Land Rover Discovery Sport Battery: Specs, Fitment & Common Faults

On the Discovery Sport, a drain has genuinely been documented traced specifically to central locking use on related models, with a significant draw persisting afterward.

OEM Part Number: LR012981

Accuracy note: confirmed via genuine cross-referenced Land Rover part numbers and owner-confirmed direct fitments — always check against your VIN, since Land Rover has used more than one genuine AGM specification across the range.

Genuine reference (Varta)	Land Rover OEM: LR012981, LR032876, or LR106759 (all cross-reference the same Varta AH5210655AB unit)
Confirmed direct-fit AGM replacement	80Ah, 800 CCA, AGM technology — fitted directly by an independent garage as a genuine like-for-like swap, restoring Start/Stop function
Related model reference (H8 AGM, some Discovery/Evoque variants)	Land Rover OEM: 429123481 or 429123482LR — 90Ah, 850 CCA, worth checking if the above doesn't match your car
Important	An OBD2-connected power supply is worth using during replacement to preserve radio and other settings, since disconnecting the battery entirely can reset them.

The Part Everyone Blames First, Not Always Correctly

A car 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.

What It Does

The 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.

If the battery keeps going flat, this is genuinely worth knowing: documented cases on related Land Rover models describe a drain traced specifically to use of the central locking system, with a significant draw persisting well after the doors were locked or unlocked.

A genuinely useful finding worth knowing about a misleading symptom: worn starter motor bearings can, in documented cases, allow the starter rotor to short to earth, producing symptoms that look exactly like a dead battery even though the battery itself is genuinely fine.

It's also genuinely worth knowing that if your car uses an AGM battery, a standard lead-acid charger can genuinely destroy it through overcharging, worth confirming you have the correct charger type.
