Notes on these figures

Storage charge · Shimano
Charge every 6 months in storage, store at 50% or above. No cycle-count spec is published.
Expected capacity · Bosch
80% capacity remaining after 1,000 cycles at 80% depth of discharge, 25 C.
Expected capacity · Shimano
SIXTY percent after 1,000 cycles, against Bosch's eighty. Twenty percentage points apart at the same cycle count -- battery health must be a per-brand curve, never an industry constant.
