OEM Part Number: LR012981
| 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. |
