Methodology · 14-day cycle
All measurements taken on a retail unit purchased through normal channels at MSRP. The unit was bench-cycled for 14 days in our Victoria BC lab. Display values calibrated against reference instruments. Battery values are the average of three fresh-cycle runs; the reported figure is the median. Pricing and availability figures accurate as of Apr 14 2026.
