OEM Part Number: Type 096

Accuracy note: The Octavia Mk3 (2013–2020) takes a 242 mm type 027 (60–63Ah) on the smaller 1.0 / 1.2 / 1.4 petrols and a 278 mm type 096 (70Ah / 760A) on the 1.6 and 2.0 TDI and the vRS — standard where there is no stop-start, EFB or AGM where there is. The Mk4 (2020 on) is 096 EFB throughout, with a 12V auxiliary on the iV plug-in. Code the new battery after fitting. 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.

A Genuine, Vivid Example of What Goes Wrong Without Proper Coding — Skoda Octavia Battery

Worth understanding just how badly things can go if a battery replacement isn't coded correctly: one documented Octavia owner's car was "like a completely different car" after a battery swap without the correct Skoda-specific coding — digital oil temperature climbing to 107°C, fuel economy collapsing, coolant reaching temperature unusually quickly, stop-start no longer functioning, and cruise control working only intermittently. This wasn't a coincidence or an unrelated fault appearing at the same time; it was the direct, documented consequence of the car's systems not knowing a new battery had been fitted, and it's worth taking as a genuine warning against skipping this step to save money.

Real UK cost figures worth knowing: one Skoda dealer quoted just over £293 to replace the battery in a Mk3 Octavia VRS, with coding alone (if you supply your own battery) quoted separately at £52.50. Once you have the specific battery code for your car, you're free to source the physical battery from any reputable supplier — the code itself is what a specialist needs to complete the coding step, not a battery that has to come from Skoda specifically. Independent VAG specialists and some tyre/exhaust centres with the right diagnostic tools can complete this coding for meaningfully less than a dealer's own labour rate.

Skoda Octavia Battery: The Part Everyone Blames First, Not Always Correctly

A Skoda Octavia 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.

Skoda Octavia Battery: What It Does

The Skoda Octavia's 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.
