Warranty on 30kWh replacement battery?

[GerryAZ]

It is highly unlikely that the replacement battery was 30 kWh. If the replacement was under warranty by Nissan, then it would be beyond the 5-year, 60,000-mile capacity warranty (that was retroactively provided by Nissan on 2011 and 2012 models) and nearing the end of the 8-year, 100,000-mile defect warranty (replacement is covered for remainder of original warranty). If the replacement was paid for by the former owner, then the 5/60 and 8/100 warranty started over on the installation date. Capacity warranty is 8 capacity bars to qualify for replacement.

I may be totally wrong about the 30kWh replacement in my 2012. I was assuming that was the case because the first few months of ownership had my GOM at 119 miles.

That's a 24 kWh battery. The 2011/2012 had a notoriously optimistic GOM when the battery was full, and would show over 100 miles when fully charged:

Either way, would the replacement battery still have a 30% over 5 years or 60,000 mile warranty on it? Can an older 2012 LEAF with a replacement battery go into a dealer and get another battery under warranty due to degradation?

Echoing what Gerry said, Yes, if it was a paid replacement and not a warranty replaced battery, it would have full coverage on the battery just like a new car. That's highly unlikely--most likely it was simply a warranty replaced battery. To know, you'd have to go ask your dealer for the service history.

That said, once the battery has been replaced--either by warranty replacement or purchase, it is the new chemistry just like a later model year car. That means it will degrade MUCH slower than the original 2011/2012 batteries.

Unless you need the range, I would start setting a charge timer now to 80% charge, as you live in a climate that is not good to Nissan Leaf batteries. Hawaii never gets cold, so the Leaf sees accelerated degradation there.

It would make no sense that a warranty replacement battery have another warranty. That would imply a LIFETIME replacement battery warranty.

It would be easy for people to abuse their batteries and then demand new one constantly.

I think that one replacement is very fair, especially for an old Leaf..

30 KWH batteries replaced under warranty carry the remainder of the original warranty. I.E. if you have the battery replaced at 45,000 mi after 2 1/2 years, the new battery is warranted for 55,000 mi or 5 1/2 years whichever comes first. If you purchase a battery outright then it comes with a new warranty of 100,000 miles or 8 years whichever comes first. I don't know of anyone who has purchased a 30 KWH battery outright.

24 kWh batteries work the same way. I think there's a minimum warranty duration of 6 or 12 months, however--to cover obvious defects in the new battery.
