key in the "accessory" position without the engine running, rather than fully off, for even a relatively short period, has been documented as capable of draining a battery within around 20 minutes on some examples — worth being mindful of this if you're prone to leaving the key part-way turned while waiting with the radio or other accessories on.

It's also worth knowing that on some models, battery problems have been widely enough documented on Nissan's forums that a premature failure on a relatively new car is genuinely worth raising directly with a dealer as a known pattern, rather than assuming you've simply had bad luck — it's worth asking specifically whether your car's battery batch has been associated with any documented issues before paying for a replacement out of pocket.

Nissan Juke Battery: The Part Everyone Blames First, Not Always Correctly

When a Nissan Juke won't start, the battery is the first suspect more often than anything else, and it's right often enough that checking it first is a reasonable move. It isn't always the actual cause though, which is worth knowing before paying for a replacement that solves nothing.

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.

Nissan Juke Battery: What It Does

Starting the engine and running electrical systems whenever the engine isn't turning — that's the Nissan Juke's 12V battery job. If it has stop-start, it works much harder than older designs, since the engine cuts out and restarts constantly, which is exactly why it needs a specific AGM or EFB battery rather than a standard one.
