OEM Part Number: 560-600A

Accuracy note: confirmed for Corsa E (2014-2019) — owner reports and UK battery retailers consistently reference Type 027 as the standard factory fitment, with retailers advising against fitting a different size code (such as 096) without confirming compatibility first. Earlier and later generations may differ — always check the size and technology printed on your existing battery, or your reg, before ordering.

Corsa E, standard fitment	Type 027, typically 55-61Ah depending on trim, lead-acid or EFB
Corsa E, Start/Stop equipped	Type 027 EFB, around 60Ah, 560-600A (EN)
Case dimensions (027)	242mm long x 175mm wide x 175-190mm high, depending on technology

A Genuine, Documented Cause on Older Corsas: The CD30 Radio — Vauxhall Corsa Battery

If your Corsa C is an older model and the battery keeps going flat despite testing healthy, it's genuinely worth checking the factory-fit CD30 radio (made by Blaupunkt) before assuming a battery or alternator fault. Vauxhall issued a specific Technical Service Bulletin (reference 1973) covering a documented fault where a malfunctioning "CD-in-recognition" switch inside the radio causes it to self-activate, draining the battery overnight even with the car locked and the ignition off. Vauxhall's official remedy for cars within the affected production window was a modified replacement unit — but several owners with cars outside that specific window have reported the same fault still occurring, with Vauxhall declining to act since the cars technically fall outside the documented TSB range.

A genuinely useful, simple test: before spending money on a new battery, pull the radio fuse and see if the drain stops — a battery that holds charge fine with the radio fuse removed strongly points to the CD30 unit as the actual cause, regardless of whether your specific car technically falls within Vauxhall's stated TSB window.

Vauxhall Corsa Battery: The Part Everyone Blames First, Not Always Correctly

Ask anyone why their Vauxhall Corsa won't start and "the battery" is usually the first guess, and it's frequently correct, which makes it a reasonable starting point. It's not always right, though, so it's worth ruling out other causes before spending on a replacement that changes 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.

Vauxhall Corsa Battery: What It Does

On the Vauxhall Corsa, powering the engine start and running electrics while the engine's stopped both fall to the 12V battery. Stop-start technology puts significantly more strain on it than older designs, thanks to how frequently the engine cycles — explaining why a specific AGM or EFB battery is needed rather than a standard unit.
