I am starting this thread with the purpose to talk about the Shimano warranty for batteries and share the experiences to get our battery warrantied before it arrives to the 60% degradation.
Some bike suppliers like E-Thirteen, Spesh and others, when they see in this forum a customer with a problem, they quickly jump in the thread and provide a solution and normally covered by warranty. But as for Shimano, they do not even provide any help but tell their lawyers to remove any specification in the documentation, his programmers to remove any BATTERY LIFE number in e-TUBE app, so we do not have any documentation to backup a claim.
But luckily, documents are not erased in Internet and old documents can still be found. I am attaching one of the pages of a 2019 Shimano Steps Service Manual, where it specifies that the battery should have 80% of the charge at 500 cycles or 60% at 1000 cycles. But since then the number of 80% charge at 500cycles has disappeared from shimano documentation. But I suppose that the figure 80% charge at 500cycles as showed in this document is still legally binding.
Has anybody successfully used this specification to get Shimano warranty the battery at 80% charge?
