2012 Nissan LEAF battery — common questions
- What battery group size fits the 2012 Nissan LEAF?
- Checked source records list Group 51R for the 2012 Nissan LEAF. BCI group sizes define the battery's physical dimensions and terminal positions. Do not infer terminal layout from the group number alone; match the current battery label or terminal layout before checkout.
- Why does this page list AGM for the 2012 Nissan LEAF?
- Current checked source records list AGM listed by sources for the 2012 Nissan LEAF. Because the source table on this page does not show an OEM battery-type source, treat this as a source-listed catalog requirement, not an owner-manual claim. Do not substitute a different battery type unless your owner's manual, current battery label, or a service source supports it.
- What CCA rating should I look for?
- Cold Cranking Amps (CCA) measures the battery's ability to start the engine at 0 °F. The CCA rating for this vehicle is not yet in the checked source records. Check the sticker on the current battery or your owner's manual for the baseline rating, then meet or exceed that number — especially in cold climates.
- Why does terminal position matter for battery replacement?
- Terminal position (positive on the left or right when facing the battery) determines whether the factory cable length reaches the correct post and whether the hold-down bracket fits. Confirmed terminal data is not yet in checked records for this vehicle. Verify the layout in the retailer's vehicle selector or check your current battery label before ordering.
