Hello all -

I have a 2018 Countryman SE All4 E (hybrid) and when I got it, I would see ~18 miles per charge.

6 years later I'm now seeing no more than ~12 miles/charge, so I've lost 33% of the value of the hybrid option.

Questions for the group:
1) has anyone had success reconditioning their MINI hybrid battery - I see that it's an easy option for Toyota Prius etc, but what about MINI/BMW design?
2) the warranty is 8 years/80000 miles and I'm below both. What constitutes a "failure" such that MINI would be required to replace the battery? Anyone have experience with MINI on this question?

Thanks

 

From the warranty I found online (this was the 2023 version but I imagine it's the same):

Due to its inherent technical design, the high-voltage lithium-ion battery’s capacity will decrease over time and with use. If an authorized MINI dealer’s capacity check concludes that the net battery capacity is less than 70 percent of its original nominal value when it was new, this level of capacity loss is considered excessive.

Do you have a copy of your warranty in your glove box?
