Warranty is not being honored
Size: Group 94
If you plan to purchase a product from Parts Synergy just know they will make it a headache to honor the product’s warranty. I reached out to them first and they kept ignoring my request by stating “Amazon order details are gone nothing we can do” yet I was able to pull up the order details. Amazon support stated to reach out to Bosch (battery’s manufacturer) and Bosch told me the seller is responsible to honor the warranty. I noticed Parts Synergy and they still are choosing not to honor the warranty. Amazon support sent them a message and Parts Synergy responded “contact Amazon” which just highlights the lack of customer service because the seller didn’t even realize it was an Amazon support agent. ... show more

Size: Group 94
The battery worked perfectly with my 2023 Mini Countryman S All4 model. I used the Veepeak Bluetooth OBD2 adapter along with the BimmerLink app to register the battery successfully. Installation was easy, and the battery registered without any errors. Highly recommend this combination for anyone needing to replace and register their Mini's battery. ... show more
